Audi B5 A4 30V 120amp Alternator

Car not starting? Battery not charging? Start here.

If you car won't start or the lights dim and the car dies, there is a good chance your alternator went bad.

The alternator in your vehicle keeps the battery at full charge when your engine is running. Because all of your electronic systems run off of this small piece, it's important that it is operational. If your lights are dim while driving or your battery dies within minutes of starting your car, it's time for a new alternator.
