Land line tripping outlet breaker

[dr ron]

I have my Class A Reflection plugged into and outdoor 110 V outlet (with adapters), It has been charging OK. I had a plumbing leak down behind the shower and now when I plug into the outdoor wall outlet the GFCI breaker trips.The shower ids on the oposite side of the RV from the batteries. Don't know why this is happening.The converter is new.

Probably when the shower leaked it leaked onto some wiring below & it is still damp. GFCI are very sensitive....

Thanks for the reply. Actually I had to replace the bathroom sink faucets, the toilet valve, the shower faucets and the kitchen sink faucet springs etc.
So far the toilet and the bathroom sink are holding but I'm afraid to turn the water pump(new 55psi) back on. It could be water on some connections below.I'm taking it into Camping world for a comb over on July 5th. Maybe they can tell.

I just unplugged the converter/charger from the outlet feed from Auto transfer Switch that it was plugged into , and plugged it in directly to the outdoor outlet and it works. Therefore I would deduce the fault being in the Auto Transfer switch would you not?
