George: you said:
"but the trick is that to disable it, you need to provide constant 12V to that solenoid when the key is on -- not disconnect it. Running with it disconnected will cause the timing to always be excessively advanced, which has detrimental long-term effects."
But I thought it already had constant power to it when the key is on. My interpretation of the D24T glow plug wiring schematic shows that it shares a circuit with the pump shut off solenoid, which is hot with key on, of course. Is there an external switch in the circuit? Forgive me if I sound stupid, but I'm confused. Thanks.
