Alternator issues


My port alternator showed 11 volts on the gauge yesterday on a sixty mile trip. It showed 12 on the gauge with the generator running today on a 40 mile trip. I put a multimeter on it this evening and it is producing 13.7 volts. The starboard is producing 14.7. The battery charger was pumping amps last night indicating that it had some real charging to do.

Time to replace? Anything else I should check? The belt is fine and the alternator is spinning normally, just producing less voltage than the other.

Any thoughts would be appreciated!
