So What Does a Car Alternator Do?

Traditional gas and diesel vehicles use a battery to start, as well as to power various accessories. But the battery only has so much capacity – and if there wasn’t some sort of recharging system, we’d be recharging and replacing batteries on Morgantown roadsides all the time! The car part known as the alternator is what solves this problem, converting mechanical energy into electrical energy that’s used to power accessories and recharge the battery while your vehicle is running.

What Are the Symptoms of a Bad Alternator? 

If your alternator is on its way out, there are a few symptoms that should be fairly easy to recognize. If you notice any of these issues, schedule a service appointment with our team of certified mechanics today!

  • 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
