5th Wheel Power Problems New Converter

My parents needed somebody to take care of their camper while the get settled into my Dad's new duty station. So they asked me to stay in it a while and just make sure it doesn't fall into disrepair.

About 3 weeks ago I went on vacation out of town. When I got back, there was no AC power to the camper. It didn't look like any breakers were kicked, so I flipped them all off and back on. As soon as I did that I heard some pops behind the breaker and smoke started coming out of the wall. So I flipped all the breakers back off and opened the storage compartment that gives access to that area. The smoke was coming from the converter. The next day I was able to find a place that had one. Got it installed, and everything worked fine.

2 weeks later (this morning) I go to microwave some leftovers for breakfast, and I think I heard the heater start to kick on. Everything powers down again. I don't want to make the same mistakes as last time in case I can still salvage the converter that only one local dealer carries and charges $330 for (nearly double what I could get it online for if I could wait on shipping).

My dad advised I test the circuit breaker voltage readings. I got 250v on the big breaker, and the others don't seem to be showing anything.

Any help or advice will be greatly appreciated as I'm a novice on RV electrical and my dad is currently stationed too far away to sing by and lend a hand.

  • A spider had started nesting in the 50 amp plug, and the ground was all full of junk. Cleaned it out, all good. Thanks a bunch!

    This is a typical wiring setup for RV50A and RV30A service...
    also a couple of AC VOLTAGE measurement diagrams to test the 50A and 30A circuit using a multimeter...

  • Where are you plugged into for AC power?

    It has lost the neutral.......either loose terminal or burnt wire

    Possibly bad power cord.

    But neutral is not connected
