OEM Porsche Alternators

What is an Alternator?

Simply put, the alternator is one of the parts needed to provide electrical power in your Porsche model. It creates electrical energy from mechanical energy with an alternating current. For example, the alternator powers your headlights, heated seats, car radio, and even the windshield wipers.

How Can I Tell If My Alternator is Going Bad?

If your alternator is starting to go bad, your car battery will have to work harder. On average, an alternator can last anywhere between 7 to 10 years. The best way to avoid this is to watch for some warning signs. These signs may include:

  • Dim or very bright headlights
  • The power windows or locks stop working
  • The entertainment system is acting up
  • A dead car battery
  • Battery warning light on the dashboard
  • Unusual growling sounds coming from the engine

If you think your alternator might be failing, the best thing you could do is test your charging system. You can also take a look inside your owner's manual for more information.
