1998 Polaris Sportsman 500, the 4wd works fine in forward drive but, the 4wd won't work in reverse. It use to work when I engaged the reverse override button but, now the rear tire are the only thing spinning, 2wd only. Can anyboby help troubleshoot this?

 

Welcome to the forum *****. Does the rev override work at all? Can you go fast in reverse when you hold the button? If not, that's where your problem is, the switch or wires.

 

JumboFrank,
Yes, the rev. override works fine. I can go fast in rev but it is only in 2wd while the 4wd button is engaged. It started to get flakey last winter, somtimes it would engae in 4wd in reverse and somtimes it wouldn't. If I would just keep pushing the rev override it would eventually engage 4wd and away I would go. This year I can't even get it to engage in 4wd in rev at all.

 

check the contacts of the wire to make sure thier not corroded and then maybe check the transmission switch which tells the bike what gear its in to prvent the awd not to work unless the override is pushed. these 2 things work together to make it work correctly.
