The alternator generates the electrical power to the car battery to power a cars electrical system. The Alternator is rotated by a serpentine belt that utilizes the circular movement of the engine crankshaft. This rotation winds a coil made of an iron core and copper winding on a rotor to generates electrical power.

Some common symptom of wearing or failing alternator are; Battery warning lights, car not starting, the engine stalls while driving due to loss of electrical power, dimming of the lights and dashboard or a winding noise while driving. It’s important to eliminate other electrical power supply problems such as batteries, cables and fuses that may be affecting the alternator’s performance. An example would be a bad battery or battery cables may effect an alternator test.
