What Does an Alternator Do?

Mechanic showing the cost of service to client

An alternator sends power to the vehicle’s electrical system while it’s running. Most drivers believe that the battery is what powers the car, but it’s only used to start it. The alternator functions as a generator that uses the gas engine as its source of energy. For more details about the alternator and what it does, visit the service center at Sunrise Chevrolet.

Common Alternator Problems

If you’re concerned that your alternator is on its way out, or you’re noticing the following issues below, visit our Chicago-area service department:

  • 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

Carol Stream-area drivers sometimes mistake a failing alternator with a failing battery. The best way to distinguish between the two is to wait until the vehicle doesn’t start and requires a jump. Then, jump-start the engine and remove the jumper cables after it starts. If the vehicle dies immediately, the issue is most like the alternator. Schedule a service appointment to have a certified technician inspect your vehicle.

How Long Does an Alternator Last?

Most alternators last around 80,000 to 150,000 miles; or about seven years. There are some factors that can cause your alternator to wear out early:

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