I have replaced the cab on my m1008. Went to start it yesterday and the glow plug solenoid does not come on and I have no "wait light". I took a jumper from the top post of the solenoid to the smaller post below it and can jump the solenoid making the glow plugs come on and the engine fires right up. The high idle works when the key is turned but its not sending power to the glow plugs. If you are jumping the solenoid and try to turn the key it kicks the solenoid out. I looked at the wiring diagram from cucv electric and it is wired correctly. Before I removed the old cab everything work properly as it should. Only thing that is different from the new cab I put on from the old one is the wiring harness inside the cab and the fuse box.
