Hoping I can get a little direction from those that know a more about boat electrical systems than I do, plus my age isn,t helping me at this stage. I've got to give a little background first, hoping it'll make it easier for anyone to follow along. First of all let me describe the boat. It's a 31.9 Boston Whaler with twin 6.0 375 hp inboards. It has a galley and shore power connections. Last September my wife noticed that the front burner on the electric stove was hot, naturally I disagreed with her saying the breaker is off so it couldn't be. Well. she was right, although I still can't figure out how. anyway when she tried to move the stove there was a good sized spark from the control switch. I cut the shore power and removed the stove completely. Since that time whenever I hook up to shore power to charge the batteries or run the a/c the main pops instantly. I thought that maybe some damage had been done to the 30 amp main when the stove shorted like it did so I replaced it with the same type breaker. This did not fix the problem. I have since removed all connections from the A/C panel except for the battery charger, which I am going to remove next. With the shore power plugged in you can turn on the main and all is fine , the instant you energize any other breaker the main pops almost simultaneously. I must get this fixed before launch this spring , even if it means rewiring the entire A/C portion of the panel. So all of you guys out there that love hair pulling problems please give me a hand and see if we can get somewhere with this. I'll post again with more results after I disconnect the auto charger. Thank you ...Leo
