What Does an Alternator Do?

 
If you’re like many drivers in the Orchard Park area, you may be asking, “What does an alternator do?” The team at Robert Basil Buick GMC would be more than happy to answer any car alternator questions you may have. The car alternator sends power to the car’s electrical system when the vehicle is running. It is a common misconception that vehicles are powered by the battery. The battery simply starts the car. The alternator works like a generator and uses the gas engine as an energy source. Learn more about the alternator and how to diagnose potential problems with Robert Basil Buick GMC below.

Failing Alternator vs. Failing Battery

If the vehicle dies immediately after receiving the jump-start, a faulty car alternator is likely to blame.
