What Does an Alternator Do?

An alternator sends power to the car’s electrical system while the car is running. While many drivers think the battery powers the car, it’s only used to start it. The alternator functions as a generator, using the gas engine as its source of energy. For more alternator information, turn to the service center at Honda North.

Common Alternator Problems

If you’re worried that your alternator is in need of repair soon, it may be time to take a trip to Honda North. These are a few symptoms to look out for:

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

How Long Does an Alternator Last?

Most alternators last between 80,000 and 150,000 miles, or about seven years. However, some factors can cause your alternator to wear out prematurely:

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

Failing Alternator or Failing Battery?

Many of the signs and symptoms of a failing alternator are the same signs and symptoms you will find when your battery is failing. The easiest way to tell is to jump start your engine, then remove the jump cables after it starts. Does your Honda car die immediately? If so, the issue is most likely the alternator.
