I need a little help. I have checked every thing i know to check and so far I have not found anything wrong. My voltage to my front diff. was 12volts. I have 23 oms., checking my magnet in the front diff. I then remove the front diff. and to my surprise the spraig is ok...When my 2009 rzr-s was new i could push the AWD switch and climb my steps,(the front diff was locked in). When i jack up the rzr or the diff. seems to be working, But it will not engage trying to climb my stairs? Is it possible for the spraig clutch to be slipping? There are about 400 miles on my rzr-s. A little help please!!
