    I have an M1090 dump truck. The PTO switch will not stay engaged (lit up) after 2 or 3 times raising the bed. Sometimes the switch wont even light up or engage. I am getting power to the switch. The fan also wont engage for cooling the hydraulic system under the bed. Could this be due to overheating, a safety mechanism, etc? I cant find a maintenance manual for the truck only a operators.
