Ideas?? On-Board Battery Charging System tripping circuit breaker
Just got back from Canada yesterday. On Friday, got caught in a driving rainstorm for the better part of 3 hours while fishing a river up there. Naturally, tried to dry her out, but ultimately had to put the canvas on over a wet boat and trailer it 12 hours in 90+ heat on Saturday. Took the canvas off Saturday night (the boat is garaged, always). Note that it charged the batteries just fine Friday evening before the canvas went on. On Sunday, opened all the compartments, tried to plug it in for a trickle charge and tripped the breaker--something shorting out. Checked the battery compartments--ignition battery looked a little wet, so pulled the boat out into the sun, let it dry out for a few hours and tried again. Tripped again. Can't see any water, and the charger and the compartment it's in look and feel dry. This is a 4 bank charger, 3 AGM trolling batteries in a 36 volt system with one "wet cell" ignition battery. This is the 5th season for the batteries and charger. Never had any problems before.
Any ideas on how to test what's happening and where? I'm going to let it dry out for a few more days, but I don't think it should be doing this.
