  1. Hi I got a 5 wire rectifier. My red wire got a constant 12volts even when the bike is off. Is that correct. My black wire that must go to the ignition does not give 12volt if I turn on the ignition. I keep on blowing my rectifier. The fact that I have 12 volts permanently on the red that should be charging my battery tells me I got a short in that line. Thanks

    1. Your red wire is constantly showing 12 volts, even when the bike is off, suggests that there may be a short circuit in that line. This could be causing your rectifier to blow and preventing your black wire from getting the necessary 12 volts when the ignition is turned on.

      I would recommend checking your wiring and connections to ensure that everything is properly connected and there are no loose or damaged wires. It may also be helpful to check the resistance of your red wire to see if there is a short circuit present.

  2. Ok I have a 6 pin regulator it has 3 yellow, 1 black, 1 brown, and 1 w/ red stripe I need to know what goes where the three yellow go to the stator I’m thinking but the other three I haven’t a clue can you please shed some light on this for me.
    Kindest regards,

    1. Certainly, I can help you with the wiring of your 6-pin regulator. It appears that the three yellow wires should indeed connect to the stator. The black wire typically connects to the ground or a common ground point. The brown wire is usually associated with the ignition or power source. Lastly, the wire with the red stripe typically connects to the battery positive.
      Please ensure to double-check your specific equipment or consult a professional if you’re uncertain about the connections. Safety is paramount when dealing with electrical wiring.

  3. I’ve got a 6-pin regulator with black, pink, green, yellow then green and black.
    I know the yellow and pink are from the alternator and the last two go to capacitor.
    My problem is: which is the hot DC?
    and: the first BLK and green, which is ground and/or third fase from alternator?
    For reference it’s a shindengen sh542b-12.

    1. To determine which wire is the “hot DC” or the positive voltage output, you can use a multimeter. Set the multimeter to measure DC voltage, and with the vehicle running, check the voltage between one of the green wires (from the second pair going to the capacitor) and a good ground (like the vehicle’s chassis). This wire should be the positive (hot) DC output from the regulator.

      To identify which one of the black and green wires from the first pair is ground, you can use the continuity mode on your multimeter. Disconnect the battery and then check for continuity between each of these wires and the vehicle’s chassis. The wire that beeps or shows continuity is the ground wire.
