Genuine OEM GM Alternators

The alternator of your vehicle is essentially a miniature power house that helps charge the car battery while you drive.

How does a Car Alternator Work?

The alternator motor works in conjunction with the serpentine belt to charge the battery while the vehicle is in motion. As the engine runs, the serpentine belt, which is connected to the crankshaft, drives the alternator. The alternator then converts mechanical energy into electrical energy, producing an alternating current (AC) that is converted to direct current (DC) to charge the battery.

The alternator has an internal voltage regulator that regulates the electrical output to ensure the battery is charged at the proper voltage. It also powers the electrical systems of the vehicle while it is running, such as the lights, radio, and other accessories.

When to Replace an Old or Broken Car Alternator

Signs of a failing or dying alternator include dimming headlights, a battery warning light on the dashboard, a dead battery despite recent replacement, unusual noises coming from the alternator, and electrical issues such as flickering lights or malfunctioning accessories. If you experience any of these signs, it is important to have your alternator checked and replaced if necessary to prevent a complete battery failure and potential breakdown.
