My 2007 Larson 274 Cabrio has a strange electrical gremlin that just blows my mind when troubleshooting, so perhaps someone could take a stab at the next logical step.
It will start right up with the Perko switch on both or #2, but just clicks like a dead battery on #1. Both batteries were new in 11/19.
I really don't want to lug two new batteries down the dock only to find it doesn't solve my problem.
I can't even seem to figure out which battery is the bad one. The volt meter is labeled port and starboard, but both are on the starboard side. The Perko switch is labeled 1 or 2. The breaker panel in the Perko switch box has battery charger 1 and 2. I only see one battery charger labeled 20 amp hidden behind the holding tank hoses and lots of wires, can't see where the wires from it lead. I not sure if both batteries are getting charged from shore power, but both charge with the engine running.
I drew a diagram.
