RockWire: Rockin’ 101

Demystifying Your Vehicle's Electrical System

When you turn the key and hear a click—or nothing at all—it is easy to assume your battery just died.

But the reality of modern vehicles is much more complex.

Today's cars are rolling computers, and your battery, alternator, and starter operate together

as a complete, interconnected power grid.

If one link in that chain fails, the whole system goes dark.

We built Rockin’ 101: The Power Grid to explain some common misconceptions

about automotive batteries and your vehicles starting and charging system.

As we grow more videos will be added but this one is the most common so it seemed like a good place to start.

Thanks For Watching!
