When I have the Shore power connected: Batteries are at 13V
With Generator: 13V
With Alternator: 12V and steadily drops to 11.5 no matter what the engine RPM. All DC house systems are turned off, especially the refrigerator
I checked the breakers on the Port Side aft wall (where the orange wires come in from the alternators and they are good. Checked the output from the Alternators with the engines running and it is 14.2V.
Really confused with this. Is this normal?
All batteries replaced last week.
