This diagram is the circuit wiring diagram of the Toyota 3-pin alternator. The alternator is connected with the battery, ignition switch, and ground using three wires. A red wire is used for a battery supply. It is also called a live wire. This wire connects the battery to the alternator. The white wire is connected to the ignition switch and the remaining wire monitors the battery charge level. All these components work coherently to make the alternator generate electricity.
