What is a Car Alternator?

You will typically find an alternator bolted to your engine in your vehicle. The alternator has a pulley on it that is driven by a serpentine belt via the crankshaft pulley on the engine. The alternator supplies DC voltage  to the vehicles electrical components such as headlights, radio, power windows, windshield wipers and dashboard accessories . The alternator also supplies the vehicles battery with voltage to be stored internally. 

Alternators can last the lifetime of your vehicle, but like many vehicle components, they are prone to general wear and tear. Overuse, heat damage, faulty internal parts, water exposure, or damaged wires can shorten the life of your vehicles alternator.

  • Your battery keeps dying 
  • Dim or unusually bright dash lights or exterior lights 
  • Trouble starting vehicle Battery light lit up on vehicle dash
