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!

        Jesse, inspect the negative battery cable where it attaches to the steel frame. A corroded or loose ground here will cause all sorts of strange problems.

        Also, see if there's an inline breaker on the positive battery cable leading to the converter. Some 12 volt DC systems have them and some do not.

        Jesse, try turning the converter breaker off in the 110 volt ac power panel as it isn't needed and is probably making an alarm sound because the converter is not getting power to convert.

        Joe, does the roof work while connected to the shore power? If not, then it may be a problem with the switch.

        Check the switch connections for a bad ground.

        I have a 2004 rvision - recently purchased in great shape. I parked it after the first trip and the heat was left on the on position (thermostat) - I did not not notice for about 2 months - it ran through the propane- I turned it off - all was good- 1 month later when I checked on it the fan was running- no obvious reasons- fan is on auto- thermostat is on off position. The only way it shut off was when I turned the power off at the solar (upgraded to keep shore power when dry camping by previous owner). Am I missing something obvious or is this a bad fan relay or therm?

        Thanks- anything helps. Btw my first trip out I had full hook up and no hookups on different days- the heater kicked on and off in both circumstances just fine.

        Bryan, the overhead light is on the 12 volt system. I don't know if you have a converter or if you're using the pickup battery. I suspect you do have a failed power converter of some sort somewhere. You'll just have to find it and check it for power.

        Debra, check the main in the 110 volt power panel first to see if there's any power getting to the circuits from shore power. If not, check the power from the shore connection.

        When you say "all other electrical is working," are you referring to the 12 volt fixtures such as lights and vent fans? A bit more info may assist

        me in helping you find the problem.

        Randy, still same issue. Seems like nothing, (battery charger connected-charging @15 amps, or running generator, etc) makes any difference. Connected to 110 at home presently and all other components seem to work, (tv, microwave, all 110 outlets). It seems like when either furnace tries to start or is running is only time I have this problem. Frustrating...

        Danny, this sounds like a power converter problem. Try connecting a good battery charger--not a trickle type--and if everything works properly then the converter is bad or weak.

        I am currently experiencing a problem with power to my furnace in my class A motorhome. When running and turning on a light, water pump, etc. the fan speed drops dramatically and lights flicker or dim sometimes turning off. If both furnaces are started both shutdown. I found one of the house batteries completely dry and refilled with distilled water and charged it to full power, but problem still exist. Any ideas/suggestions?

        Hi,

        I have a 2005 Lance cabover camper with Atwood electric jacks. I recently replaced the deep cell batteries, and found about a week later my right rear jack will not stop after activating the jacks. I've removed the battery from my jack remote thinking the button was stuck. I've tried another jack motor, checked the connections to the jack motor, and can't seem to figure out why this one jack is getting still constant power? I did figure out that if I reverse the two plug pin, I can reverse the jack direction, so at least I can unload and load my camper in a pinch for service. Not sure if the new batteries are related to the problem. Any ideas would be much appreciated! Thank you in advance!

        Melissa, I don't have any info on the type /model of your water heater. If the 12 volt thermostat is working properly then the igniter is probably the problem.

        I suggest you find a schematic by contacting the maker of the H/W heater online.

        John, I own a 2013 Keystone Hornet. Last week my water heater stopped working with electric. I works on propane, and we replace the thermostat, but then on Monday, my heater stopped working. It stars up, but It isn't getting the electric spark needed to start. All the fuses are fine and we can't find anything else wrong. Where can I find diagrams or schematics on the electrical system so we can check over everything to see what is truly wrong? I am at my wits end. Any help would be greatly appreciated.

        BJ, have you checked the main breaker in the power panel yet? Turn off all of the breakers except for the main and see if you have power. If so, turn on the other breakers one at a time until you find the circuit causing the problem.

        If this doesn't help get back to me and we'll try again.

