is right on the alternator. It was replaced by the alternator shop -- apparently un-necessarily.
Last year, after 13 years, I had the alternator rebuilt. Our Westerbeke
7.6 KW generator had about 1400 plus hours on it.
When I noticed that I couldn't start the generator, we determined that it was beause the generator battery had been drawn down. By parallelling the engine start and geneartor batteries, I can start the generator (and recharge the generator start battery).
However, the Westerbeke
uses an electric fuel pump
which constantly draws power while the generator is running. So, eventually, without and alternator, the generator battery will draw down.
(I have a Mastervolt Inverter/Charger with trickle, or "echo", charge tap for the generator; however, the little automotive fuse for that "popped". We aren't quite sure if that is related or not; however, we can find no reason that it would be. The marine
electricians that installed can't either.)
