• Discussion Fanatics

    As you might assume, the concept behind a one-wire alternator is that there is a single wire used to connect the alternator to the battery. The voltage regulator is internal, and there are no other wires that need to be connected to your electrical system.

    How to Install a 1-Wire GM Alternator

    1. Disconnect the negative battery cable at the battery.
    2. Mount the alternator to the engine.
    3. Follow the battery positive cable from the battery to where it is connected on the starter relay.
    4. Reconnect the negative battery cable to the battery.

    Also Know, does a one wire alternator need to be grounded? REQUIRES A GOOD GROUND In order for an alternator to charge properly, an alternator must be grounded to the engine block. If an alternator has paint or clear- coat on the mounting surfaces, it may not be grounded and will not charge.

    Accordingly, how does a GM 1 wire alternator work?

    The only thing you need to hook up on a one-wire alternator is a charge wire from the terminal on the alternator to the positive terminal on the battery (or any positive battery source). Once the voltage regulator turns on, the alternator will remain on and charging until the engine comes to a complete stop.

    How do I know if I have a one wire alternator?

    You can verify its a one-wire by opening up the case and looking for the letters SE on the voltage regulator. If its already installed on the vehicle you have to polarize it the first time to get it to work. You just use a jumper wire to supply current to #1 or #2 connector on the side.
