Hi, Spider Monkey; First, it's not a good idea to 'jump start' a car anymore. Computer damage can result. You will need to have the battery fully charged, then tested. If it tests okay, then have the alternator tested. You can't accurately test the alternator with a low or faulty battery. If the alternator tests bad, make sure it is getting a 12V source (some are fuse protected). Please reply with results.
Thank you. Loren
I have a 2001 vw 1.8t recently the battery light came on and then lost power and died. i can jump start the car and the clock and radio keep the memory. But when i jump start it the rpms eventually freeze and the gas pedal will not rev the rpms. Both the battery and alternator are testing dead. I was wondering if anyone could tell me if this is a dead alternator issue, battery, or aomething in the computer syste?m
