NEED HELP WITH WIRING. THE SWITCH OHMS OUT GOOD BUT IDONT HAVE ANY POWER AT TRANS. .ANY HELP WOULD BE GREAT.  

Need help troubleshooting the same problem.  4wd will not kick on.  light at switch will not come on.  any help appreciated  99 500 sportsman  

I have a 97 500, same problem? just wanted to no if you figured it out? If I'm plowing snow, it is two wheel,but,after a half hour it starts to work. If I put it back in garage for a little bit you get to start over.
Let me know if you figure it out. If I find something out I will pass it on.  

Have seen this happen before.  I would say that your speedometer is bad.  Does the reverse overide switch work when pushed?  If not then I would say you will have to replace the speedo.

My 99 did the same thing back a few years ago, replaced speedo and everything was fine.  

Sorry was out of town. yes, the override works. doe's all of the wiring run to the speedo? This machine has 1200 mile on it. Its like new. The guy I got it from had it up north and did not use it very often.  

Did you check the fuses or breakers.
I have a similar problem but my switch lite is on, but only the right front and left rear wheels spin it gets stuck everywhere.. can anyone help ?  

I have a 99 sportsman and have gone through 2 speedometers.  The AWD is electronically activated through the speedometer, so if the speedo doesn't work the AWD won't either.  I just wonder if there is problem with wiring that causes these years to fry speedomters.  After the second one blew I tried to bypass the speedometer to no avail. If anyone has any ideas that would be great  

O.K, but why do you think that after I drive it. It starts to work? Could this be also do to the speedo?
