Have been trying to narrow down the issue with no luck. I bought this RZR about 200 miles ago (1150 total miles now). 4wd starting flaking in R not long after I bought it, then in forward. Changed the fluid (fluid that came out was filthy) and it starting working most of the time in forward again, but not always. Still nothing in R. Pulled the diff, everything looked good. Cleaned it thoroughly and went ahead and swapped the armature plate with a Black Rhino plate while I had it open. Still no 4wd in R though.

Voltage tests at the plug and switch are good. Ohm test on armature is good, but it did fluctuate up and down (within range). Gauge cluster shows it’s in R, and shows the AWD indicator.

What am I missing?
