Customer Questions

Will the alternator drain my battery?

Which alternator system is controlled by the PCM?

How do alternators work?

Alternators convert mechanical energy from the engine into electrical energy to power the vehicle's electrical system and charge the battery. They consist of a rotor, stator, and voltage regulator, which work together to produce electrical energy that is used to power the vehicle's electrical components and charge the battery.
