Your car's charging system is composed of three parts: the voltage regulator, the battery, and the alternator. The alternator and battery work together to power the vehicle's electrical components, such as the exterior and interior lighting and the gauge cluster. The alternator derives its name from AC or alternating current.

On most cars, the alternator is found at the engine's front and is crankshaft-driven. The crankshaft converts the up/down movement of the engine's pistons into circular motion. Certain older-model vehicles in Cicero used drive belts that ran from crankshaft to alternator, but most of today's vehicles have serpentine belts that are driven by the crankshaft. Your alternator is probably mounted to the engine with brackets; one of which is fixed and one of which is adjustable for drive belt tightening.

An alternator produces AC power, channeling it into the car's battery and providing the voltage needed to run its electrical systems. If your alternator isn't doing its job, visit Burdick BMW for service.
