Ok, need some more help.
I have dual batteries onboard that were installed last year. I noticed yesterday that it seemed that the charge levels were a bit low. I show upper 13-14.1 volts when running so the alternator seems to be fine.
I usually run in the 1+2 switch position assuming this will ensure both batteries are charging. Is this a mistake? I switch off at the dock, but the boat stays in the water and has the bilge pump bypass the switch for obvious reasons. Boat gets used one pretty full day every week or two lately…. Sometimes two days on the weekend.
Is there anything I should check, or am doing something wrong?
That all said, I have a 25 watt solar panel(could get bigger), and wondered if I should set it up to charge the batteries while I’m away, but that likely needs some charger circuitry that I’m not sure how to connect. Anyone know if that’s a big enough panel, and a recommendation on a charger and wiring diagram?
Thanks!
