Original Porsche Alternators

Refine Results

Your Porsche model is equipped with an alternator. It helps keep your battery charged by supplying electrical current to your luxury vehicle. Alternators give power to the car radio, power windows and locks, the windshield wipers, and other parts.

How Do I Know If My Alternator is Going Bad?

Down the road, your alternator may start to show normal signs of wear and tear. When that time comes, you'll want to replace it before the problem gets worse. Luckily, a failing alternator is easy to spot. Some of these symptoms may include:

  • Dimming or flickering headlights
  • Whining noises coming from the engine
  • Power windows are not working
  • The entertainment system or electronics are starting to act up
  • Car battery is dead
