Electrical System Design

Most RV’s and camper trailers utilize the same types of electrical systems as those used for an average small home. But in addition to the 110 volt electrical supply, there may also be lights, fans, a refrigerator, or other electrical devices which use a 12 volt supply, like that of a car or truck.

A 12-volt DC system powers the RV refrigerator to keep food cold while the RV or camper trailer is moving from place to place. The same goes for the lights and fans. It also keeps the on-board batteries fully charged. This system relies on the 110-volt AC electrical power supply for amperage.

It is possible to pull a 12-volt power supply from the RV or camper trailer's electrical system or 110-volt campsite power supply. Then the 110-volt supply can be stepped down to 12 volts after it is run through a power converter and to a particular appliance.

Rewiring a Classic RV

Most of RV systems will switch from the 110-volt AC to the 12 volt DC supply automatically when there is a power interruption. These two electrical systems are treated independently from each other when diagnosing electrical problems, except for determining power to the converter. This translates to:

  • 110 volt power-- > converter-- > 12 volt power-- > 12 volt breaker box -- > refrigerator or lights

As in a home, the 12-volt system has its own set of breakers to control each circuit. The lights, fans, or refrigerator may each be on their own circuits, depending on the amperage required. If the converter is supplying 12 volts to the breaker panel and the breakers test positive for voltage, this leaves the wiring or the particular appliance at fault.

Essential Tools and Resources

  • If you are not familiar with electrical wiring or troubleshooting electrical systems there are some very good books available to help you understand and repair common RV electrical problems. I would recommend RV Electrical Systems: A Basic Guide to Troubleshooting, Repairing and Improvement to any novice and experienced electrician alike. It will be an enormous aid to understanding RV electrical systems.
  • Another must for tracing down electrical problems is a voltage meter. This handy tool will allow you to check the circuits for continuity and for the correct voltage required for each breaker. A simple test light can be used but will not test for broken circuits caused by bad wiring or other electrical problems. Both of these tools are inexpensive to own and will more than pay for themselves over time. The voltage meter can be used for home electrical problems as well as any other electrical related problem. Both are offered on this page for a reasonable price.

Troubleshooting Common 110-Volt Problems

  • The 110 volt outlets used in some RVs and camper trailers are prone to shorts because of the way they are installed. Some are merely clipped onto the wiring by cutting into the wires. These types are notorious for not working correctly. Replace these types of outlets with standard house types to put and end to loose connections. Since some of the walls are so thin, a smaller receptacle box may be required for the outlet to fit flush in the walls.
  • Ground fault interrupter outlets are another common cause of electrical problems. These are located in places where a possibility exists of someone touching them with wet hands. They automatically break the circuit when moisture comes in contact with the outlet to prevent shock to the person touching them. A simple reset button must be pressed for the circuit to once again be completed. On occasion they will need to be replaced or the other outlets on the line will not work either. Pay close attention to the instructions when replacing these GFIs.
  • In older RVs and camper trailers you may still find fuses instead of circuit breakers. Since the advent of many new electrical devices, these older fuse systems may not provide enough amperage to handle a microwave or other high amp appliance without blowing a fuse or kicking a breaker. Simply replacing the fuse or breaker with a higher amp substitute may be all that’s required. Replacement of the entire breaker box may be the only option remaining if this doesn’t solve the problem.
  • The newer RVs and camper trailers may have two RV A/C rooftop units which require more amperage than the older models to operate without kicking the standard 30-amp power supply used by many campgrounds. Fortunately, many campgrounds and RV parks now provide 50-amp service for these types of units. When making reservations or checking in, be sure to ask about the availability of a 50-amp hook-up if you own a unit with multiple A/C units.

Keeping your electrical systems in good and safe working order insures a trouble free camping trip with no sudden power outages to ruin the trip. Most problems can be repaired easily if you understand how the system works. RV electrical manuals along with a few inexpensive tools are well worth the cost of their purchase.

If you are completely confused by electrical wiring there are also some very good basic books to start you off. It isn’t very hard at all to check electrical circuits, switches or outlets with an inexpensive voltmeter. Just remember, when touching any wires be sure the power to that particular circuit is off. If in doubt, turn off the main breaker or unplug the RV or camper trailer from the power supply. Happy camping!

      Hi Eric, a bit more info may help me solve the problem. What exactly does the Digital Control Panel control? I'm not familiar with all makes of campers and motorhomes so perhaps you can enlighten me on your particular model. I need info such as what electric system does the panel operate on, 110volt AC or 12 volt DC?

      Hey Danny, have you checked the negative battery cable where it attaches to the steel frame? A bad ground will cause all sorts of strange problems. Also, there may be a relay/breaker in-line on the positive battery cable leading to the converter. Not all campers have this but it's possible yours does.

      Hi Randy, great post!

      Just this weekend while we were retracting the slide, the whole power system went dead mid way. No clock radio, no lights, no gas monitor, no jack, nothing. I plugged into my truck, and everything came on, and i was able to finish the slideout and get connected to the truck.

      Brand new batteries (4 x 6V in parallel/series). I just finished testing all the 12V fuses (all passed) and for no reason also replaced them all. No change.

      Plug into shore power, and everything comes back on.

      So Batteries = nothing

      7 pin connector = power

      shore = power

      Any suggestions?

      Matthew, there should be a fuse or breaker in the 12 volt DC power panel, but this sounds more like a switch or relay problem. Check the wiring harness going to the towing vehicle as there may be a short causing the problem. Let me know if this helps you find the problem.

      Bubba, sorry but your comment went into my spam filter for some reason and I just found it. Sorry for the delay in responding. This either a power converter problem or a bad battery ground. Try connecting a good battery charger up and if everything works correctly the converter is probably at fault.

      JD, I'm only suggesting it's the compressor but mot for sure. You can have capacitors tested or you can do this yourself with a multimeter set on OHMS.

      When you place the probes of the meter on the terminals you should get a random number which decreases in value the longer the probes are in contact. A steady number--or none at all--means the capacitor is bad. Hope this helps solve the problem. Feel free to ask for more info if needed.

      JD, this sounds like a compressor problem. Is the compressor very hot to the touch after it shuts down? It seems it's overloading--thus the flickering lights--for some reason and drawing too many amps.

      You can borrow/rent an amp meter and compare the reading to the normally required amperage, usually located on or near the compressor. Good Luck!

      Randy evertime time that you turn on the a/c it will run for a few minutes then every light will start flickering and the unit shuts down and try to start back. Have already replaced a/c up top furnace and converter and thermostat on wall.

      Hey Sean, apparently the outdoor outlets and light are on a circuit with a loose connection at one of the outlets. As the out door outlets and light will be on a GFI circuit you'll need to check the connections to both GFI circuits. Let me know what you find out if you can.

      I have a 2012 KZ Sportsmen in which the outdoor outlets (110V) and light aren't working. All interior equipment/outlets are working, no breakers are tripped or fuses popped. Neither outdoor outlet is a GFCI (one by the main door, one in the outdoor kitchen slide out) Wondering what could cause outdoor electric to fail, but inside electric works and no breakers or fuses appear to be the problem? Any ideas? TIA.

      Orlando, check the 12 volt power panel for a tripped breaker or blown fuse. If everything seems okay there then check the 110 volt power panel for a tripped power converter breaker. If the breaker isn't tripped, check the negative battery cable where it attaches to the steel frame of the camper. A bad connection here will cause all sorts of problems. Check the voltage at the battery. If the power converter is working properly you should get a reading of at least 13+ volts.

      You can also connect a good battery charger to the battery--not a trickle type--and if the lights work then more than likely the power converter is bad.

      Regarding the piercing noise encountered and as an "FYI" and additional info, there was a bad batch of Elexir electric converters produced back 3-4 years ago and it could be that the converter is failing. It is my understanding too that some of these converters DO have an audible "low voltage" alarm built in that alerts you to a low voltage situation. It could be a result of a battery failing and they recommend disconnecting the converter, reconnecting it, etc. Should the high pitched sound continue it is either a bad battery or bad converter.

      I do know that Little Guy trailers had a recall on a batch of converters that was supplied to the factory down in Sugarcreek, Ohio and that all defective units were recalled and replaced with WFCO converters. Maybe the high pitched sound is a result of the above?

      Best of luck to you in resolving the issue!

      Elsabe, it may be an emergency cut-off in case of an electrical short, or a generator switch if you have a generator on board. Why not switch it off and see what happens? I'm sure nothing will be damaged by doing so and you may find out what the switch controls.

      Randy - you are absolutely right. The piercing noise doesn't last long enough to flip any breakers. Often times it stops before I can even stand up. I had to find another place to sleep last night. The sound is coming from the ceiling right around the galley area. The RV repair guys have given up. There does seem to be some correlation with rain. My daughter thinks it's an electrical short. At least she was in here with me one of the times it went off last night.

      Joanna, check the negative battery cable where it attaches to the steel frame of the camper. It is common for the connection to corrode and cause the 12 volt system to act up. Make sure the steel frame is clean as well as the cable end. All of the items you mentioned are on the 12 volt system so this may be the problem. Ask for more info if needed.

      Hi,

      My 1999 19 ft Terry by Fleetwood seems to be having some sort of electrical issue. The microwave and plugins are working, the lights have flashed a few times (when switched), and the reader (that tells me how full my tanks and battery are) works some of the time. The fridge, and furnace are un-responsive. The breakers and fuses all look good, and I reset the GFCI.

      I'm supposed to be taking it on the road for a long trip tomorrow so timeliness is preferable, but any help is appreciated.

      Hi Bonnie, this would drive me nuts! I'll bet the noise never happened while the RV repair guys were there as is usually the case. The only suggestion I have is to start turning off breakers when the noise begins to narrow the search down. I'd try the 12 volt panel first. But then, I'd also wager the noise doesn't last long enough to do this. Am I correct? I hope not so we can find the problem.

      Matt, the microwave works on 110 volt AC power, but the slide-out operates on the 12 volt system. Apparently you're getting some power on both 12 volt and 110 volt systems. Have you checked the voltage at the batteries yet? What else is not working properly, outlets, A/C, etc.?

      Hello Matt, check the negative battery cable where it connects to the steel frame of the camper. If it isn't clean it will cause a bad ground and the battery will not charge properly. If this doesn't solve the problem try hooking up a good battery charger--at least 30 amps--to see if the converter is at fault. Ask for more info if needed.

