OEM Alternators

How an Alternator Works

Alternators charge the battery and power the electrical systems of your vehicle as the engine runs. By converting mechanical energy from the engine into electrical energy, the alternator ensures continuous power to the entire electrical system, maintaining the battery’s charge to start the engine and power the vehicle.

Signs Your Alternator Needs Replaced

When an alternator isn’t working, it can produce various symptoms. Here are a few common signs that indicate a potential issue:

  • Dim or flickering headlights, interior lights, or dashboard lights
  • Better warning light like “ALT” or “GEN”
  • Difficulty starting the engine
  • Issues with power windows, seats, infotainment system, or other electrical accessories
  • Unusual noises like grinding, whining, or squealing sounds
  • Burning rubber smell from the engine
