Author Topic: Voltage Regulator (Read 6569 times)

I ordered a replacement voltage regulator for my 77 MGB through Victoria British. The regulator presently on my alternator has only two wires - a black and a yellow. The replacement (from SENTEX, Fair Sun Industrial Co.) has four wires: black, yellow, red, and white. Does anyone know where I can get a schematic as to how to hook this replacement up ? Although I rechecked the part number, could I have gotten the wrong regulator ?

Thank You

John

The internal regulators on the Lucas alternators vary greatly are really serial number specific. Many will work interchangeably, but certainly not all. My advice would be to take it to a Lucas-knowledgeable alternator shop either for advice or proper repair.
