Will, need to pick your brain. Have a M1028 that the GPR failed. Got a replacement BWD GPR1 that wont work with glow plug controller. Has continuity between two small posts. The original GPR does not. It just quit switching. Do you have a brand and part number for a good heavy duty replacement? Cant read the numbers on the GPR in my M1009.
A while back you asked for info on my Jeep. It is fiber glass body , all of the hardware including the frame is stainless. Engine is a 6.2 Detroit with a turbo 350 auto.It weighs 4200 pounds an you have to be retired the to have the time it takes to make one. Or you have to be nuts. I thine I'm both!
