How does a kill switch work on a four wheeler?
The kill switch is usually wired to the ignition coil. The ignition coil is part of the ATV or UTV that sends a spark that ignites the engine. The kill switch breaks the ground circuit so that the coil no longer has a positive and ground. Because of that, the ignition coil is no longer firing.
What to do if your Polaris won’t shut off?
I have a 2004 Polaris 550 Classic. When its running and I hit the kill switch or turn the key off it keeps running. The only way I can kill it is to choke it.
Why is the ground command not working on Polaris?
If you have access to a multimeter, you need to verify that there is ground present at one side of both the ignition and kill switch. You can then trace this back to the CDI box. If the CDI box is getting the ground command from both the key in the off position and from the kill switch when applicable, most likely your CDI box is failing.
What does the CDI box do on a Polaris?
Both feed back to the CDI. The CDI box has multiple functions, one being to shut the motor down (kill the ignition) when it receives a ground command from either the kill switch or key switch. So one of two conditions are likely.
Can a switch or kill switch shut the engine off?
It is a 2001 model year if that matters. Re: switch or kill switch will not shut engine off… If I am thinking correctly, you should have a black wire with a yellow tracer, going to the power pack. That is the ground circut for the ignition system.
