Alternator or Voltage Regulator? Burned two batteries in a week.
The 1996 Audi A6 Quattro cars battery gauge will jump up under acceleration but doesn't seem to hold charge even after long periods at high R P Ms dies at idle I had it tested at AutoZone they stated must be Alternator but the Voltage regulator much cheaper part and a fix I could manage, the alternator not so much . Any information as how to diagnose one from the other would be greatfully welcome.
Is this a good question?
