Your Monitor panel operates on 12-VDC from your COACH batteries, so this one is a little strange. You didn't say what model RV you have, so I will assume it is a motorhome and that you also have a water pump switch in your service center and near the sink, all wired so that any one of them will operate the water pump. SO, do your other switches operate the pump??? Some RV's will have two 12-VDC fuse panels in them; one near the dash and one in the rear somewhere, so check if you have this condition and a bad fuse in the second one.
But, logic says that you do not have 12-VDC to this Wall Monitor panel which you can check with a multimeter.
The 110V circuits in my RV are not working with either shore or generator power. I’ve reset the breakers and the GFCI. I unplugged it from shore, and with the generator running, I measured 110V across the line and neutral terminals labeled “Primary,” “Aux” and “Load” on the Transfer Relay Delay (TRD). Does 110V on Primary and Aux terminals at the same time indicate a faulty TRD? With 110V on the “Load,” but no power at the receptacles, where does my problem lie?
I bought a new Atwood LP detector to replace one which was in an old truck camper. The old one seemed to work fine, but I had heard they should be replaced every seven years. The new one was installed just like the old Atwood. The new one works fine until I plug in the shore power and then no power. Unplug the shore power and again it works fine (green light). Does this new detector just need to be wired to the 12 volt DC with a 1 amp fuse and bypass the converter?
My compressor for the AC buzzes like it’s trying to start and then shuts off after 5-10 secs. The AC thermostat is new, all capacitors are new. The compressor gets burning hot to the touch. The drain for the condensation is not clogged. All the coils and fins are clean. Could it be the compressor? Basically a whole new unit?
My new battery charges back up, but I don’t get any voltage measuring from the thermostat negative to trailer negative so no ground problems. I can jump the thermostat DC in to the cooling wire and I hear the relay click, same with the fan. The Cooling and or Fan do not turn on, but if I jump the 110v at the control box the fan and cooling turns on. What could be wrong?
I have one car & 2 trailers. A boat trailer & a utility trailer. When I plug the car into the boat trailer, everything works as it should. When I plug the same car into the utility trailer, the marker light come on & the left brake & signal light work, but not the right brake or signal light. The bulb is good. What else can it be?