      Hi Demi, is everything else working except the AC, or is all of the power off? If so, try removing all of the fuses except the main and replace the fuses one at a time until you find the one blowing the main fuse. That is, if the main fuse is good. Ask for more info if needed.

      Hi Jeff, not the first time I've heard this happen so don't feel bad. Have you checked the voltage at the batteries yet? You should be getting 13+ volts DC if the power converter is okay. If you have a wall mounted AC thermostat it operates on the 12 volt DC system, as well as the thermostats on the Fridge and H/W heater. You can connect a good charger to the battery(s) and if everything works fine then the converter may be toast. The lights are probably 12 volt but the outlets are 110. Check the GFI outlets and reset them if kicked. Often a power surge will not let the GFIs reset and they'll have to be replaced. Ask for more info if needed.

      Hey Colin and thanks for reading. As for the USB connection, you can probably wire one into the 12 volt fuse panel by either using an empty circuit, or using an already used circuit which isn't used very often. Use any kind of light gage wire--16 would be fine--and if you can't find a 12volt USB receptacle at Lowes or Home Depot, you can always buy a 12 volt auto USB phone charger and wire it into the new line. Hope this helps! :)

      In regards to trailer electricity - I do a lot of bush camping, and I'm looking to run a 12v power supply from the glass fuse panel to the kitchen for charging USB devices such as cell phones, wireless speakers, flashlights etc. How would you install a USB charger from that fuse panel?

      Rolf, I doubt the converter is at fault as it only puts out 12 volts. More than likely the camper is not grounded properly or there is a ;loose ground wire somewhere. Check the 110 volt AC power panel for a loose ground.

      Hi Sharon, the items you mentioned are all using the 12 volt DC system in some capacity or another. In the case of the AC an furnace, they both rely on a thermostat which is powered by 12volts DC even though also use the 11o volt system as well. The water pump is primarily operated by the 12 volt DC system as well.

      Apparently you either have a bad battery ground to the camper frame or your converter is bad. If connecting a good battery charger to the camper battery allows the items to work properly, then a new power converter may be in your near future.

      Joyce, check and the negative battery where it contacts the steel frame of the camper. Clean both cable end and the spot it comes in contact with the frame. A bad ground here may be the cause of your problem. Also, in some cases there is a resistor or breaker box inline from the battery's positive cable to the 12 volt power panel or converter. It should be located not far from the battery box, but these are relatively rare in most cases.

      Hey Dave, if the converter is operating correctly you should be getting a reading of at least 13 volts DC at the battery. There are a couple of things you need to try first. If you haven't cleaned the negative cable where it attaches to the steel frame of the camper then do so and pay particular attention to the area it connects to on the frame.

      A bad ground can cause all sorts of weird stuff to happen. If this doesn't help then try connecting a good battery charger--at least 30 amps--to the battery and if everything works well the trouble is more than likely the power converter.

      Andy, are you referring to the 110 volt outlets as "sockets?" If so, you'll need to replace the outlet and check the power going to it.

      Hi Randy, this is a great forum with helpful information.

      I recently bought a used 2008 Sportsmaster 27pt. When I attempt to run power off the battery, the only thing that will operate is the radio. Nothings else will work. Battery holds charge at 12.6v, it is brand new.

      Please help, thanks.

      Hey Dan, are all of the outlets in the camper dead? Have you checked the main ground in the power panel yet? Sometimes the ground on the end of the shore cable will come loose or corrode. I'd also check the power to all GFCI outlets as they can go out at any time, especially during lightening strike. Feel free to ask for more info if needed.

      I have a 1998 wilderness 26A toy hauler with no power. I'm plugged into house 110v and read good voltage at the main breaker inside the trailer. The breaker checks out fine and power is seen at the other breakers. With all breakers on there is no power at micro, AC, or outlets ( the GFCI was replaced but will not reset ). I'm stumped.

      Hi Darcie, more than likely a wiring connection is loose in the slide-out because of the movement during operation. There should be an access panel for the wiring harness close by--or perhaps--in the slide-out itself.

      David, check the voltage at the battery. It should read at least 13 volts if the power converter is operating properly. Also, try hooking up a good battery charger--not a trickle type--and see if this allows the AC and other lights and stereo to work. Let me know if this helps and if not, feel free to contact me again.

      PlantMan, the damage to the electrical system may not be too severe if the breakers worked properly. The power converter may be damaged but you won't know until you connect to 110 volts and see. I'd turn off all breakers before hooking up to power and, starting with the main, flip the breakers on one at a time. If the breakers don't kick off, then the circuit is probably good. Of course, I cannot vouch for any appliances which were on at the time of the overload.

      At any rate, feel free to contact me again with any further questions you may have. Good luck!

      Randy, I have a 2000 Wilderness Travel Trailer. I'm afraid I have major electrical damage by a mistake. New electrical service was set up at some property I bought. It's a 120 V system and accidentally plugged it into the 220 power...boom/crackle. Not good. Lots of smoke after huge power surge inside, with the microwave, everything going on at once. Flipped breakers of course. Do you think it's major major damage? I've been told that it may be the low voltage transformer is blown. Any help you can give will be appreciated. It's going to be expensive to call in a repairman as our property is located a long distance from him. It may not even be worth repairing if it's likely the whole electrical system is toast. Thanks!

      Hi Pat, have you cleaned the battery cables well, especially the negative battery cable where it attaches to the steel frame of the motorhome. Clean the place on the steel frame as well as the negative cable end it attaches to. A bad ground here will not allow the battery to be charged by the converter. Also, you can connect a good battery charger--not a trickle type--to the battery and if all works well the converter may be at fault. Try cleaning the cables first though. Ask for more info if needed.

      If I understand your question correctly, all the 15A fuses are all on the 12 volt DC panel. Left side is circuit breakers but right side was all the fuses on green board. I don't have access to look at the trailer so I'm going off memory. I believe we did all our testing while running off the battery.

      Randy Godwin 4 months ago from Southern Georgia

      Hello S, what you may be experiencing is probably due to the power converter being on one 15 amp fuse and the power awning on another. As the power awning is powered by the 12 volt system, the power converter is connected to the 110 volt AC system. Are the #1 and #10 fuses in the 12 volt DC panel as opposed to the 110 volt AC fuse/breaker panel?

      Hello - I have a safety question and unable to find correct terminology or confirm whether our trailer has been wired incorrectly. We have discovered while troubleshooting draw issues on our 2014 R-vision travel trailer that two interior lights and power awning are all tied into our fuses in fuse box (#1 and #10) if you remove one of the fuses, the devices still work. Until you remove both fuses #1 and #10, then power is disabled to the two devices. My concern is that we have 15 amp fuses and I believe 15 amp wiring, is this a safety device that these two fuses in the fuse box are somehow tied together and running in parallel? I hope my question makes sense? Is this typical industry standard to do wiring/fuses like this in a travel trailer? It appears the power awning doesn't require 30 amps so I'm confused why lights are not on for example fuse #1 and power awning on fuse #10? We worry because of this setup, the fuses will not trip properly is there is overload beyond 15 amps? Unfortunately the mfgr is out of business and no available for support. Dealer wants to charge labor to look into this. We do have extended warranty but I'm not sure how I would utilize it for this. I would appreciate any advice or suggestions on how to ensure this is OK. Thanks!

      Greg, I wish there was an easier way to find such a short, but usually it's just trial and error. You can turn off all of the 110 breakers and then turn them on one at a time until the short shows on a voltmeter. This way you can narrow down the guilty circuit and the appliances or outlets it powers. Good luck and feel free to ask for more info if you think I can help.

      I have a 13 year old Sprinter pull trailer with an electircal short somewhere. As we were extending the slides, the hydraulic pump stopped running, and a voltage check showed the reading all over the map. Started to get zapped by touching the frame, and other symptoms: The CFL bulb in the 110V lamp over table burns dimly, etc. So, there's a 110 hot lead shorted to the frame. Is thaer any more efficient means of localizing it than just crawling around and trying to inspect wires in close proximity to the frame? The closer one gets to the point of the short with one meter probe on the frame and one in contackt with the wire inside the insulatoin, the lower the voltage will read, correct? Is there a logical place to start this process ?

      Hi Mark, Check the voltage at the battery and see if you're not getting at least 13 volts with the lights on or other 12 volt items. I assume you've checked the converter breaker already. If the "electrician" wired the 230 outlet normally it would have immediately tripped the main breaker because of the dead short. It may have fried the converter but before you buy a new one try a few things.

      Be sure the negative ground cable is clean where it connects to the steel frame of the camper. Often a direct short affects the grounds as well as other connections. As a last resort, turn the converter breaker off in the 110 volt power panel and connect a good battery charger--not a trickle type--to the battery(s) and if everything operates normally a new converter is needed. Hope this info helps you with your problem.

      If my advice doesn't help I'd appreciate you telling me what the problem was. Other RV owners may benefit from your experience. Thanks!

      Richard, I'm not familiar with your model of camper so it's difficult to advise you on your furnace problem. Just wondering, does your AC have manual controls or does it have a wall mount thermostat? Often both AC and furnace use the same thermostat. If your AC doesn't use a wall mount thermostat it may control the heat from the manual controls. If so, it will have a heat control marking on the ceiling assembly.

      Henry, turn all of the breakers off in the 110 volt power panel except for the main breaker. Plug the camper into shore power and then turn on the breakers one at a time until you find the one causing the short. You can then eliminate everything on the circuit except the item causing the short.

We put in the correct 110v breaker. But now everything works except one breaker in the trailer. it controls the lights,sink pump,radio, and i believe the fridge. 15 amp. When you turn it on It trips everything. I noticed it has some type of resister? Or relay from the wiring to the breaker. Only one that has it. Question is what is that thing?

      So I'm gonna try and new cord, and if this is not the case... is there anywhere else other than the fuse box that I should be looking for power sources?

      Jon, it appears there's a short either in the outlet or the cord. Try tuning off all of the 110 volt breakers/ fuses and plug the cord in. If no smoke appears, then turn on the main first and the other 110 volt circuits one at a time until you find the circuit causing the short. You may someone to watch for the smoke while you turn on the breakers/fuses. There may be something on that circuit--either wired or plugged into--causing the short.

      Let me know if you have further problems and I'd pleased to learn what you found out the problem was.

      Hi Jody, have you cleaned the negative battery cable where it attaches to the steel frame of the camper yet? If not, try this first and see if it makes a difference. If you suspect the power converter of being bad then turn off the converter breaker and attach a good battery charger--not a trickle type--to the battery(s) to see everything works properly. If so, the converter is at fault. Ask for more info if needed.

