Charging System
A Charging System is a crucial part of any vehicle that keeps the battery powered and provides electricity to all electrical components. It's like the power plant of a car, consisting of the battery, alternator, and voltage regulator. When mechanics mention working with charging systems, they're talking about diagnosing and repairing these components that keep a car's electrical systems running. Think of it as the system that makes sure your customer's car battery stays charged and all electrical parts like lights, radio, and power windows work properly.
