Understanding the Role of the Alternator

When I first looked into replacing the alternator on my 2001 Chevy Silverado, I realized how crucial this component is. The alternator charges the battery and powers the electrical system while the engine runs. Without a properly functioning alternator, my truck wouldn’t start or keep its electrical components working.
