Two Wire Alternator Voltage Regulator Wiring Diagram. Connect the positive wire from your regulatorrectifier to the positive terminal on the battery and the remaining wire to a ground. In the most basic terms it consists of two electrical contacts switches which are opened and closed turned off and on by two sets of solenoid coils.
Check the connections in that part of the circuit for a loose wire corrosion at the connectors or wiring damage that may prevent proper current flow between the battery and alternator. Always consult the wiring diagram. The red colored wire is usually the wire that provides power to the regulator.
My shriveled up old brain doesnt remember if the light turns on or off when charging though.
Tech b says that in many cases each wire in wire harnesses use two colors. One red lead from regulator rectifier to red connector output lead. Identify the third wire which is typically two wires with a snap in plastic connector on the alternator end. The voltage rectifierregulator is us and i cannot source an alternative.
