I think the high idle and cold timing advance get power from the same source, so its possible the cold advance would also have to be disabled. Normally these parts should only get power when the engine is cold and the ignition is one. Why would anyone want to hard wire it so its always one?

If you don't have time to fix it, you can simply unplug them for now and the engine should still start and run well enough.

This is the temp switch that turns the power off when the coolant temp is over 112 degrees.



Power to the switch comes from the ignition circuit.
So there should be no power to the switch or fast idle/timing advance when the key is off.

I have to look up a couple things on the 85 harness.

i unpluged my high idle cause it idles way to high, and im even thinkin about unplugin the timing advance cause i think it is just workin against me. if i unplug my timing advance and high idle, adn disable my glow plugs mine will still crank quick that when yours did in your video, but my timing is more advanced than stock, and my pump is turned up a little bit. this morning it was 13 cranked my truck instead of smokin a white blue smoke mine smoked black and had a lope kinda like those hot rod diesels

Last time I heard a price, I think that switch was about 45 dollars.

The switch turns the high idle off on a hot engine, on on a cold engine.

So if someone is feeding battery power straight to that switch, it will turn on when the engine temp gets below 112 degrees.

Check you engine harness connector, I think you have an 8 position connector with 7 wires going to the engine.

Orange with white stripe - glow plug power, 2 of these
Red with black stripe - engine overheat
White with red stripe - oil pressure
Red with white stripe - coolant temp
Green with red stripe - ignition power
Purple - glow plug trigger wire

Your cold advance is staying on when it shouldn't. Mine would do the same when I didn't have a diode for my manual high idle switch, once the engine got nice and warm if I'd hit that switch the cold advance would come on with the high idle and the engine would enter a semi-runaway mode, it'd revv up to past 2000 rpms, then drop way down to below low idle, barely recover without stalling, then off it went again. I was actually very unhappy with the stock high idle capabilities, I was idling at 750 rpms low and could barely get up to 950 rpms high, I had to modify the linkage so I can stay at 650 rpms low and still hit 1100 rpms high. If you unlug your cold advance, and plug the high idle back in, what engine speed are you seeing?