      Hey man. How goes it? Got a 2003 Forrest River "Wildwood" bumper pull. Had it plugged up at home. Everything worked. Got to campsite. Plugged in. Nothing. Switched off breakers inside and lights came on for a second and dimmed off. Flipped breakers back on and the microwave beeped. Microwave works. Flipped breakers back off and lights came on for a second and dimmed off. Checked fuses. They seem ok. What do you think?

      Hi Randy,

      I have a 1973 Holiday 16 foot camper (model 17)

      today, we had a blackout due to the weather which caused our house and our camper (which was plugged into the side of the house, where we were getting power) to turn off.

      I came in and about an hour after the power kicked back on.

      SO, I went back out to the camper and it had nothing.

      I then went and re plugged the cord back in another plug-in. (I also plugged other things into the wall and it worked) and the camper still didnt kick back in.

      Finally, I checked the fuses they dont look burnt out... and when I tried to pull the cord out of the camper it started smoking a small bit.

      NOW, I cant get anything at all. Randy, Can you maybe assist me with what you think is the issue?

      Hello Jay, have you checked to see if there's a relay/fuse inline on the positive cable--usually mounted to the frame of elsewhere--going back to the converter? Some campers have one and some do not. Others have reported this being the problem with their 12 volt system and they had to either clean it or replace it to fix the problem.

      Feel free to ask for more info if needed.

      2011 Wildwood, new batteries, rated at 650 c.c.a., load tested at 700 c.c.a. Cleaned and checked all battery connections twice, made new ground connection to frame. The converter will run all the 12 volt system and still show full battery power. However when I unplug the 120 volt power supply the battery shows less than full voltage. I can turn on one higher draw item such as the water pump and it will work for a while. If I add a couple lights the 12 volt system shuts down completely. When I plug it in again everything works perfectly so it can't be the converter or a fuse. (I checked all the fuses and breakers too.) The converter has been keeping the batteries charged. This problem developed since I had the batteries changed a month ago. It was working ok then, just weak batteries. It has been plugged in continuously for the last month.

      Why don't I have any 12 volt power without the converter plugged in?

      Hello Dennis, this is the first time I've encountered this problem from anyone. I do know an absorption fridge--like most in RVs--won't work if they're unlevel, but not the DC system.

      The only thing I can suggest it when the camper is level and the DC works properly, is to move the converter and the wires around as well as the 12 volt fuse panel and any other part of the system you can to see if the problem occurs.

      Sorry I cannot help you further, but I'd be pleased if you returned and related what the cause of the problem was. Have you tried turning off the converter breaker and using a good battery charger to see if the problem is in the converter?

      Bill, in that case it wouldn't be the converter at fault. I assume the batteries are fine and well topped up with fluid so it has to be a bad ground or a short in the wiring somewhere.

      Hello Larry, when you attached the negative cable to the battery it is common for it to spark as you simply completed the circuit by doing so. You should be receiving at least 13 volts from the converter when measured at the batteries. Be sure to clean both the positive and negative battery connections, especially the negative cable where it attaches to the steel frame and the frame connective point itself.

      Hi Randy great forum! I found you after I ran into my dilemma,(not that you were lost)

      I replaced my old converter, it was only putting out 11.9 volts. The new one is putting out 14.6 volts, so far so good. But ..... when I was attaching the neg battery cable to the battery (I had already attached the pos) the neg cable sparked as I touched it to the neg battery post. Is this normal ? My shore power 120 volts was not connected. The voltage at the disconnected neg cable (which is grounded to the trailer frame) is the same as my batteries 12.75 volts. ( I put the pos side of my meter on the neg cable and the neg side of my meter on the neg battery post) Is this normal back feed until the neg ground is complete? Is it OK to connect the neg cable to the neg battery post? If not, what might be going on ? Thanks for any help you can offer.

      Wendy, if the microwave and oven are on the same circuit there may be a bad connection at one of the outlets on the same circuit. I'd start by checking the outlets in the kitchen. If you have a GFI outlet in the kitchen it could be bad and preventing the power to stop at that outlet. Hope this info helps.

      The battery is probably at fault, Dave. First clean the negative battery cable where it attaches to the steel frame and the frame itself. Also, check the battery(s) fluid level as a low level will prevent the battery from holding a charge. If this fails to work then a new battery may be in your future.

      Randy Godwin 8 months ago from Southern Georgia

      Hi Sue, have checked the power converter yet? The 12 volt system also controls the thermostats in the fridge and in the water heater. The converter also keeps the batteries charged in the camper as well as the lights and vent fans and sometimes the AC thermostats.

      It could also be a bad ground on the negative battery cable where it attaches to the steel frame of the camper. This cable is notorious for getting rusty and causing a bad ground. Also check the positive cable going back to the power panel as there's sometimes a relay mounted in-line near the battery box. These can go bad too.

      If the converter is working properly you should get a reading of at least 13 volts at the battery. I still suspect the converter though. Feel free to ask for more info if needed. :)

      Hi , I was wondering if you could give me some ideas on wiring. We have a 2003 Mobile Scout SunnyBrook 30 ft travel trailer. Every thing works on electric but not so much on propane. We bought a new battery but no power to the hot water heater and the lights (breaks turn signals running lights). all messed up. But in the camper the inside lights work . Somebody said ground wire. but wouldn't it mess up all the lights. If we have auto lights on in the truck the break lights do not work, but they will if we turn off the auto head lights in the truck. If we take a wire directly from the battery to the hot water heater it will start right up. RV place said our Truck was wired right.And works with our horse trailer. we checked the fuses all are good. any ideas . Wish i could find a diagram of how it is wired. Any ideas would be greatly appreciated.And the battery has to be recharged 2 times a day with just the frig. running . something is really pulling the power.Oh and it will not recharge the battery when plugged in to the truck going down the road. Thanks.

      Hi Tommy, you can follow the pigtail connecting to shore power, it connects to the main power panel inside the camper. There's more than likely a breaker/fuse tripped and it could be the power converter breaker/fuse. The fridge thermostat is controlled by the 12 volt system as well. Be sure to check or reset all GFI outlets--usually anywhere you have water nearby, kitchen, bath, etc. to be sure they aren't tripped. Let me know if this info helps or not.

      Scott, it could be either the trailer or the campground hookup, but you should still check the grounds in the power panel for loose connections as when you are touching the camper you're acting as a ground.

      If you weren't standing on bare or damp ground, or were wearing shoes you may not have been grounding the camper at you or your friends home.

      Hi Thomas, have you tried turning off the breaker/fuse which controls the power converter? I'd turn off all the 110 volt breakers except for the main, then slowly turn on the circuit breakers to see if there's a short on one of the circuits causing the problem. This may narrow down the problem somewhat.

      I assume you've reset the GFI outlets as they may have tripped when you grounded the camper by touching it. Also be sure and clean the negative cable of the battery(s) where it connects to the steel frame. If this doesn't help then let me know and we'll go from there.

      Cindy, did you clean the negative cable where it is attached to the steel frame of the camper? If not, try cleaning the negative cable end and also the spot on the frame itself. A bad ground will cause all sorts of problems in a 12 volt system and a corroded negative cable is often the culprit.

      There may also be a fuse/relay located in-line on the positive battery cable going to the 12 volt power panel. This fuse/relay--which you may or may not have--should be near to the battery compartment. Feel free to ask for more info.

      I have a 1995 Kit Companion and have run into some electrical issues. It started with the sudden loss of 12v power. One minute it was fine and then nothing, no dimming, just nothing. First thought was "converter", but testing it with an Ohms meter, and it appears fine. The real head scratcher is, ( I have power coming from the wire connected to the NEGATIVE post of the battery. Before you think, reverse polarity, this is a double 12v system with the positive connected to the positive, and the negative to the negative. There is power from the positive side as well!

      At one point we disconnected the negative cable, and for a moment all was right, but once we reconnected the cable it when back to being positively charged.

      You may have to run temporary wiring before finding out where the wires go from the breaker, Gordon. If things work correctly, then you can think about snaking new wires in some manner. Sorry I can't furnish you with a wiring diagram as it would be invaluable. I run into this more often than you'd imagine as many older RVs usually didn't supply a diagram.

      Gordon, there's obviously a short in the GFI connection. The converter should not affect the 110 volt breaker the GFI circuits are connected to. Check the ground wires going to the GFI circuit as one is probably touching a hot wire somewhere in the breaker panel. Feel free to ask for more info if needed.

      Thanks for the speedy reply, I haven't checked shore power but there's a glitch there too, the camper is a 67 and the shore power connection is a pretty ancient 3 prong plug that I have yet to find an adapter for.

      I just got this rig and the PO assured me all lights work but they didn't have a clue where power cord was. It was a mirical we ever found the jack stands & crank among the mountain of 'stuff' they have.

      Anyhow lights fire up (in reverse) I have no doubt they work on shore power.

      The 7 pin works on my other camper but on this one I get this glitgh. I have tested with a test light and all is as it should be. I also have a Reese plug tester and that shows AOK, I do not however have a meter.

      Was wondering if I switch the black 12 volt wire to the middle connection where yellow (back up) connection is and vise versa would that work or blow my brand new battery.

      I will check the 12 volt system in the morning.

      I think I goofed trying to explain my set-up LOL

      the camper is next to the house, the house has 110 panel I have one Free outlet at the moment that is on a double breaker (so 220) for my stove(this is the outlet I'm using at the moment for the past 2 weeks) but only rated for 15A so yeah I realise it is not enough for the AC, I have a spare slot in the panel for a double breaker that I could dedicate to the trailer (not sure when my electrician would be avail.) I can fiddle with re-wiring just redid my boat trailer, but I draw the line at the electrical panel... OK so I'll set that one aside for now... the 12 volt system, the trailer hitch has a space for 2x large batteries that's what I went and got, I haven't got the gas on I am going to go buy 2x tanks tomorrow or saturday so I am unsure what load the gas will be taking over... as it is when I installed the 2 batteries basically a 24v system I followed the set-up for them and all I got was lights, nothing else worked. I checked the breakers in the trailer and checked that the batteries were at full capacity both tested at 13v (2 weeks ago) then I plugged in the trailer to the house (on the only outlet I had available) and got the fridge, water pump and microwave going, a little TV and a couple of floor fans all running smoothly. n the power (my assumption was that the main power would charge up the batteries at same time. )

      We did have a couple of bg electrical whopping storms a few days ago but I think it is somewhere between the batteries and the trailer that not working, honestly I don't know where the converter is or I would've tested it. I am on limited internet (went over my datea) so crawling at the speed of a snail right now normally I would google all the schematics and youtube to find out all the little details. 3 more days before I get the speed back... So I will go have a look in the morning and start from the batteries work my way inside. Thank you will let you know what I find. (if anything)

      Hi Theresa, I'll help you as much as I can without actually being there. Bear with me because sometimes I do not have access to comments for several hours and the same for my own comments.

