Hey guys new to working on fourwheelers just bought my first polaris sportsman 400. Its a 2004 model. Everything seems to work fine except my AWD doesnt engage i switch it on and everything spins including the front drive shaft so it seems the front diff isnt engageing. Ive read around on it on the forum still kind of lost and confused. The speedo doesnt work its currently unplugged as the previous owner did that. He said the awd worked for him so either hes yankin my chain or somthing just went bad on it. All the wires seem connected down by the diff theres a few random orange wires by the main cluster unplugged but thats about it. Any help would be great thanks guys.
