Just bought a Quick Attach 73" Snowblower, It came in today and put the tool group wiring harness with the 2 buttons on the left joystick and rocker sw for the left panel. Not sure how to troubleshoot the plug! snowblower chute turns left and right with overhead switch on or off? What controls the chute deflector? Not sure if its the machine or the brand new blower?? Any help would be appreciated! Great Site!!!
