alt going crazy
I think we are all guilty of this a number of times. *Low voltage battery circuits hide dirty connectors and switches very well.*
I had a simular problem with my port side alternator, except it wouldn't charge at all. Took the alternator off and had it tested, checked out fine. I finally swapped the alternators port and starboard and it worked fine on starboard engine. *Cleaned battery terminals and checked the whole circuit out with a volt meter all the way to the alternator. *Everything looked good but the alternator still wouldn't throw a charge.
Connecter and post at the starter looked good, but I cleaned it anyway and now the alternator works. *Moral of the story; just because you can see 12 volts on a volt meter, doesn't mean the connection is capable of passing enough current to excite the alternator.
