This diagram shows the working of delco remy three-wire alternator incorporated into a car’s charging system. The alternator uses the energy of the engine to generate more electricity and stores it in a battery. Three main wires complete the circuit of the alternator. The red cable carries the power from the alternator to the battery. The white wire turns the alternator on when the car starts and the other wire is the ground to complete the circuit. This keeps the car’s battery charged.
