one battery or two? start by cleanining battery posts and terminals, maybe a bad ground does your ex have a gage or just a light if the gage shows charging probably a battery problem assuming connectons are tight and clean. remember easy stuff first.

I saw this thread and remembered that my battery light would come on when I accelerated hard, but the alternator gauge wouldnt go up or down and the truck never died afterwards. I didnt know if anybody figured out what it was.

Seen the battery light twice both times alternators, first in the Excursion then in the F250. Both times started loosing electrical stuff then the batteries just died.
Very easy to swap out alternators on the 7.3's.
