gfci still tripping
Well, I've completely removed both my PowerWatch reverse polarity indicators to
re-do them. Decided to check the coach with them removed and the GFCI still
trips when I plug the 30 amp cord in. It trips when I plug it into either of
the two 30 amp receptacles on the coach. (I do not own a 50 amp cord.) Trips
even though all the breakers are off including individual circuits, main breaker
and the separate 30 amp disconnect breakers. If I switch the master shore power
switch to off, gen or 50 amp it does not trip. It does trip if this switch is
set at 30 amps. If I start with everything at off, then gradually flip switches
it seems to barely hold, but if the switches are on and I plug in the cord, the
GFCI trips, suggesting I am right at the trip point.

One possible problem area is the genset which has been replaced in the past, but
does not ever seem to have been run prior to my getting the coach.

I am looking for advice on the proper troubleshooting technique for this
problem.

John,
There are some active circuits even when all breakers are off. They are involved in the circuit that warns you if you turn the ignition on with shore power applied. Turning off the breakers only breaks the "hot" side. If there is a cross between Neutral and ground it will still be there even with the breakers off. That is why I had to disconnect the neutrals in order to isolate my problem. There may be a different or better way,but this was the only way I could think of.

I had a hot/neutral on the 50 amp side screwed up a good 4 day trip fixing it. My fix wast completely remove that stupid thing. I know the put it there because somebody at some time drove away with the campground electrical in close tow. It just like a caution or warning in a set of instructions because someone did the thing that they warn you about regardless of how fullish it sounds.
