In addition, the ground wire supplies the connection needed to return current from the alternator to the battery. Typically, this wire will be black and is located at the bottom right corner of the wiring diagram. The output of the alternator is electrically connected to the starter and the regulator, which supplies power to the rest of the vehicle. This wire will be green, and it will be at the bottom left of the diagram.
