The function and purpose of Alternator.

Your engine's electrical parts are critical for regular daily operation. Your GMC Sierra 2500 HD alternator has a pulley that spins as the crankshaft spins because they are both connected by a drive belt. Inside that alternator, a constant supply of current for your car or truck is generated as a pair of metal claws and brushes spin around a coil; creating a powerful electromagnetic field. The energy from your alternator continuously charges the battery, and at the same time distributes current to the climate control system, stereo, headlights, and plenty more on your GMC Sierra 2500 HD.

There's no better place for thousands of items to choose from.
