Do you know anyone who builds computers? If so have them look at ECU and see if they can identify problem.I have considered a direct wire to the glow plugs last year. It’s not a novel approach, but I believe when you disrupt the glow plug circuit it may derate the tractor.
Right now, the ECU is still reading the air and water temp sensors, but something else in the ECU circuit won’t turn them on. When I removed the water temp sensor plug from the water temp sensor in the glow plug wiring harness circuit, the tractor went into a derated mode.
What I think might happen is when the ECU sees the glow plug wiring circuit disrupted it will derate. I don’t know for sure.
I guess there’s only one way to find out…..
If I can fool the ECU into seeing both sensors, it may be possible, but I think any part of the harness not reading causes derate.
