After de-winterizing my 2004 Wanderer Wagon Toy Hauler, everything was operational. After disconnecting the RV power from the generator power jack and plugging it in to the house power, it tripped the GFCI on the house outlet. After some brief continuity checks, I found that there is continuity between the two blades on the 30 Amp plug. Any ideas what my next troubleshooting step should be? I could not find a wiring diagram online. I know the RV does NOT have a DCto AC inverter, but obviously has a converter. I do not know how it is wired however.
Thanks!

Stuart If your converter is in the circuit, a continuity check will show a connection as the coils of the converter transformer are low resistance.
Turn everything off at your main trailer breaker and try again. If your GFCI does not trip, turn the trailer circuits back on one at a time to isolate which one is causing the issue.
It is possible the live and neutral are reversed at the trailer, that would trip your GFI.

One way to start is to flip off your breakers one at a time and see which one disconnects the continuity. It narrows it down a little. Also, a converter usually has a fan that turns on and off with an internal thermostat. Check around and listen for it running.

I will start with these recommendations. I wish I was at home because I would jump on iyt right now! Alas, I am at work and have to wait. Haha
Thank you for your suggestions. I did not even think of the possibility that the continuity between the blades may be normal. And to be honest, I am using a cheap analog meter so I was just looking for open or short. BTW, I am a trained electrician, but I am used to working on things that fly.

Start with all breakers off and plug in.
Then turn on the main
Then turn on the other breakers to discover what circuit trips the GFI.
Suspects are moisture in the outdoor connector and possibly the converter is leaking too much to ground.
Your home GFI might also be a little over sensitive.
Post what you find.

There is also the possibility that there is a neutral/ground fault (short). If this is the problem, shutting off the breakers will not solve the problem. Here are some suggestions for chasing down & fixing an RV that trips a GFCI: Tripping GFCI.

One more quick question; I have never before plugged the RV into a GFCI outlet. This is the first time. Is it possible that there has been a ground fault issue with the RV from day one? I am the original owner.

Great advice from all! I will definitely post what I find when I get home and jump into it. Going to the sand dunes this weekend so I hope it is something simple.
Thanks,

I have a relay in my coach that will trip the GFI if the relay is connected! Took me a while to track it down but as soon as I took the relay out of the picture I was AOK. Used to prevent the Inverter from trying to power one of the roof AC units. I "think" it might be a bad relay.