        Hey Randy, I have a 2013 Dutchman Komfort 5th wheel, Thursday night we apparently had a surge go from shore power into the rv. It blew a 40 amp fuse in the converter. I can run 12 volt and get partial electric and run propane for stove and fridge. I can run the generator and have full power. Replaced the shore to rv 50 amp power line and do not get shore power into the rv. What am I missing? Is it the parallax power distribution unit? Or is there a mystery breaker someplace I need to reset?

        Okay, I got you John. Check the battery negative cable end where it attaches to the steel frame of the RV first. A bad ground here will cause all sorts of problems with the 12 volt system.

        Check the converter breaker as it should be getting power from the generator the same as from shore power.

        Have you tried connecting a good battery charger up while on generator power? You may have to use one if there's some sort of short in the converter breaker circuit.

        The plug on my RV has a male end plugged into a female end to complete the circuit on the RV if you are running the generator. when you are getting power from other outside source--30 amp,you unplug it From "_ Itself " To plug in the 30 amp. My problem is Everything works if you are running the generator or plugged into 30 amp. But the lights will not work just off the 12 volt system .

        Joe, check the voltage at the battery and if the converter is working properly you should get a reading of 13+ volts.

        As far as the outlets are concerned, they are separate from the 12 volt system other than there being a 110 volt breaker for the converter.

        You'll have to test each breaker in the power panel to determine which are not working properly. Also, check the ground wires as they may be loose from the camper movement during travel.

        Hi Randy, have a Fleetwood Wilderness Yukon, 03 I think, where one set of outlets work but another won’t. As far as I can tell they both run off the same fuse which is not blown and the breaker isn’t flipped. The non-working outlet was running an small electric heater which I’m sure is the cause of my issue but why would some outlets work and not others if all the circuits run through the same fuse box?

        Hey Mark, check the battery ground cable where it attaches to the frame for corrosion. This probably isn't the issue in your case but a bad ground here can cause all sorts of weird problems.

        Also, if a charger is doing the job then there must be something shorting out in the converter connections. I'd be interested in what you find when you check with the meter.

        I have a Keystone camper that I use as a cabin. It is hooked up 100% of the time to a 110V service. I recently found the circuit breaker tripped for the 12V converter (all other 110V circuits were operating). Upon resetting, it immediately tripped again. Checked all of the fuses, which were all good. Replaced the converter and breaker, but still tripping immediately. I normally do not have a battery connected at all, but connected a charger to see if the 12V would work from a 12V source. It did. Planning to go back down with a multimeter but wanted to check and see if you had any thoughts... Thanks!

        Hi Shawn, sorry for the long delay in replying to your question. First try connecting a good battery charger to see if the power converter is working. Also check the battery to see if it is good. You can check the voltage with the converter breaker off or the camper unplugged.

        And check the negative battery cable connection to the steel frame of the camper. It's common for this connection to corrode or be loose.

        Dave, probably a bad ground in the recept you're hooked to unless you have 50 amp service. If so, the bad ground may be in the on-board 110 volt AC breaker panel.

        Gordon, try connecting a good battery charger to the batteries and if the lights work properly the power converter may be bad.

        John, I assume you've already checked the line at the RV park so I'll avoid asking that. Try using a good voltmeter when the power goes off to check the main breaker. It could be loose or even bad. Let me know what you find and we'll go from there.

        Della, try connecting a good 12 volt charger to the battery, and if the lights and fridge work then the power converter is more than likely bad.

        Hi Randy

        We are staying long term in a RV Park we have a 2018 trailer 50 amp. Our power keeps going on and off at different times sometimes only for seconds or can be 10 minutes . It’s been working fine for 5 months. We will sometimes have a 8 hour period of nothing . All through the summer nothing at all . We have not added anymore power sources . What can possibly be the problem??

        Gordy, first check the negative battery cable where it attaches to the steel frame of the RV. This is the main ground for the entire 12 volt DC system. It is not uncommon for the is connection to corrode and cause a bad ground.

