2007 Polaris, Speedo showing speed while sled is stopped

[polarbear]

Anyone have any thoughts on this. While my sled is stopped it will randomly show a speed reading, anywhere from 3mph to 12mph on the digital side of the gauge pack. Any ideas why this might be happening? The sled is a 2007 Polaris Switchback 600 CFI.

I have the same issue, took the sensor apart at the axle and cleaned all the grease off of it, no difference. I have a new sensor on order $60. Will post results.

Well I found the problem. The wire which runs behind the secondary clutch up to the wire harness came loose and was rubbing against the secondary clutch. The wires were exposed and shorting out. All I did was tape up the wires and rerouted them away from the secondary. So far, its fixed my problem. No more miss reading on the speedo.
