The function and purpose of Alternator.

Your engine's electrical parts are critical for regular daily operation. Your GMC Sierra 1500 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 goes back to the battery and keeps it charged, while also supplying voltage to circuits that power your interior electronics, lights and turn signals, and any other electronic part on your GMC Sierra 1500.

There's no better place for what you are looking for.
