    Is there any way to get pictures of what the wiring should look like. I’m building a kart out of a destroyed one and not sure where the wires should be. Thank you

    Where does the black and red wire plug in at . Mine spins over but will not fire an the red and black wire is not connected to anything.

      The black/red wire in the harness connects to the black/red wire coming from the stator via a bullet connection. This is the CDI power wire.

        It is coming out of the stator but not connected to anything else

    I have a 2007 jet moto 150 automatic atv. I purchased it not running. There is no spark. I have done dome digging and found it is the gy6 engine with the DC ignition. I have replaced the battery, DC cdi, ignition coil, and tried a new stator. Still no spark. I ran a ground from #4 on cdi to engine. And checked the handlebar switches. Here are the readings I have
    Blue / yellow from stator .16 vac
    Blue /yellow in to cdi from stator .15 vac.
    Cdi in #6 from battery 12vdc.
    Cranking voltage out to coil from Cdi .01vac

    I installed a new stator but got less ac output than the original. It is a 6 pole unit.

    I am at a loss as to what to try next. Can anyone help?


    I have a Yerfdog Howit 150cc LY6 3206 model. Does the GY6 engine wire harness match the LY6?

      Sure, if you want to keep the same problems you’re trying to fix.

      Proper electrical design and made in America isn’t cheap.
