Q: Door & trunk ajar, brake and battery warning lights come on while driving off and on. Alternator tested good & bad.

asked by on

Head lights go dim when all warning lights come on. Stopped at gas station. Car wouldn't start. Battery was dead. Battery tested good. Alternator tested bad at autozone but good at advanced auto. Can an alternator "not charge" intermittently?

My car has 225000 miles.
My car has an automatic transmission.
