I have a 2008 Polaris 800 EFI HO. I just changed the voltage regulator but I am having some other issue now. Here’s the issue. I had some issues before which lead me to changing the regulator. The 4×4 stopped working when that was bad. I flipped it and I put it up on blocks and tested it. The 4×4 works yaaaaa, and tested everything up on blocks. The 4×4 worked…..on the blocks. Tested it on the trail today and low and behold the 4×4 didn’t work. Put it back up on blocks and the 4×4 is working again. Under power the wheels don’t work. Please don’t tell me it’s a transfer case issue????????
