I am having problems with my 98 mustang after a recent wreck. someone stopped suddenly infront of me and i ended up rear ending the back of their huge truck. there was little damage to my right headlight and my air bags deployed but i was still able to drive the car home. then it wouldn't turn on the next day so i charged the battery and it worked, the next morning the battery was drained again. I just got my alternator fixed so i doubt it has to do with that, is it an electrical issue
