What Does an Alternator Do?

What does an alternator do? Many Farragut drivers believe that their car battery powers their Mitsubishi, but the battery only starts it. The alternator powers your car’s electrical system while you’re driving through Sevierville and beyond, playing an essential role in the functioning of your vehicle. The alternator is a generator for your car, using the engine as its power source.
