    So that means to stop engine the pulser coil output should be grounded via kill switch button?

    Won't that cause sparking etc? As we are dumping the current from the pulser to ground.

    Also I searched few pinout pics of 4 pin cdi and they say switched 12v what does that mean?

    The black with white stripe killswitch wire will need to be joined to the black with yellow stripe wire for the coil positive. Then just run the green wire to the other greens or earth on the frame or engine. Without worrying to much about the black with red stripe get a multimeter and put it on the battery terminals to see if the battery is charging. If it is charging it will fluctuate between 13 volts and 15 volts.

    If it ain't broke, break it.

    As this pic here shows blue with white in a 4 pin is the main wire to join to your killswitch but you can also use the black with yellow stripe.

    Got it. This picture explains it.

    So there are three variations of kill switch. Either insert kill switch inline with the 12v feed to cdi, or ground the pulse coil output ( which is hardly 2 volts I think) or ground the Input to the coil (200 volts ac).


    I am a bit skeptical in inserting the kill switch inline to the input of the coil as the Input voltage to the coil are 200 volts so don't want to switch on/off across 200 volts...

    Just curious we are dumping the current from the pulser coil to the ground which essentially causes the engine to cease won't it cause any problem to the pulse coil?

    Many diagrams I see online for dc cdi shows the 12v feed to cdi as switched 12v so I assume that's much good and safe route as we are just disconting the power rather then dumping it.

    It's very common to hook the killswitch up to stop the motor thru the stator pickup mate. Won't hurt anything.

    If it ain't broke, break it.

    Thanks will do it. And update of I see Amy improvements in using dc instead of ac
