The alternator helps to recharge your battery when the engine is running and power all of the electrical systems in your vehicle. It does this when the engine belt turns the alternator shaft. This converts the mechanical energy from the engine into electricity.

They are simpler and lighter than the DC generators that some vintage automobiles used. They are easy to recognize, since they look like little fans with a metal cage.

Alternators are one of the more common parts to be replaced as your truck racks up the miles over its lifetime. Good signs that it is nearing the end of its useful life are when your lights go dim while driving at night, or if your battery can’t seem to hold a charge.
