    I want to make the lights work on one of my Motoplat equipped bikes but someone has kindly cut and discardeD the wiring, all I have is a yellow wire from the generator. I have had a search but I am struggling to find any wiring diagrams. Could any one point me in the right direction please?

    The yellow feeds into the voltage regulator (to cut the volts down to 12v). Power is then taken from that for lights etc. Attached is wiring diagram.

    Kind regards

    Thanks Lucien, I assume by the voltage regulator you mean the small square alloy block?

    You will only have a single yellow wire out of the Motoplat. You hopefully also have the wire to the coil as well

    116.JPG 117.JPG Making some progress, got a regulator from another Husky but it has two wires, what purpose does the black wire serve please? I assume the yellow wire is just teed into the lighting harness which is fed by the yellow wire from the generator?

    I put one on mine Steve. Cannot remember how many wires it had. I can whip the tank off and have a look if you want.
    Bought mine from Electrex World. Saved me a fortune in headlight bulbs !
    At a guess, with a two wire system, one goes to earth and one tee's into the feed. Let me know if you want more info.

    Thanks for offering, but then I remembered my 430 had completed two H&H,two scrambles and several practises with the headlamp on, all on the same lamp!! So I took the tank of that and too be safe borrowed her regulator!! My lights work now, just the brake light to sort:)
