2001 polaris sportsman 90 will not shut down

I have a issue where the quad starts and runs but will not shut down with the key or kill switch.

If memory serves,there should be a black wire with a white stripe coming out of the CDI box. It may turn into solid black. This is the ignition kill circuit. When you turn on the key switch,handlebar switch to run and the safety tether is in place, this wire is grounded. In other words the wire must be grounded in order for the machine to run. When you turn the key switch off or the tether is pulled off, this circuit is opened,thus shutting down the engine. Since yours won't turn off i'd be suspect of that circuit be grounded all the time for some reason. Either a pinched wire,bad switches or somebody has been in there. A quick test would be to disconnect the black w/white stripe wire at the CDI box and see if the motor dies or if it quits sparking. Then all you have to do is check the circuit and find the fault.
