B&C 60Amp alternator failure modes
Subject:    B&C 60Amp alternator failure modes

During a stabilized cruise, I noticed my voltage drop to 12.8.  

The backup alternator did not come on line (no indicator light).  

After a few minutes, voltage was back up to 13.3.

I usually see 13.5 as it is behind an E-Buss diode.


Am I looking at a slowly dying alternator?  15 years old - about 450 hours.


Thoughts?


Thanks,

Ralph Capen
