Vehicle Systems: Electrical Systems

The electrical system is definitely the most comprehensive and complex system in a truck, for it covers everything from the batteries to the lights. There are five basic systems within a truck's electrical system. They are the charging circuit, the cranking circuit, the ignition circuit, and lighting and accessory systems (which include the lighting, instruments, horn and windshield wiper circuits).
