My 2001 polaris sportsman 400 speedometer doesnt work. Its was working but stopped. does anyone know why or how to fix it.They cost over $300 new

 

Is the display blank or does it just not register speed??

 

just speed..the hours and miles light up..not sure if they change cause i never pay attention

 

someone said there is a speed senser in the front hub..is this true and will that cause it not to work

 

Hall effect sensor shorting out was the most common cause that I had on speed not registering. You can also check for any mud or dirt that may be blocking the signal from the sensor cap.Plus simple thing like the connector loose at the speedo itself.

If your AWD works its not the speedo.
My speedo does not work and I know its just the wheel sensor(Hall Effect). I just did not bother with it since the wheel sensor in Canada cost $80. I,d rather spend that on gas.
Not like their is and speed limits to follow in the bush.

Even if it was your speedo you can bypass it to get your AWD back without buying a $300 speedo.

 

everything else works..my four wheel drive didnt work but someone had the ground wire pluggged in to the center plug of the high beam..i moved it where it was suppose to be and it mad the four wheel drive work and my high beam is bright now. The speedo did work for a day but now dont..

 

When my wheel sensor started acting up the speedo needle would work once in awhile before it just stopped for good.
The senor is in a god awful place for dirt and mud next to the front brake rotor.
Even if I changed it I think it would not take long to screw up again anyways.
My speedo is so fogged up anyways I could see anything on it even if it did work. LOL

 

so can i take this off and clean it?

 

You can try to clean the senor and it may come back from the dead. I have heard of it.
