Engine won't turn off

I just bought a 2003 Sportsman 500. It starts and runs good. When I go to turn it off with the key, it wont shut the engine down.
Just wondering if anybody has seen this before.
Thanks

It sounds like you have a broken ground wire somewhere. If not that it's the key switch or cdi box maybe.

Common problem. It could be ground wire, or switch, or cdi. Often times if it's the switch you can turn it off very slowly and it will shut off at about 3/4+ rotation. Sometimes it's the ground from the cdi corroded and not making good contact so that you get intermittent shut offs. Other times it's the cdi itself which will usually show up as not shut off when cold but after warm up and fan cycles through on and off the machine will then shut down as it's supposed to. You just have to try and eliminate the easy stuff first (ie. grounds and switch) and go from there.

I had to replace the switch on both My 02 Sportsman 400 & My 02 Sportsman 500 H.O. if you turn it off slowly it will usually turn off got both New O.E. Polaris switches off eBay same seller around $50 including shipping.
