Well, here's what I have. 25' gasser. The volt meter started showing less than 12 volts while on the way back in on my last trip. At the dock, put a meter on the alternator. 14.2 volts coming out. Next put the leads on each battery. Both showed 13 volts at idle. Disconnected leads and load checked each battery. They're fine. Re-connected everything and put the meter on the voltmeter leads and it read 12.5 volts at idle at the dock.
I'm thinking a bad ground.
Thoughts?
