Hi folks. I have a ProMariner ProSport 6 for occasional dockside topup, plugged into a GFCI outlet onboard. Lately it pops the GFCI every time as soon as shore power
is connected. Is it likely the charger
is hooped? Is there any simple way to test it? It's still under warranty, but I'll probably have to mail it somewhere, and I want to be sure it's the problem before I do that.
I've tested the shorepower outlet, the cable, and the onboard outlet every way I can think of. (The gfci is simply wired directly to the shorepower receptacle; i.e. there's no real AC circuit on board, I just use the shorepower cable (carefully!) as an extension cord.) The only other 3-prong appliance I have aboard is a laptop charger
, which works fine in the same outlet, though of course it doesn't draw much. I've tried a receptacle tester with a GFCI test button, and everything checks out.
Thanks for any advice!
