My sons quad started acting up at camp the other day it will start and drive then quit just like the key was shut off now it will run but when I hit the 4x4 button it quits if anybody has any ideas let me know. Thanks
Hopefully, you don't have a short or bad connection. I've seen kinda goofy things like this happen to a Sportsman with a bad stator and/or voltage regulator - it's easy to check, so I'd start there. I found you a link with some info: Stator Testing? sportsman 450 - Polaris ATV Forum
