Took in the alternator to get it checked and they said it was good. Put it back on and it seemed like it was charging according to my volt meter (14.24-13.5 v)

Today, it's not charging. Only reads 12.2 v while running. Is there a fuse or something I need to check? Grounds? It seems intermittent.

2003 F-250 V10 6.8 liter 255,000 miles.

Thanks in advance!

 

The battery light is still on

 

i'd be replacing the alternator. i've seen some work intermittent before going out totally.

 

Thanks, AlaskanEx!

 

Changed the alternator and its all good now. Thanks!