      The first question is why do you use a 15 amp 220 outlet instead of replacing the breaker with a larger size. I assume you have two ACs since you have a 220 pigtail plug. If the wiring is large enough--probably 10-2 would do--you can simply replace the breaker.

      You presently do not have enough amps to run the AC from the present power source even if it is in perfect running condition

      As for the 12 volt DC problem, have you checked the power converter to see if it's keeping the batteries fully charged. Also, make sure the battery ground cable is clean where it attaches to the steel frame of the trailer. Also clean the frame where the ground cable attaches. A bad ground here will cause all sorts of problems.

      Too, if the fridge is a gas/electric model the thermostat is powered by the 12 volt system as is the AC if you have a wall mounted thermostat.

      I hope I covered your questions but if not, please feel free to shoot me few more.

      Hi Randy, so much good info on here thanks!

      I have a 2005 Fleetwood Pioneer BP travel trailer that I got at auction, so no books or any background info. So far it seems pretty sound.

      Now I'm readying for visitors coming to stay with us on the farm.

      I have it in a 15A/220v outlet (of course the big AC trip the breaker when I tried it LOL) So we put an X on using it for the moment (the AC that is) ... OK now I got 2x new deep charge batteries for it a few weeks ago and hooked them up, all they seemed to be able to power were the lights! Maybe I hooked the batteries wrong?

      2nd yesterday an alarm started, high pitched LOUD ... upon investigating (and ripping out out all 3 D batteries out of the smoke and CO2 detectors (which I'm replacing with new one tomorrow) the beep still came back, found a little red light on a panel said: Low Power,

      Well I thought when you were plugged into the main power that the batteries re-charged themselves? So again either I did not hook them up right or it's something else ... I was thinking of adding a double breaker on my house 110 panel and running a line out jut for the trailer would love to be able to run the AC (if it works)... Alternatively I do have a generator not sure how long it would have to run to keep the fridge (apartment size going?) 2x small fans and a TV and some lights...

      I'll gladly look up any info on panels, appliances and o on that you might need to give an answer. I have tomorrow to run around and try and get some of the problems fixed, my guests arrive on Saturday but I can still work on it after, just would like the alarm to stop beeping when they are here and trying to sleep LOL... unlike a lot of the above comments people pulling fuses or shutting breakers I need to have my unit going! (it's breakers in the panel and I did turn off the AC breaker)

      Really hoping you can help me de-muddle even if it's just to know what and how to ask retailers for what I need!

      Thank you

      Hi Chris, sounds like a dead short of some kind. Have you checked the pigtail where it connects to the breaker panel? If you have to you can make a temporary pigtail out of 12-2 wire to see if the pigtail is at fault. Ask for info if needed.

      Hey Randy!

      I haves 1972 Shasta Starflyte with a single 15 amp breaker but whenever I plug the trailer into the receptacle at the house the breaker in my house (15 amp also) trips. I've even un installed every light fixture and receptacle and wire nutted each wire individually and it still happens when I plug it in.

      I have no clue where else to start looking before I have to tear back into the walls and am hoping you might have an idea.

      Thanks!

      Hello Abe, first I would turn off the breaker/fuse which controls power to the converter. Then replace the blown 30 amp fuses and see if they blow again. If not, the converter is shorted out and needs replacing.

      If they still blow then remove all of the smaller fuses--other than the two 30 amp fuses-- and try again. If the 30 amp fuses do not blow then replace the smaller fuses until you find the circuit causing the overload. Ask for more help if needed.

      Randy, I do not have any 12v power from my trailer plug or my battery on my travel trailer. I believe the previous owner had switched the positive and negative battery cables around when they tried to hook it up. I have two 30 amp fuses that are labbled "battery", but they keep popping. Im not sure of the exact time that they popped, but its happened twice so far. Where should I start?!!!

      Hello John, you need to find the 12 volt power panel to see if a fuse or breaker is tripped. The 12 volt and 110 volt power/breaker panels are usually near where the 110 volt power shore connection exits the camper.

      Hi Bobby, if you aren't connected to a 110 volt power supply -- and haven't been in a long time--how are you keeping the battery charged to peak? Unless there's fuse/relay mounted in-line from the positive battery cable to the 12 volt panel, I'm not aware of any place other than the 12 volt panel where there's junction box. Some campers have the fuse/relay and do not.

      Thank you Randy. I traced the wiring to the first light. Turns out there was a bad switch that controlled the whole circuit underneath the cabinet (not sure why it's there since every light has it's own switch). Once I eliminated the switch, all the lights started working!

      Brian, I'd check the first light in the circuit if you know which it is and look especially at the ground and positive wires where they connect to the fixture. You really need a 12 volt test light or you can use a multimeter if you have one. Hope this helps!

      All the other DC circuits off of the panel are working. The slides work, the lights in the front room and bathrooms work. The vent fan and light from the hood work as well. It's just one circuit that has four lights down the middle of the camper that are not working. I have 13.2 volts at the DC input of the panel. I have tightened all the ground wires on the grounding bar. Could there be some component I may not be aware of between the panel and the first light?

The generator stopped putting 110 volts in the camper but shore power was okay. Several weeks later, the shore power quit too. I checked it out then plugged the shore power back in and was surprised to get a great electrical flash arc at my home plug receptacle. Huh, I don't know. I could not locate the transfer switch and couldn't find a repair manual nor diagram of the system...? Any ideas beside dropping it off at the expensive repair shops?

      Hi Rebecca, apparently the AC is overloading the breaker for some reason. It could be something as simple as dirty coils causing the compressor to overheat thereby tripping the breaker--which using a good coil cleaner should fix the problem-- or the worst case scenario is a bad compressor causing the breaker to trip. In this particular case it would better to replace the old unit rather that having a new compressor installed. Usually this is cost prohibitive when the labor is added in. Ask for more info if needed.

      Sorry about the delay answering you Rebecca. The comment program on this site is making comments difficult to respond to. Hopefully they'll get it fixed soon. :)

All accessories work perfect with the generator running, but as soon as the generator shuts off I lose power to everything in trailer. I have checked the converter and it shows 5.5 volts along with the 12volt side of the fuse panel. I'm checking grounds and nothing is standing out. Do you have any other ideas? I have also checked the gfi and that appears ok also? Kinda at a loss. Thank you in advance.

      Hey Wayne, do I understand correctly that you have power at all of the breakers in the 110 volt power panel? If so, I'd check all of the non-working outlets for a loose or burnt wire. An electric heater pulls lots of amps so there may be wire not making contact in one of the outlets. They--the non-working outlets--are probably on one circuit.

      Randy, the dealership confirmed that it was the main power wire running from the back of the converter to the junction box where the 30A pigtail connects to the trailer that was shorting out. They had to cut the underbelly and replace the wire and found that the wire had been pinched between the frame and the underbelly and had worn through the plastic coating causing the short. It was due to in attention during manufacturing and not a failure of the wire.

      Cynthia, did you discuss your needs with a Lowe's employee? I'm sure they have a generator that will do the job. Sometimes you can buy a good generator used on a motorhome which has been junked. Most of the time these generators have been used very little and will provide more than enough power for your needs as well as being quieter than most standard generators.

      Kyle, I didn't realize your converter was wired directly from the pigtail. Most converters get their 110 volt AC power from a breaker in the 110 volt breaker panel and with all the breakers turned off I couldn't see how the converter was causing the house breaker to trip. I've learned something myself from your problem.

      I'm not sure how your wiring is routed but it seems strange that you can't access the wiring without having to remove the underpinning. Let me know what you find out from the repairman if you don't mind.

      Randy, I should further explain that I had someone test the cord/pigtail and it seemed OK. He thinks that the short is in the orange wire from the pigtail to the converter which is in the underbelly. I'm not sure why it would go bad but is it wired direct to the converter? Being enclosed I can't see if it connects to anything else between the junction box and the converter. At this point I'm going to take it to a dealer to have a technician fix the problem. Thanks for your help. I will post the final outcome when known.

    • profile image

      Kyle 11 months ago

      We just bypassed the power cord and put power directly to the converter like you suggested and the breaker did not trip and we confirmed using the meter that it is the source of the short. I'm assuming I need to replace the entire wire running from the converter back to the 30A plug junction box which is contained within the metal cord box. The trailer has an enclosed underbelly so do you know if I can just pull the new wire by attaching it to the original or does the underbelly need to be removed? I'm concerned about snagging on the furnace ducting. Any idea on why the wire would be shorting out in the first place?

    • Randy Godwin profile image

      Randy Godwin 11 months ago from Southern Georgia

      Kyle, you can check the pigtail for a short by using a multimeter set on ohms if you know how. If you don't then let me know and I'll describe the process for you. If nothing else you can replace the male plug on the pigtail as they sometimes short out.

      Also you can run another wire from the 110 volt breaker panel where the pigtail connects--12-2 or 14-2 would work fine with an ordinary plug on the end and it doesn't have to be very long because you can use an extension cord to hook to it. If it kicks the breaker then you have other problems. If not, then the pigtail is the culprit.

      I found where the pigtails connect to the trailer and they are tight. I also checked the junction box under the hitch and pulled out the converter. All connections are tight. I'm wondering if it might be the cord itself or the plug end. Unfortunately the cord stores in a metal box welded to the under carriage and the underbelly of the trailer is enclosed so I don't want to start taking off all of that if it can be avoided. I'm at a loss as to what would be causing it to short out at this point.

      Hello Kyle. have you tried another outlet other than the one you're presently using from the house? If so, and the same thing happens, then check where the pigtail wires are connected to the main breaker panel. Sometimes the pigtail comes loose at this point especially if the pigtail has been stretched or pulled at some point.

