Chevy Cheyenne 3500
I have a 1998 Chevy Cheyenne. I recently started having issues with my battery/alternator? I’m not sure. But I left my headlights on one day and it drained the battery. Then I had to jump it to start it and it started fine. But then on my way home I got a red light and the battery gauge started to die. And then the truck just died. I tried to jump it again and once again it would start but as soon as I took the cables off it would die again. Would like to know what it could be.
