I used my meter on my altinator and grounded to the battery also I drove it around the block and didn’t gain any charge and at idle according to the gauge cluster display and my craftsman companion app I lost voltage from the battery it went from 11.3 down to 10.8v

If you are checking voltage at the alternator and seeing low voltage sounds like a bad alternator….when checking alternator voltage it’s better to use the alternator case as your ground and not battery ground…the case has the lowest ground “potential” when the car is running.

also I’m not sure though still what caused it to burn up the first time I took out the battery and cleaned grounds today they didn’t seem very dirty though also I’ve looked the belt over and nothing seems amiss there

do you have any idea what would have caused both altinators to over charged the first one literally burned I opened the hood and a puff of white smoke came out and it was severely blackened this second one I can smell it burning and the coils are blackened a little bit
