Understanding the Importance of an Alternator

When I first learned about car maintenance, I quickly realized that the alternator is crucial for my 2002 Chevy Silverado. It’s responsible for charging the battery and powering the electrical system while the engine runs. Without a functioning alternator, my truck would struggle to start and could lead to more significant issues down the road.

Signs of a Failing Alternator

Before purchasing a new alternator, I made sure to look for signs of failure. I noticed dimming headlights and strange electrical issues, such as my radio cutting out.
