Have you checked for leaks? Something must be leaking

battery, voltage regulator or stator

Belt. Change your belt and ensure that water isn't getting in there. If it's wet or destroyed it will do that.

Sounds like something electrical is getting wet. in your shop , or driveway , start quad and run up till it's warm. Then take a spray bottle and spray all electrical connections starting from the bottom and work your way to the top. theres lots of connections on these quads. It's going to take some tome unless you get it to duplicate what it does on the trail. When you find the culprit use Dielectric silicone to water proof the connectors . Good luck . thats about the only way to go about this reapair , it takes patiance and time

is your belt contaminated with oil . sounds like its slipping take of belt cover and inspect belt and crank seal , clutch seal.on engine

If the shocks are worn out, get off the machine and lift up on the back rack. This takes up the slop between the shifter box and the transmission, and usually allows me to shift. I also had an issue with the thin steel plate behind the shifter box. Got a crack in the top , so it was flexing, creating more slop. Welded it shut, good as new.
