My son has a charging problem, he has gone thru 2 brand new batteries in a weeks time. He said they took the battery terminal off and the car stayed running is that a good indication the altenator is still good or not? He has also blown 2 main computer fuse in the last 3 months, which leads me to believe sometthing other than the altenator is the problem,and I know nothing about foreign car. Any advise is appreciated.
