Request for some diesel engine
I've tested the solenoid circuit, and the voltage rises from 1.45 V to 14.5V when the stop button is pressed, engine
running. I conclude that the problem is not a faulty circuit preventing the engine from stopping, but the stop solenoid.
The shop manual doesn't cover the solenoid, any issues with unscrewing it? Is it easy to drop in a replacement?
The tacho has also stopped responding. Are there any common failure points? I will check the connections on the back of the instrument panel and the wiring
harness. Any other obvious failure modes?
