Attempting to bird dog this electrical issue. 1996 Overnighter with 2003 Yamaha 225, dual battery set up. I can start on battery one but the battery dies shortly after? thought I must have had some sort of slow drain so charged it overnight and then tried it again the next day. It ran for a few minutes I docked to get fuel, tried to restart and nothing, no gauges or anything on #1. I have to then go to #2 and start and it runs great, all day long, no issues, but switch to #1 and the engine dies in 20 seconds.
-Bad Battery? Maybe but they are new interstate group 24's
-Loose Wiring? Maybe, but what loose wire would let the engine run and start on #1 then deplete it? Seems it's not getting the charge from the alternator.
-Bad alternator? Maybe, but #2 battery runs all day long?
