03 sportsman 500 (made 12/03, is this an 03 or 04?) the 4wd light flashs for less than a second in 2wd every now and then. what does this indicate? what repair manual is recommended for these machines?
thank you,

 

Any thoughts on this at all?

 

Well I post in the absence of others, I hear sometimes our Sportsman's
"Act up" whereby something is still reporting to be engaged in 4wheel/AWD.
I have heard about driving in reverse for so many minutes until disengagement.

You could let some others chime in here, as I have not had the problem and
only reporting what others have claimed. To be safe call your dealer or Polaris
and see if they confirm what I am saying or indicate some other problem.

Regards,

has the hub oil been changed?

 

I would start by checking the transmission switch. Sometimes they can become intermittent and make the bikes electronics think it is in a different gear, and thus turn off the 4wd, otherwise check the hub coils and wiring. Sounds like an intermittent problem. I am not that familiar with the 2003/4.