        If the ground is clean then connect a good battery charger to the batteries. If everything works okay then the power converter is bad.

        Just got this 94 Newmar kountry aire class a rv. When I start the engine is kills my auxiliary batteries and when I plug in the shore line just my outlets are working and that doesn't charge my auxiliary batteries either. Change the house fuse but still won't go from DC to AC

        Randy, the fridge thermostat operates on the 12 volt DC system. Is everything else 12 volt operating normally?

        Justin, you might try cleaning the negative battery cable where it attaches to the steel frame of the camper as a bad ground may cause the problem. If the charger works the ground is good.

        Justin, both the AC and the fridge use the 12 volt system to power the thermostats.

        Thanks and I will give that a try. If it is the converter why won't the AC and fridge come on? They have separate breakers with good voltage to them.

        Justin, this sounds like a bad power converter as all the items you mentioned not working are on the 12 volt system in some manner. You should have a battery or a place where the battery should be. Find the area and connect a good battery charger to the posts or cables to see if everything works fine then. If so, a new converter will solve the problem. Feel free to ask for more info if needed.

        Hi Randy

        I have pull behind that has been working fine on shore power out at deer lease. Had big storms come thru after hurricane in TX. I've some electrical know how. Power pole and supply are good. 120 into camper. 110 - AC, WH, microwave, GFCI, fridge breakers. All receiving 110. Checked and reset all breakers, checked all fuses. Problem is AC, Fridge and anything 12 volts not working. 110 wall plugs out outside work. Microwave works. Never seen a battery on the camper. Inverter is getting 110. Any ideas where to look? Only thing I noticed is, when I leave blower and lights on and kick shore power on it all runs a split second and that's it. Thanks and keep up the great work helping us.

        Bob, probably the converter or a warning monitor of some sort. I don't have an electrical wiring diagram for your camper.

        No problem Lavenda, I just wish I could've been more help to you. Feel free to ask me if you have another RV problem. Most of the time I can help, but nothing is better than to actually see the problem live. :)

        I found a WF-8935 converter with amazon. This is the number on the old converter is it the one I should order. I cannot find away to ask questions with amazon, but it is the same converter that was in there. I really don't have no help sorry for bugging you so much.

        yes I have checked converters on Amazon and they are to big to to put on the panel with the fan. Or I don't need that no more. I am going to check again, Will a WF-8955 converter fit in a 8935 spot under my fuse box?

        Lavenda, most converter s will work as long as the amperage is the same or better.

        Lavinda, I need a bit more info such as are you sure the breaker in your Mom's home isn't tripped? And is the 110 volt power panel in the camper powered? Do you not know anyone who can tell me more about the problem as I need more info in order to help you.

        I need a WF-8935/45/55 amp coverter . How do it find this for my camper. Do I go by the 55 amp coverter for a 8935?

        Lavenda 7 months ago

        I had my camper trailer checked out today and the coverter box needs to be replaced these are the no. I got off it WF-8935/45/55amp and also from 35/45/55Amp main board Dc output. What do I need to search for to get this item?

        Hello Randy I finally got my 110 30 amp power cord plugged into a 110 30 amp socket in my mother's trailer I have no one to help me, but I still didn't get any electric to my camper. Help?

        Cole, it's possible the vacuum and IPad were plugged into the same circuit the converter was on and was damaged when the converter went out.

        The battery's are new and taking a charge. The micro wave inside light will come on so there is power going to it but that is all it will do. I have ordered a new PD 9245 to replace the 9145 that smoked. Could the vacuum and the I-pad be affected on 110 by a bad converter?

        Randy Godwin 7 months ago from Southern Georgia

        Cole, check the battery to see if the converter is charging it properly. If so, you should get a reading of at least 13 volts DC. Unless the microwave has a 12 volt thermostat it shouldn't have been affected. Have you checked the microwave outlet yet or the breaker the microwave is on? Smoke is not good and I suspect the converter may be toast.
