Speedometer displays wrong speed
 

Tried to search this info, but no luck.

Purchased a new used digital speedometer and it is displaying the wrong speed and racking up my mileage like crazy.

Can any suggest how I can correct this problem. Not sure if my machine would have a sensor that might be bad....

The original display was part analog and digital the new display is digital only.

I have a 2006 Arctic Cat 500 FIS.

Thanks,
