Have an 08 Sportsman 400 HO. AWD did not work when I got it. Took apart and found the thrust button assembly was missing? Think it just wore down and got ground up. Anyway, bought a new one, inspected everything and all looked fine otherwise. I wasn’t sure how tight to make the thrust button so I just turned the Allen screw until it was snug after re-assembly. Put it back together and still no AWD. I get 13V at the plug with the AWD switch on and I get 23-24 ohms on the coil when I test it. Any ideas as to what else I should check? Can’t find much info on this machine on any forums. Any help would be appreciated!
