Audi A4 AlternatorThe automobile alternator is an electricity-producing generator. This is how mechanical energy converts to electrical. Although the car battery does provide electricity, the electrical mechanisms in a given vehicle need the uninterrupted stream of power provided by alternators. The alternator is simply a mechanical device that consists of a pulley, wheels, wires and brushes that flows to the battery via the crankshaft.

An alternator translates motion into an electrical current when your vehicle is on the move. Your windshield wipers, defogger, cooling fan and the radio all receive power from this current.

With an Audi A4 it is recommended that you or a licensed mechanic inspect the alternator and related parts periodically. You will still get electricity until it is drained directly from the battery through the car even if the alternator malfunctions. Some model years of the Audi A4 have the alternator in an easily accessible location. Special tools are necessary if you are working with the alternator.
