Inside that alternator, an electromagnetic reaction takes place that generates a constant supply of current for your vehicle. The energy from your alternator continuously charges the battery, and at the same time distributes current to the interior electronics, lights and turn signals, and any other electronic part on your GMC Sierra 2500.
