Talk to arctic bomb about the error you are getting he has a way to fix it. He says sometimes you're machine is wired different. Explain to him what is happening and he'll send you an additional harness.
Never had the light flash, but the other day I was running in the back of my property and had to go through a small mud hole. I tried creeping in 2wd to avoid a mud bath and of course I started to spin. I hit the 4wd buttom (of course I was stopped) an nothing. Still 2wd. Tried going in reverse a bit then forward again to maybe see if it just wasnt engaging. Nope. No 4wd. So after hammering it to get out of the mud hole and spraying mud everywhere after just washing the damn thing lol, I made it back to the house. Checked the fuses and found the 5a fuse of 4wd/2wd blown. Replaced it and all is well now, but why and the hell did it blow the fuse. I may have hit the button while rolling forward the other day, would this of caused it? I havnt even had the thing a week yet and already having issues. What gives? Anyone else have this problem?
I know its says not too, but in a two hour Ecors race this weekend, I shifted in and out all race plus practicing all weekend. I also do it when I trail ride, hit the switch before I hit the big water or mud hole then switch it back to 2wd on the fly. Drag racing, take off in 4wd then 30 ft out switch it back to 2wd to free up horsepower, works great. Not seen any problems. Plus have done it this way since 2007 on a 800 Renegade, no problems, the light seems to go out faster when you are rolling.
The 4WD indicator flashes on & off the dash frequently when 2WD is selected on both my 2012 Commander Limited and my 2013 Maverick XRS while "cruising" and I believe it is engaging briefly as I could tell this while turning sharp on pavement (30 mph) as it "pushed" when the light was on. Could this be a differential or sending unit problem? Seems odd that both my machines have the same problem?
