1999 f 150


I replaced the alternator a few months ago, and everything was fine for a few months. Now the battery is not charging, the same issue as before, did I get a bad alternator is something “blowing” the alternator?


Are you sure it’s not the battery?


I havent had is tested but its a good quality battery, 3 years old and it holds a charge well


Stop by an auto parts store and let them do a curbside battery and alternator check, free.


Also check the wiring to the alternator.


“Rebuilt” alternators (and everything else) DO have a high failure rate…
