What Does an Alternator Do?

February 8th, 2019 by

Vehicle Alternator

The alternator sends power to the vehicle’s electrical system while the car is running. The battery will start the car, but it doesn’t power it. The alternator functions as a generator, and it uses the gas engine as its energy source. For additional information about the alternator, visit the service center at Libertyville Chevrolet.

Common Alternator Issues

Are you concerned that you have a faulty alternator? If you are noticing any of these items, visit Libertyville Chevrolet near Waukegan:

  • Battery warning light appearing on the dashboard
  • Burning rubber smell under the hood
  • Devices not charging
  • Dim headlights or interior lights
  • Unable to start
  • Whining or screeching sound after the vehicle has started

Failing Alternator vs. Battery

Many drivers mistake alternator failure with a failing a battery. If you’re looking to see which one is causing the issue, wait until the vehicle doesn’t start and a jump is needed. Jumpstart the engine, then remove the jumper cables. If the vehicle immediately dies, the problem is most likely the alternator. To have a certified technician inspect your vehicle, schedule a service appointment at Libertyville Chevrolet near Gurnee.

How Long Does an Alternator Last?

Alternators typically last between 80,000 and 150,000 miles, or about 7 years. There are instances that cause the alternator to wear out earlier:

  • Power drain on the alternator
  • Alternator quality
  • Driving conditions
