Cannot Shut off motor at switch.

[7355hpchry]

I have a wiring SNAFU. My 1980 DT65 will not shut off at the ignition switch. I have to choke the motor till it floods out, to kill it. Some knucklehead in the past has bypassed both the kill switch and the neutral safety switch.

Right now, the Brown wire from the ignition switch control box has been cut at the motor connector. A wire has been spliced into it that runs to the starter relay. The Brown wire should run power to the neutral saftey switch. Also the Yellow/Green wire on the motor harness is not connected to anything. The Yellow/Green wire is from the neutral safety switch.

The kill switch has a Black and a Green wire coming out of it. These wires are just pigtailed together and loop to a green wire in the main harness. There is no power in this green wire at all.

How do I get this back to acting right so it shuts off with the key?

I have the high dollar factory SUZUKI manual for this motor but the wire diagram sucks.

Re: Cannot Shut off motor at switch.

Update!! I now know why the kill switch was bypassed, the top was lost and the switch is no longer available. It also looks like the ignition switch was replaced at some time as the wire colors from the switch do not match the engine harness.

What wire is grounded to shut the motor off??
I cant understand by looking at the wire diagram how this engine is able to start and run. According to the diagram, the wire that is supposed to be used to feed power to the CDI is routed through the kill switch. On my motor, it is not connected to any power source, it's just looped back to it's self.
