STARTING AND CHARGING SYSTEMS OVERVIEW
Starting and charging systems can be located on the engine block, typically in the front area of the engine. This source of power supports important electronic devices, such as the ignition and fuel system, windshield wipers, radio, air conditioning unit, power windows, power seats, moon roof, headlights, central computer and much more.
The main components of charging systems are the alternator and the regulator.
- The alternator is the device that creates alternating current (AC) and converts it into the direct current (DC) that all vehicles require.
- The regulator is the device that controls the voltage level throughout the vehicle.
In addition, a system of pulleys power the alternator and other parts of the vehicle by using a serpentine belt or multiple separate belts. These belts are wrapped around the pulleys and rotate when the engine is running, charging the car battery and powering the vehicle’s electronics.
