Alternators

Your battery may start your vehicle, but it's actually the alternator that makes it possible in the first place. The alternator does two things, and it does them well. It's responsible for charging car batteries and powering electrical systems. That means you enjoy full use of your headlights, entertainment system, power windows, windshield wipers, and more.

How Alternators Work

The alternator converts the mechanical energy of the engine into electrical energy. The engine uses belts to move a pulley that turns a rotor shaft. The shaft spins magnetic coils to generate AC power. A rectifier collects that and transforms it into the DC power many of your electrical systems use.

Learn the Signs of a Failing Alternator

Sadly, even the best alternator can go bad. Whether due to a bad jump start, parts wearing out, or an improperly installed accessory, that's going to cause problems. Symptoms include:

• Flickering headlights
• A dead battery
• Burning smells
• An whining engine noise
• Power windows stop working
