I need help! I keep blowing up alternators and can't figure out why. I assume that I have a short because when the car sits in the driveway the battery dies. I think I may have found a wire that is rubbing and I fixed that. I charged the battery. Before I put a new alternator on, I let the car sit to see if the battery held a charge. It sat for two weeks with no problems. I put a new alternator on and the first day it ran fine. When I started it the next day, the volt meter jumped up to 18. I didn't drive it and the next day the battery was dead again. Any suggestions?
