2011 5.7 350 Mag (300hp) Mercruiser/Bravo III
Serial: 1A62xxxx
2011 260 Sundancer, 2 batteries, promariner 20 amp charger. Simple Question: How exactly is the charger connected to the batteries? I see the A/c wires coming in , I see 2 red and one black going out towards the cabin . i see the on/off switch breaker switch for the battery charger ,, what I don’t see are any wires connected to the batteries other than the main battery cables. It’s a thing of Beauty to see nothing stacked on the terminals. .. is this how cruisers with on-board chargers work?
 
Sounds like your charger is wired to the battery switch(s) or the common buss bars. Time to trace wires….
 
Aren't the later year boat's battery charger outputs wired to the DC main circuit breaker panel? Isn't there a circuit breaker for each battery bank?
My boat, a 2006 is.

Yea that must be it, it’s so easy it’s complicated and probably can charge faster on main cables??, thanks
