What Does an Alternator Do?

Closeup of Alternator

An alternator sends power to the car’s electrical system while the car is running. A lot of O'Fallon drivers believe that it is the battery that powers the vehicle, but that is not the case. The battery is used to start the car, but it is the alternator that works like a generator. Its source of energy is the gas engine in the vehicle. If you would like to know more about the alternator and its functions, do not hesitate to contact the team at Auffenberg Dealer Group.

Issues with the Alternator

If you think that there may be something wrong with the alternator in your vehicle, be on the lookout for the issues mentioned below. If you notice any of these problems, you can set up an appointment at one of our service centers:

  • Battery warning light is illuminated on the dashboard
  • Headlights and interior lights are dim
  • There is a burning rubber smell under the hood
  • Your devices will not charge
  • You hear a whining or screeching sound once you start the car
  • The car will not start

Is it the Alternator or the Battery?

It can be difficult to tell if there is an issue with the alternator or if it is a problem with the battery. There is a way to determine the culprit. You should wait until the vehicle is unable to start and then jumpstart the engine. If the vehicle dies right away, it is probably the alternator. If this is the case, you will want to have your vehicle evaluated by a professional.

How Long Does an Alternator Last?

You can expect anywhere between 80,000 and 150,000 miles out of your alternator. For most drivers, that means it should last somewhere around seven years. Your alternator could need to be replaced earlier depending on a few factors.

  • The quality of the alternator
  • The driving conditions in your area
  • The power drain on the alternator
