This thread describes a problem like yours: https://www.yotatech.com/forums/f116...glitch-182108/

You have a wiring issue, blown Alt 80 amp fuse, or a bad alternator.

 

my truck did that when the alternator was on it's way out....

 

did you loose power at the charge fuse?

 

i never tested anything. i knew it was the alt. when it went bad. the truck died at a redlight and wouldn't take a jump.

 

wish my truck warned me when my alternator went out. It died suddenly and left us stranded on a cold, rainy night.