      Also, it isn't uncommon for a main breaker to go bad but this doesn't sound like it's the case. Feel free to ask for more info and I'd appreciate it if you'd let me know what the problem was if you find it so I may be able to help others with similar problems. :)

      Hello John, if you had the camper hooked up to whatever you were towing it with, the jacks may have been using the tow vehicle battery to operate the jacks. In this case, the converter may not be charging the camper batteries properly, but the tow vehicle battery is getting charged by the alternator and enabling the jacks to work. Also, the tow vehicle may be charging the camper batteries.

      You need to check the voltage at the camper batteries to see if the converter is putting out at least 13 volts. If not, you may have a bad converter. Ask for more info if you need it.

      I have a 2005 Jayco HD. we went camping over memorial weekend. When we were going to leave and when I wanted to raise the jacks they would not come up. I did manage to check out fuses all were good. I did release some of the power on the release buttons on the hydraulic unit. Enough to take all jacks and move them to the horizontal position to get home. I stop down the road to get some supper and when I started up the rv the jacks kick in and they returned to the normal up position. I looked over the manual book and could not find any troubleshooting technics to check out. Some reason it reset the unit, control system somehow. Do you have any knowledge on resetting the hydraulic unit in case this happens again. Also I have returned all hydraulic power lifts to there original position. Also have check to see if they all work properly and they do.

      Hi Steve, have you checked the voltage at the batteries? If the converter is operating properly you should get a reading of at least 13 volts DC at the batteries. Check to see if there is a relay on the positive battery cable going back to the converter. Some camper trailers have such a relay while others do not. If you have a relay then check to see if the voltage is getting past the relay. If not, the relay is bad.

      Ask for more info if needed. :)

      Tom, is the converter on a circuit by itself? If so, it's getting 110 volts if all of the 12 volt DC items are operating correctly. have you checked the end of the pigtail where it connects to the 110 volt breaker box yet? If you are getting 110 volts there then it may be a bad ground. You may want to disconnect the power and tighten all of the connections if the 110 volt breaker panel, especially the ground wires. Hope this helps you but if not we'll try something else.

      Brennan, it is most likely the converter and not the outlets causing the problem. More than likely when the converter was subjected to reverse polarity it damaged the converter in some manner which is causing it to short out. A new converter may be called for unless you can have the old one checked out by an electrical repair guy.

      Thanks for the reply Randy. I should have mentioned that I did that exact test last night and determined that it was the converter that was tripping the house GFI.

      Knowing that it's most likely the converter, should I start testing the receptacles, lights and switches for a short? The lights and switches seem to work fine, but I haven't checked the receptacles yet. However, if there was short somewhere would the converter respond by pulling too many amps? Or should I assume that the converter is trying to pull too many amps to charge the 12volt battery?

      Your thoughts are greatly appreciated?

      Thanks again,

      Brennan

      Randy Godwin 12 months ago

      Hi Brennan, the easiest way to find out what circuit is causing the GFI to trip is to turn off all the breakers except the main in the 110volt AC breaker panel and then reset the GFI. It shouldn't trip the GFI if everything is normal. You can then start turning the 110 volt breakers back on one at a time until you find which circuit is kicking the GFI breaker. I'd suggest turning the converter breaker on first to see if the converter is indeed the culprit.

      You can do the same with the 12 volt breakers or fuses if you have them if the 110 volt check doesn't solve the problem. Feel free to ask for more info if needed. Thanks for the question and good luck with your repairs. :)

      Mr. Godwin,

      Thanks for the articles on RV electrical systems and converters. We just purchased a 1994 Kit Road Ranger. Here is my problem I'm trying to trouble shoot:

      When I plug the trailer into the house it throws the 20amp house GFI it is plugged into. The house is new, the house GFI is new, the extension cord is 25' - 14ga/15amp rated and there are no other loads on the house circuit. The 12volt systems in the trailer work (lights, fan, etc) and there is nothing plugged into any of the 110 volt trailer reciprocals.

      I haven't had time to check for loose connections at the trailer recepticals, but after checking those later today if the problem persist I'm assuming that I have a bad converter that is pulling way too many amp. Thoughts? Am I on the right track?

      Additionally, my father-in-law, who we bought the trailer from, had the trailer plugged into his house with a 150' 16ga extension cord. Additionally, he installed a new battery a couple months back and crossed the wires for about 1 week (positive to the negative and vice versa). Despite his mental midgetness no house breakers were thrown at his house. I'm at a loss at this point.

      Thanks,

      Brennan

      Hi Jeff, all of the items not working depend on the 12 volt DC system. Is the power converter keeping the battery(s) charged fully? And what is on the circuits blowing the 40 amp fuses? A bit more info may enable me to help you with the problem.

      Hello Randy, I'm in need of some quick advice.. I have a 2011 keystone Summerland TRAVEL trailer. My issue is after it sat for the past winter my electrical system is acting up. My lights worked and I extended my side-out. Also the Water pump worked. Then..... I hooked it up to the city water supply, also attempting the hot water heater. The water system flowed nicely but the water heater (electric switch) would not ignite. Also my radio and fridge will not work. The trailer was hooked up to the home electric at the time. I checked the breakers which were fine and the the fuses.. both 40amp fuses were blown and I thought I had my problem solved but when I replaced them with new fuses, the lights dimmed and it is lacking in power. What could be my issue??? Fried a fuse in my hand In The process ..

      Hey Carrie, you'll have to replace the GFI outlet more than likely. The other outlet is probably on the same circuit as the GFI outlet causing it to be bad also. This is a common problem both in RVs and home electrical systems. When you replace the GFI outlet the other one should work also.

      Feel free to ask for more info if this doesn't correct the problem. Thanks for reading and the question. :)

      Hi Mike, and thanks for your time and question. I don't know type or make of trailer you have but the problem may be in the slide-out wiring connector. You can usually access this connection by removing a panel or the molding near the switch. The wiring may also be crimped as it has to move with the slide-out. Hope this helps you solve the problem but feel free to ask more questions if needed. :)

      We just took our trailer out of winter storage. Hooked the 2 6 volt batteries back up (properly) and every time I move the slide out or in a few inches the lights flicker and I lose power. Everything works fine with the 110 Vac connected. I un hooked the batteries and I get 13.7 v across the converter (plugged into 110 Vac). I checked the battery wires and the is 13.6 V there as well. Both batteries read 6.3 and 6.4 volts. They seem to be charged and seems that they are being charged. I checked the ground at the frame. Removed it and made sure it was ok and tight. Un plug the 110 Vac and try and move the slide and it cuts out. I'm stumped....lol

      Hi Karen and sorry to be so long responding but I was away all day. GFI receptacles are notorious for causing problems, especially if they've been tripped repeatedly over the years. If you've checked everything with a multimeter to be sure there isn't a short, I'd try changing the GFI.

      Reading my response above, I realized you may have been referring to a GFI at a campground. LOL! Obviously you cannot replace it, so more than likely there's a short in the camper. You should be able to find it using a multimeter. Turn off all of the circuits in the main breaker panel and turn them back on one at a time after checking it out.

      Feel free to ask more questions. :)

      Hi Patrick, the converter should be on a 110 volt AC circuit by itself with the output connected to the battery and then on to the 12 volt DC fuse block. Both the fuse block and the battery should be grounded to the steel frame of the trailer to complete the 12 volt system. I don't see a need for a switch to separately or simultaneously operate both AC and DC systems. I hope this helps you out with the set up. If not, feel free to ask for more info. Thanks for reading and the questions. :)

      Randy:

      I have a Wells Cargo Motorcycle trailer that is also converted to be used for camping with bunks, fans, stereo, etc. I bought the trailer used and it had been broken into previously and most of the good stuff taken. Previous to that the trailer had three power sources, An AC connection, an intereior deep cycle marine battery (and charger) that powered all the interior 12V lights and appliances and a small exterior 12v battery that powered the trailer emergency brakes and some exterior lighting. I put a new converter and multi-fuse block in and wired all the 12v stuff to the fuse block with appropriate fuses. I would like to be able to run the 12v stuff off a deep cycle 12V battery when 110/120v is not available. Now my question: Could you explain how I can safely wire the deep cycle battery in to the fuse block so as not to cause damage to the converter, or cause damage to the battery when connected to an AC source. I am guessing that I may need to run a switch so I can switch between the two power sources, but I am wondering if this is the most foolproof way to prevent damage in case of a SNAFU. I would appreciate your advice.

      Hi Joe, are you sure the fuse blown was to the slide-out, or are you simply guessing? If you're sure it's the correct fuse then the motor must be overloading and causing the fuse to blow. That or it's a dead short in the wiring causing the problem.

      If you're not sure the fuse controls the slide-out you may be able to jump the current in the switch panel for the slide-out controls. First check the voltage of the slide-out panel switches with a multimeter to be sure the power isn't getting to the switch in question before going further.

      Feel free to ask for more info if needed. :)

      Hi, i recently purchased a used 2002 jayco designer 5th wheel 32rlts. We got it to its spot and started to figure out how to work all the pop outs and such. When we attempted to use the electric switch for the pop out it did nothing. All of the other electrical components worked, ie lights. Microwave etc. We looked in the fuse box. And in the 12 position, we noticed it was missing a 20 v fuse. We used one of the existing 20 v fuses and tried again. It sparked immediatley and blew the fuse. We tried a 30 or 35 v fuse and it also blew. I then took the pop out power switches off the wall and they appear, on a simple visual check, to be wired correctly. Can you offer any advice on where to start trying to find some help with this issue? One of the pop outs its not all the way closed, so we would like to figure this out before snow starts falling. Any help would be great. Thanks ahead of time.

      Hi Randy,

      Sorry for the delay (again,) got laid up with a torn rotator cuff.

      I was completely stumped by my electrical gremlin, but took a head on approach over the past few days. Checked the battery disconnect relay, and no power in either position. Then I checked the fuse panel by the convertor, and although I still had 12V at the panel, nothing was operating. While string at it dumbfounded, I decided to check the amperage that was coming through the fuses. Microamps! I ordered the battery disconnect relay and installed it today. Sure enough, all of the 12V lights and accessories are now working on the house batteries, but not on shoreline. I will be ordering a replacement convertor tomorrow. I think we were both under the impression that it had to be a ground because it was highly unlikely that both the convertor and battery disconnect relay had gone bad. It's a 23 year old RV and has the dreaded Magnetek 6345 convertor. I guess sometimes everything can go at once.

      nbbrown--First you need to clean the negative battery cable end where it connects to the steel frame and the spot where it connects to. Then check the voltage at the battery where you should get at least 13 volts when a 12 volt item is operating. You may also need to check the battery after disconnecting the cables to ascertain if the battery is good or bad. A bad battery will not furnish enough amperage to operate all of the 12 volt items on board. Let me know if this doesn't solve the problem. :)

      Hi Randy

      I have a 2010 spree travel trailer. My problem is that everything works fine when hooked to 110 or a generator but when I disconnect from either one to automatically switch to 12 volt, the power will shut off then the fan at the breaker box will come on then after a few seconds a click will sound and the 12 volt power will come on then it will shut off again. This will continue on and on until I switch back to the generator. It will keep the refrigerator running but as soon as I turn a light on it will click off the power then on then off etc. What do you think the problem is? .

