"I've got a merc 165 L6. You all may remember my alternator troubles from last week. We decided the problem had to be my alternator since I was only getting 11.4 volts at the alternator with the engine running. So, I bought a new alternator from this site, and I'm having the same problem. I charged up the battery yesterday and I've got a full 12.5 volts at the battery. With the boat running I've got 12.5 volts at the alternator. Is there a regulator on the alternator that shuts it down when the battery is full? Or should it always be reading 14 volts?"
