    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?

    Is there any where else $116 for wires?

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

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