      Hi Shannon, the only option you have to increase the amperage is to convert to a 5o amp system. However, breakers go bad over the years especially when one lives in an area with frequent power surges or deficits. It may be worth trying to replace the breakers which trip the most often before changing the entire system. Thanks for the question. :)

      Shannon 23 months ago

      I have a 1981 (?) Holiday Rambler with apparent electrical issues. This weekend we've had quite a few storms move through the area. It seems that when the power flickers, it trips a breaker, which then will not reset. I live in this thing, so no lights, hot water, etc. really is not an option.

      Aftet reading through as many of your previous posts as possible (on my phone), I've determined that it's probably best to switch out the breaker box and converter.

      So, my question is this. I'm on 30A, can I upgrade so the breakers can better accomodate any overages, say, by at least 5A on each switch, without affecting the 30A load max?

      Both pull a lot of amps but shouldn't cause the GFI to trip so easily unless they are older models pulling more amps than usual. It wouldn't hurt to check the ground wires on these circuits merely to see if they are securely tightened.

      Brutee, Have you tried turning all of the breakers off before plugging the camper into the shore power and then flipping them on one at a time to see which circuit is tripping the GFI? There's apparently a bad ground or short on one of the circuits and you may be able to narrow it down using the ab0ve method.

      I have a 2003 Keystone Sprinter travel trailer. When I connect to a 30 amp GFI power source the GFI consistently trips at the source. Sometimes just hooking up trips the circuit, but I cannot run the AC or microwave without tripping the source GFI. This happens at home or at the campground that provides GFI protected power. Everything works fine on non GFI power.

      Hello again ED, pleased to see you return. This does seem to be a real puzzler, especially since you are getting different voltages from the same lug on the battery disconnect relay. Have you tried disconnecting the power connector from the generator to see if that makes a difference? I assume you've checked the voltage at the relay already so I suppose you've ruled that out, along with a possibly bad relay. You might try jumping the relay to see if it is indeed working properly.

      I also assume you've checked the ground on the generator and in the 12 volt power panel. Just trying to narrow down things you may have already thought of so far. Don't give up yet! :)

      Hi Randy,

      Sorry for taking so long to get back to you. I just did an extensive continuity check on the grounding of the vehicle, and the negative side soes not seem to be an issue. The batteries are charging and the fuse panel is showing 12+ on all circuits, but nothing that runs on 12 volts is running. The two times it came on intermittently had me optimistic that it was a ground issue, but now I'm back to a B+ issue. I'm only reading 3-5 volts at the power connector on the generator, when it should be 12+, but I'm getting 12+ at the power distribution center fuses, and the 120V side is working fine. This confuses me, as both the cable to the generator and the cable to the power distribution center come from the same lug on the battery disconnect relay. I've done years of 12V work on automobiles, but this is an enigma.

      When it rains--or perhaps a garden hose will do the trick instead--and the power goes off, start at the shore hook-up and check the voltage there, Carol. If you're getting power there then go to the main 110 volt power panel and see if get voltage where the pigtail for the shore line connects to the power panel.

      If everything goes off--including the 12 volt lights and vent fans-- I suspect the short will be either shore plug in or the main power panel. Let me what you find and /or ask for more info. :)

      Hi John, this really sounds like a bad ground on the 12 volt battery as the items you mentioned are controlled by the battery and converter. Both the fridge and HW heater thermostats are 12 volts as are the steps. Clean the battery ground where it connects with the camper frame good, both the battery ground and where it contacts the frame. You should get 13+ volts at the battery if the converter is working properly

      Let me know if this doesn't solve the problem and we'll go from there. :)

      no power to ref on rv. Check 110 outlet by ref and there is 110 volts there. Did check the converter and it is giving me 12 volt supply out of converter. It is a two way ref. 110 volt or gas neither one will work. There is no power to control panel inside of camper. Outside by plugin there is a circuit board were you would plug the wire to start the gas. Below this is a junction cannot get any readings here either. They did have a new control board plugged this in and still did not work. Can you tell me where I need to look next. Also the gas on water heater is not working. And the steps will not go back in. They could be on the same circuit but not sure if they are or not.

      Hi George, sorry to respond so late but I had a death in the family yesterday. I haven't had much experience with FEMA trailers, but I can understand how they would operate without a battery.

      I plugged it into the 120 volt (house). When I turn on more than 1 light a painful high pitch ringing/humming happens.

      My poor dog about died. I now know why the covers have holes in them from people hitting the lights trying to get it to stop.

      P.S. the humming is 10X worse when the refrigerator is on and you turn on more than 2 lights.

      Hi John, sounds like the converter is not the problem so this leaves the batteries suspect. Often merely cleaning the battery ground where it is attached to the steel frame--and the spot on the frame itself--will cure all sorts of weird problems with the 12 volt DC system.

      Also, make sure the fluid level in the batteries--if they aren't the sealed variety--isn't too low. The clicking may indicate the batteries are requiring the converter to cycle on and off because they can't hold a charge. This is merely and educated guess, however. Ask for more inf if needed.

      Hi Kathi, you are right about everything but the receptacles and perhaps some of lights use ordinary 110 volt bulbs. If the receptacles do not work then it could be something else. If only the 12 volt items do not work--some lights overhead vent fans fridge and perhaps the AC depending on if you have a wall mount thermostat--the battery is probably at fault.

      Randy,

      We just purchases at 2004 Mallard travel trailer. We pulled it home yesterday and plugged it into the 120 volt (house) to load it up and get the refrigerator cooled. While checking everything out all of a sudden the lights started dimming and the alarm was going off. My husband made sure the propane was off and the heat was turned off. What we had running at this time were the lights, refrigerator, radio and TV. My husband is of course freaking out and saying we will never go camping again...I have be reading through all of your questions/comments above and hope I have the correct determination here...

      1. The lights and receptacles run off the battery.

      2. The converter coverts the land power (or generator) to the battery which will charge the battery to run the lights and receptacles.

      3. Even if your are plugged in to the land power...the battery still runs the lights and the receptacles.

      4. If your battery is not charged properly (or old...ours is dated 2004) then the converter cannot even charge the battery.

      My determination is that we need a new battery.

      Please tell me I am correct.

      Thank you.

      Hi Todd, you will need a 30 amp fuse or circuit breaker box and you can probably get by with using 14 gauge wire for installing the lights and outlets you will require. This goes for the AC also if it's going to be on a circuit by itself. I'd suggest having more outlets than you think you would need while installing them. it's better to have too many than not enough.

      Please ask for more info if you need it, and thanks for the question. :)

      I have a question for you. My husband and I have a 36ft camper. We have been camping many times at campsites, but we would love to go out on my parents' farm. We are trying to figure out what type of battery we will need to run the entire camper for a weekend. We were thinking of purchasing Vmaxtanks Vmaxslr125 AGM Deep Cycle 12v 125ah SLA rechargeable Battery and a Smart Charger to go with it. Would this battery pull everything by itself or would we need an additional one?

      Hey Carl, if it's a cooling fan you shouldn't disconnect it because it is necessary to keep the cooling system operating properly. You should be able to replace it fairly easy and inexpensively as it may be a plug-in fan. Apparently it is drawing too many amps for the converter to keep the battery properly charged because of bad bearings in the fan motor.

      Let me know if I'm either right or wrong in my assessment if you don't mind. :)

      There is a fan on our 2011 Rockwood travel trailer fridge. It runs for 7 second, off 5 seconds, then repeats. It sucks the life out of the battery. Can we disconnect it somehow?

      Yo Mxrx, Are you using a regular extension cord or are you referring to the pigtail on the RV? Using a small extension cord can cause the breaker to kick as it cannot carry enough amps--especially with the AC in operation--without overloading the system.

      After trying a heavy duty 30+ amp extension cord, and if the breaker still kicks off, then get back to me. Thanks for the question. :)

      I am thinking I might need a new converter...What it has now is a 32A-120v/12v-bw6332 the part number is 083208-01-000 Maybe I could update it to Progressive Dynamics (PD9245CV) 45 Amp Power Converter with Charge Wizard.

      Hi I have a 1995 Winnebago warrior and when I plug it in to 120V at a campground or at home it ends up tripping the breaker that I plug it into, it especially happens if you turn on the roof air. I think it might dangerous because the extension cord is quite warm. Its confusing me because its designed to be plugged in to 120V?

      Ed--If the converter is working correctly you should be reading 13+ volts at the battery. However, if none of the 12 volt circuits are working the converter wouldn't be charging the batteries as they would not have a drain on them. Have you checked the ground in the 12 volt fuse panel yet? I cannot think of why the whole system is inoperable unless the main fuse is blown or a bad ground is causing the problem. Does your converter have a ground wire?

    • profile image

      Ed 2 years ago

      Hi Randy,

      I'm getting 12V at the fuses of the converter, as well as reading 12V at the fuses with different ground points. Good 12V at the batteries. No power to the 12 volt system (lights, fridge, etc) at all from either. Thinking about what you said in your last post, I should see 12V at the battery terminals with the batteries disconnected and the shoreline connected, correct? If so, would this just indicate that the battery charger is working, or that the whole system is working?

      Randy Godwin 2 years ago from Southern Georgia

      Hey Ed,

      If I'm understanding you correctly then you are getting power from the converter but not at the batteries? You didn't say in your last post whether you had checked the voltage at the batteries or not.

      The batteries usually completes the next to last link before the 12 volt DC fuse or breaker panel, with all of the circuits being the last. There may be a break or short from the converter to the batteries. You should be able to track this down if so.

      Don't give up, and as always, let me know if I can further assist you with your problem.

      Randy,

      Thanks for the reply. After you mentioned the ground, it sounded like it would be the answer, especially when I tried starting the generator during one of the periods when the power was on, and had an immediate shutdown of all 12 volt power. I crawled under the RV today, checked the chassis ground connections-all were tight, no rust, not rot through. I cleaned everything with a wire brush and made sure everything was back together nice and tight. No go when I tried throwing the switch. I'm getting a good 12 volts (13-15) at the power converter distribution under the refrigerator when plugged into the shoreline, and even checked a few different ground points successfully, and the house batteries are brand new. Not really sure where to go from here.

