Can anyone give any insight on how to test the hall effect sensor. I have the plug removed from the back of the speedometer.

 

Had a harness tester for the hall effect sensor at the shop to accurately do this. If the speedo has all other functions except speed and mileage accumulation,almost guarantee it to be the hall effect sensor has shorted out.Replaced a bunch of these over the years.Item #40.http://www.cyclepartswarehouse.com/f...1999&fveh=5486 You can try to clean up around the sensor cap to see if that's the problem,but if it's not,here's the cheapest new one I've found so far,but still not cheap.http://www.shopsblogs.com/Genuine-Po...OR-LG-for-Pol/

 

You speak of a test harness. I want to test this sensor before I invest in a new one. How is this done?

 

This is the sensor tester that I had.https://polaris.service-solutions.co...x?id=105&cat=9 Plus I had an additional harness that plugged into this harness for testing hall effect speed sensors. You can test it with a meter if you have small probes that can go into the 3 wire connector(9 volts applied to the red wire,not sure about using 12 volts as used in the video) or peel back enough of each wire to allow alligator clips. Here's a video that's similar to your connection. The hall effect speed is internal on this one,but you can just spin the wheel to test. The holes and solid spots on the newer style rotors are what trigger the sensor to register speed,rotation speed used on the older solid rotors. If the meter doesn't change then the sensor is dead.

 

When the hall effect (wheel sensor) fails the only thing on the speedo that works is the hour meter and display lights.

My hall affect has been blown for 4 years now buts it not worth the $80 to me since the speedo glass is to foggy to do much good anyways.

If yours speedo was the problem you would not have AWD.
