Despite this drawing representing what an actual HD wiring diagram shows, the Voltage Regulator is shown connected to the wrong side of the Main Circuit Breaker. For the sake of safety, ALWAYS connect the Voltage Regulator on the opposite side of the Main Circuit Breaker from the side where the battery is connected. Please remove the Voltage Regulator connection & reconnect it to the opposite side of the Main Circuit Breaker if your bike is wired as shown on this & the HD wiring diagram.
