Front Alternator Inoperative

[Jack Moore]

I agree with take cowl off and check fins I had this only happen once but maybe it will do it again somewhere else . The woodruff key on the alternator shaft had broken and would spin on the shaft when it was a cold start or run it would catch and work but as the shaft would heat up it would no longer heat up and you will get the alt out lite come on saying not charging....Jack