      Hello Ed,

      Have you checked the fluid level in the batteries? If the level is low the batteries will not hold a charge properly. Also, you need to clean the negative battery cables where they are bolted to the steel frame and also the frame itself because a bad ground can cause the problem your are presently experiencing.

      If the converter is working properly, you should be getting around 13+ volts at the batteries if checked with a multimeter. Feel free to ask for more info if needed. :)

      Hi Randy,

      I've got a new to me 1992 Winnebago Adventurer. I have an intermittent problem with the 12 volt system. It doesn't work, either on the in house batteries, or on shoreline (110 is fine on shoreline) but if I let it sit (days to weeks), it will eventually get power. My best guess is the battery disconnect relay is bad, and just sitting, it will randomly throw, but I figured that I'd run it by someone with a little more experience in this area.

      Hi James, yes thee should be a battery to ensure proper amperage as several items get power from the 12 volt system. Along with some of the lights, the fridge and sometimes the AC thermostats are powered by this same system.

      When more power than the converter provides is needed the battery keeps the system from tripping the breakers as you've described. Feel free to ask for more info if needed. :)

      I'm an RV newbie. I have a couple questions if you don't mind. We are staying in my father in laws early 2000s River Forest 29 BHS while we have a home built. We are running on shore power. Should I a battery connected? There is no battery connected but looks like there is a spot for one by the Propane tanks in the front. Next problem we are having is that the lights start dimming and the power shuts off...little white box on the floor make an annoying sound. Flip breakers for a while and the power comes back on. I think it has something to do with the water heater element running. I've ordered a new element and anode rod. Are there other things I could check to gets this squared away? I really appreciate your help!

      It should be fine to use the charger with the converter out, and if not, no danger to the system should occur. I do believe the battery provides the charge to the 12 volt breakers or fuses and the converter keeps the battery at optimum charge. I suppose someone may have altered the system otherwise but it is still worth a try.

      I have the converter out at the moment. An electronic engineer was looking at it, but said it was in repairable. Could I try it without the convertor installed or would it need to be installed? Also when it is installed it trips the breaker and blew the stuffings out of a capacitor . thanks

      Hello Josh, the converter usually powers the thermostat on the fridge and some of the lights also. If you have a wall mounted thermostat for the AC and heat, they are also powered by the converter. Have you tried a battery charger in place of the converter to see if this would provide enough power to operate the 12 volt system?

      Hi Mel,

      Have you cleaned the negative battery cable where it is connected to the steel frame of the trailer? If not, try using some sandpaper on the frame and on the connection itself to ensure a good ground from the battery to the breaker box and converter. This a common problem I encounter often from older models of campers. Usually not a big problem. :)

      Hi Randy. Just bought a used 98 Forest River Flagstaff 21RB Travel Trailer. Everything works fine while plugged in and running on AC current. However when unplugged I get nothing. Deep Cycle RV battery is new and has a full charge. Ckd all the fuses and all are ok. No circuit breakers tripped. I worked my way down the line from the battery and tested the positive feed wire and got power but when I check the positive wire where it connects to the converter I get nothing. Bad ground? Or some other idea? An older motor home I owned had an actual 12 volt switch that had to be thrown in order to operate the 12 volt lights and 12 volt accessories in it but I don't see a switch in this travel trailer so I am assuming its supposed to be automatic. Thanks!

      Hi Michelle,

      yes, you do seem to have a battery or converter problem. If your battery or batteries are low on water this can easily be fixed by topping up the fluid level in them. If an ordinary battery charger is used and the problem clears up then a new converter is needed.

      If you have a wall mounted AC thermostat and the fridge isn't working properly, this another sign of a bad converter. first check the fluid level in the batteries before trying out a battery charger.

      Feel free to ask for more info if this advice doesn't help you with your problem. :)

      Hello! I have been having some problems with my camper and have read all the comments. A few weekends ago my camper lights stared going very very dim and my air (thermostat would not kick it back on). As well the refrigerator check light was on. All of the outlets continued working the whole time. We woke up he next morning and everything worked just fine. We are seasonal campers at a campground, and when we left I unplugged from shore power just in case. I did quite a bi of research and learned about the convertor and all the things that run on battery. The next weekend I plugged he camper in and everything worked just fine all 3 days here. When we left I kept the camper plugged into shore power. We went out tonight to camp and nothing worked at all except for all the outlets, inside and out, and microwave. I am pretty sure this is a battery or convertor issue, Correct? I am very novice and not sure where to start next. If I try to charge the battery or doesn’t work does that mean the convertor is bad?? Remember I m novice and a girl. LOL!! Can you talk me thru checking if it is battery, convertor or another problem?? Thanks in advance…

      In what capacity, Dana? In some older campers, house type breakers are indeed used in the correct 110 volt breaker box. Usually a 30 or 50 amp breaker box was used for the 110 volt AC service, but today's RVs utilize special breakers in breaker boxes designed for them.

      Randy Godwin 2 years ago from Southern Georgia

      Bob-- unless you are using a heavy duty cord this may be your problem. An AC pulls a lot of amps and along with the converter and other electrical items on the RV, it may have shorted out the cord.

      Try leaving the AC off and using another cord to see if any of the other 110 volt items will operate. If so, the cord is not heavy enough to run everything at once and you need one with heavier wire to handle the load.

      Well it seems that even after being plugged into it's very own shore power over night and all day, the fridge has not changed. It seems to be holding around 50 degrees though (safe is 34-40). The freezer is at a "soft freeze". It's not as bad as it was 2 weeks ago when we were camping for 3 days (fridge temp rose to 60 degrees then) but it's worse than if it's parked at home on 110volts in the sun with no air conditioning running. And we are as level as possible then as we are now.

      Maybe she doesn't like camping!

      Have you tried running the fridge from another outlet outside in the camp shore power panel? Using an extension cord, of course. This does seem strange if the fridge worked okay at home.

      @Txchiktraveler--The fridge uses the 12 volt DC power to operate the thermostat. Are all of your lights working correctly? Do you have two AC units on your RV? Just trying to narrow the problem down a bit so any more info you can give me might help.

      Hey Randy, we have a "new to us" 1987 Pace Arrow class A motorhome. When we have it connected at home with 110-15 amp our refrigerator works fine (freezer freezes/bottom registers 40degrees on thermometer). But the 2 times we have taken it to a campground for 3 days and hook up to their 30 amp it DOES NOT work. The freezer starts defrosting and bottom temp starts climbing up. We have checked and rechecked to made sure the MH is level. The only thing different from home and campsite is the amps, the AC is running and there are a few grocery items in it. We are baffled as to what is going on. Any ideas?

      Hello Jimmy, when you say nothing works, you mean you don't have 12 volt or 120 volt power? No lights, or no power from the outlets either? Check all of the ground wires in the power panels--both !2 volt DC and 120 volt AC--as well as the ground wires from the batteries to the steel frame of the RV.

      Are you connected to a shore line or trying to power it from the generator? I'm trying to eliminate the most common problems to begin with. More info from you may help me figure this one out.

      There may be a bad relay causing the problem Shari, unfortunately I'm not privy to the electrical system on many RVs as there are so many makes and types. Also RV generators are controlled by different types of switching controls on different campers also. Two blown 30 amp fuses seems to indicate a bad overload. How did the short occur exactly? Shorting the battery should have blown the 12 volt breakers, or fuses, at the very worst.

      when he arc'ed the battery (when he put it on to leave ) he said he heard something pop/click also the camper was plugged in when he did it with the radio on at that time the radio also stopped working , and after inspecting all the breakers and fuses we could find the only thing popped were the two push in type 30 amp fuses we replaced and even when it killed the 2 generators those did not pop again . in reading through the joke of a book they gave us with the camper the only thing that described what it was doing was in the power center section and named some kind of thermal relay ?

      Hello John Deere 1953, great moniker by the way. It's entirely possible the campground you referenced may have problems with low voltage campsite wide, but do you notice other RVs experiencing the same surges in time with yours? It should be easy to notice at night if this is the case.

      If not, then the problem my be your power converter cutting on and off trying to keep the batteries fully charged. If your batteries aren't sealed, then check to be sure the fluid levels are topped up as low fluid levels can cause the converter to kick on and off in a similar manner. Hope this info helps you out.

      Found problem,thanks. Grnd on extension chord was not making up at receptacle, took a little ohming with a meter to find it. Three wire hook up on 30 amp service,120 circuit, neutral circuit, equipment ground circuit. When you bond the rv panel neutral with the equipment grnd at RV frame you create a ground loop back to house source where neutral and grounds of house panel are bonded together. If you're with me, I would think neutral through RV would be isolated all the way back to house source along with RV equipment grnd isolated back to house source, not bonded together at RV frame. Since they are bonded at RV frame that puts " unbalance" load on frame. When you lose grnd connection the frame then becomes energized creating a shock hazard between the RV and earth grnd.

      Hi Tommy, it's possible the 3 fuses reading 7.8 volts may be coming off a resistor therefore reducing the voltage for some reason. I don't know what the fuse indicated by the w/n is representing. possibly something to do with the waste system.

      If the converter is operating properly, it should read 13-15 volts at the battery when the RV is plugged into the shore power. Hope this helps you find the problem, but I suspect the battery is the culprit.

      Hello Tommy, thanks for reading and for your question. Since the radio doesn't work as well as when plugged into the tow vehicle, I suspect a bad ground wire(s) where the on-board battery ground wires connect to the steel frame or at the power converter.

      These connections should be cleaned every season or so as they are notorious for causing 12 volt electrical problems when corroded.You might also test the camper on-board battery(s) to be sure they're holding a good charge. and to see how many volts the converter is putting out to the battery(s). Hope this info helps!

      Hi Milly, I suspect you may have a bad battery or batteries, or it could be a bad ground causing the problem as in Stan's case above. Running multiple lights may keep the converter going as it furnishes the refrigerator's thermostat with power. Check the battery voltage while the camper is unplugged to see if the batteries are holding a charge.

    • Randy Godwin profile image
      Author

      Randy Godwin 3 years ago from Southern Georgia

      Hello Stan, have you checked the batteries to see if they will hold a charge from the converter? This sounds as if the battery(s) are bad or that they are not grounded properly to the frame near the battery box.

