I am new to the forum (2002 260 DA) and am very interested in thoughts on comments about a battery drain issue I had this weekend.
I purchesed and had professionally installed two new glass mat batteries in Feb. I have run my boat no less than every two weeks over the winter and the volts looked strong all the way out to Caladisi Island Marina this past Saturday. We left the battery switch set to "both" and walked to the beach for about 2 hours with no equipment running, just he main panel was on. No other breakers were on.
When I returned the CO3 moniter was giving a low battery cherp and after investigation I realized that the volt gauge was at zero!
I connected to shore power and turned on the AC converter for 2 hours to get to 10 volts, then turned her over with the shore power still connected. She fired up slowly but made contact. I unhooked and reved the engine in idol till we read 12 volts then headed home. volts were back to 14 after a 4 mile run. and everything was fine when I re-started the engine to flush at home.
Any ideas as to what happened???