      The converter is apparently operating correctly if everything works while plugged into shore power, so check the batteries while the camper is not connected to shore power to see if they are holding a charge. Also, clean the battery ground cables where they contact the steel frame of the camper. A bad ground will cause this type problem.

      Ask for more info if needed. :)

      Hi Mandy, and thanks for stopping by. Yes, it seems your thermostat is malfunctioning the way you described it. You should have no problem replacing it if you check to see how many wires your unit requires to operate the system. Many RV AC/heating units use the same thermostat as used in a home system. Check with Home Depot or Lowe's first before going to an RV repair center. You'll save a few bucks doing so. Thanks for the question!

      Phyliss--There are usually 2 separate fuse or breaker panels. One each for both 12 volt DC and 120 volt AC systems. The 120 volt system operates everything using a standard outlet plug.

      The 12volt system operates lights, vent fans, refrigerator and AC/Heat thermostats. The fuses in the 12 volt system are the same as used in auto fuse systems, either the glass type or colored plastic type. There are also 12 volt breakers in some RVs.

      The 120 volt system uses either breakers or house type fuses in the panel. I'm trying to determine which electrical system is at fault or whether the AC itself is causing the problem. Does the AC have a heat strip to proved the heating for your camper?

      Hello Tim, and thanks for the question. I really don't have access to the trailer's specs, but it should be relatively easy to access the power panels to ascertain the 12 volt source, whether converter or inverter. My guess is it would be a power converter as it is commonly used by various makers of travel trailers.

      It does sound like a power converter problem which may be checked at the on-board battery(s) when the system is being used. You should get at least 13-15 volts at the battery if the converter is working properly.

      Please ask for more info if you need it.

      We just purchased 2007 fleetwood hybrid trailer . We used a generator honda ex650 to power it up last night for about 3 hrs and then the power convertor / fuse panel started to smoke. I had it plugged in to a house receptical for a couple of days with no issues. Is it possible generator is putting out to much power ?

      The outlet has to be on a breaker by itself or either getting power from another outlet, Bill. If all of the 110 volt breakers are working correctly then I suspect a bad connection from another outlet on the same circuit. I'd check all of the outlets for a bad connection anyway. You can use the OHM feature on the multimeter to find where the wire is going to if all else fails.

      Hi Randy,

      There are no other outlets near the outlet under the table. Closest outlets are in the front over the driver and passenger seats behind cabinets for the TV and electronics - two outlets and the on the other side of the RV in the kitchen above the sink. The outlet not working is mounted in the storage area under the seat . So I can access the rear of the outlet that goes to a junction box - checked connections there and measured here for voltage - none. The cable goes under the seat which is on a slide out and then disappears into the top of an outside storage compartment - no access- see a cable coming out of the top and then goes into the under chassis toward the center and goes behind a large plate- no access.

      Have not checked connections in a junction box near the generator yet. Should I look at the wires behind outlets that work? Wish I had a wiring diagram. The outlet was being used to power an electric heater which has worked fine many times and never tripped a breaker.

      Thanks Bill

      Hello Bill. have you checked the adjacent outlets for bad connections on the wire going to the bad outlet. Since the other outlets seem to work okay, the bad outlet is on the end of the circuit or is on a circuit by itself. The latter probably isn't the case. Hope this helps you out.

      Feel free to ask for more info if needed, Bill. :)

      Hi Meagan. Are you sure the power converter is operating properly? Can you check the voltage to the onboard battery(s) while the RV is plugged into an outlet and let me know what you find?

      The fridge probably uses the 12 volt electrical system to operate the thermostat so the converter would affect this also. Get back to me when you can regarding the power convert output.

      Hi Randy,

      I have a class C Gulfstream Conquest model 6296D.

      The AC outlet under the dinette table no longer works. All other outlets work. The circuit breakers and fuses in the panel under the frig are all good. The electrical junction box near the outlet does not have AC. I tried the generator still no power to the outlet. I tried to trace the cable but couldn't see where it went. Did not see any cable damage under the RV. Tighten all connections in the circuit panel. At a loss at this point- also order one of your manuals - in transit. Any advise would be appreciated.

      Hello, I have a 1996 Coachmen 5th Wheel. I have a can use the fridge while plugged into an outlet. If the fridge is only running on battery and propane it will not work. The water heater, lights and stove will work on propane only but the fridge will not. Now the fridge will work on propane as long as the camper is plugged into an outlet but the second you unplug the electric the light goes out to the fridge only. It will not light using a lighter or anything. Battery is new and propane is full.

      Hello Ruth,

      Do you have an on board power converter to keep the batteries charged?

      You shouldn't have to use the generator to charge the batteries at all if the power converter is working properly. What exactly is a Nook reader? Certainly not a tablet or Kindle because they only pull a miniscule amount of power. More info may help.

      Just bought a 2013 Aspen Trail Travel Trailer. The initial charge on the batteries last several days. However, if I charge my Nook reader, the batteries go dead within a few hours. In addition, the radio will come on all by itself. We recharge to full charge with a generator but then the charge will only last one day. The dealer is saying the nook pulls too much power.

      Hi Ryan. have you checked the electrical heating element? These often malfunction and must be replaced occasionally. You may be able to check the element with an ohm meter to see if it is bad or not. No continuity is bad and suggests the element must be replaced. Not a complicated job at all.

      Brian--I suspect the power converter is not putting out enough voltage to keep the battery charged while everything is running. It could also be a dead cell in the battery causing it to not hold a sufficient charge to operate all of the 12 volt DC items on the system. Check out my article about RV power converters below:

      Feel free to ask for more info if you need it. Thanks for the question and your time, Brian.

      Hello Anthony. You should be able to look at the old converter to see how many amps your RV requires to run the 12 volt system. I would think a 45 amp converter would work for most systems but a 60 amp would even be better. Still, check out the old converter to be sure. Hope this helps and you can find some very good converters on this page.

      Feel free to ask if you have any more questions, Anthony. Thanks for the question.

      Hi Jason, it may be the lack of battery which is causing you problems with the fridge. An absorption fridge uses the 12 volt system to operate the thermostat on the fridge and the lack of a battery to furnish enough amps could be causing the fuse to blow. Otherwise I would check the converter to see if it is furnishing at least 13 volts. Hope this helps.

      My fridge keeps blowing a 5 amp fuse on the circuit board. The message board on the fridge displays "A" whichs means no power available. I do not have a battery hooked up currently and just using 110 volt shore power at home. Is my power converter malfunctioning? Fridge is an absorb type.

      Hello Greg, I suspect your 12 volt power converter to be the problem. While plugged into the 110 volt power supply, check the 12 volt breaker panel to see if you are getting at least 13 volts DC power to the breakers. If not, then look to have your converter repaired or replaced. The article I have linked to below may help you find the problem easier. Thanks for the question and good luck with your repairs. Feel free to ask for further help if needed. :)

      Hi Joe,

      I'd start with the batteries to see if they are fully charged. Make sure the ground to the frame is making good contact or nothing will work properly. If the batteries check out fine, then on to the 12 volt breaker panel and check to see if power is getting to the breakers. Let me know what you find from there.

      I have a 2013 Camper that I just purchased and used this fall. I recently parked the unit and went to start the generator and all is dead. I plugged the camper into my truck (tow package) for a couple of hours given that it was the most convenient way to charge my batteries (I thought) and after two hours no charge was taken - everything is still dead. In addition - the lights will not even work off my tow hitch pacakge (external marker lights work just not the camper lights). Where do I go next... All breakers and fuses look good.

      Not sure about other GFI's in the circuit, Gary. These things are notorious for going bad and causing shorts in the line circuit. If you have power to the breaker and from the breaker then the problem could be in an outlet. More info may help.

      Hello Robbie. Yes, the generator is probably affecting how the system operates but should be not be a real problem.

      I have a camper hooked up to a generator with a two-way fridge. When I'm running the fridge in auto-mode the "check" light comes on, but all I have to do is flip on any light and the "check" light goes off. Also, when I unhook the battery (while leaving the generator on) the overhead lights act abnormal. Lights that are normally controlled by a switch won't come on until I randomly go around the camper flipping other lights off and on. Do you think all of this is because I'm using the generator?

      Hello Jessica, sorry to take so long to respond but I've been without an internet connection the last 4 days. If you have a propane furnace it should work since the thermostat runs on 12 volts. If you have an electric furnace it will not work only on the battery.

      Randy,

      After not getting an electric site we decided to buy a battery just to have heat, after looking for 3 hours for the "switch/fuse" that would switch us from AC to DC we gave up, we have a 2002 Starcraft Orion. Any ideas what we need to do to get it to work? When my husband did something (not sure what) the running lights on the camper would work, but we couldn't get the interior lights or heat to work

      Hello gonkapa! The interior lights should work with only the battery connected even with the external power disconnected. Are you sure the new battery is fully charged? There could be a switch but I don't think so in this case.

      New to Tent Camping... Need Help! I just purchased a 2011 Palomino 4124. The battery was dead so I bought a new deep cycle battery. I connected it and tried to turn on the interior lights to see if it worked, but no lights come on. I'm not connected to an external AC power source or generator. Is there a switch or something to operate power off the battery? Please help, thanks!

      Hi Dave. Did this trouble begin after returning from a camping trip or after setting up on the site? It's not unusual for the wiring going to a slide-out to come unplugged or detached in some manner when the slide-out is operated.

      The wiring has to be flexible in order to move along with the slide-out. Finding how to access the wiring is the next problem. Obviously, if you are getting 12 volts on both sides of the fuses the short is between there and the slide-out.

      Hi Randy,

      I have a 2006 Salem Trailer, vin #4X4tsmp266j015816 and have lost power to the lights to the living area pull out and the outside lights (porch light and security light). I have 12 volts on both sides of the fuses, but on one fuse the red LED lights when checking output voltage. Where should I start in my troubleshooting?

      No problem, Sandy. The H/W thermostat operates on the 12 volt battery system when the camper is not plugged in to the 110 volt system and it was still active.

      Ok thanks...I wasn't sure because I only noticed it was left on when I walked by the camper after we had parked it at home and heard a faint high-pitched humming sound. After I turned off the switch in the command control box the red light went out and the noise went away.

      Thanks again for getting back to me so fast!

      We left the switch on (in our monitor box) to the electric water heater in our Jayco 26RLS camper. The camper was not plugged in at the time. Will this do any damage to the water heater?
