One more thing; what's connected to terminal 30 of the governor relay?

It sounds like you have a number of issues going on at the same time, it's going to take some time to sort through all this so be patient. First of all, I've got to get this wiring sorted out in my head, given the crappy schematics JLG made for this one. I need some help as to which wire is going where. I'd like to make the madness a little more simple by focusing on one thing at a time, other issues will follow. For now, let's forget about high engine while driving and focus on mid range engine speed.
It looks like the red wire on mid range board is going to terminal 14 on terminal strip, that would be one of the ingition terminals. Black wire is going to terminal 18, that is ground terminal. The one I can't tell for sure where it goes is the white wire, looks like it goes to 87A on high engine relay, is that correct? Also, would there be a yellow wire connected to terminal 87 on high engine relay?
The wiring at the Precision Governor and actuator is really vague. Could you confirm the wiring at these components:
Precision Governor terminal 1, yellow wire, to terminal 4 of engine compartment terminal strip
PG term 2, brown, to term1 of strip
PG 3, orn/blk, 13 strip
PG 4, wht/orn, 5 strip
PG 5, wht, 14 strip
throttle actuator:
yellow wire to 4 of terminal strip
wht/grn to 6 of strip
May have more questions, but I'm starting with these.
today, light rain and drizzle , your theory about the sprinkler is starting to look like the only good solution.
There's the variation i've been looking for. Didn't notice it, this may be my problem. I'll check it out again , I have so many numbers running through my head I can't think straight/wait a minute...you said in post #25 that terminal 5 had 6.94V, not battery voltage.
Term 3 is connected to the neg side of the coil (tach lead).
I put a 12v jumper on term 3 when it wasn't working and would only get a blip in the throttle not a continuous high speed running of the engine.
I'm beginning to think I'm having a problem in the E-201 , with the speed working so randomly. Where would I be losing the signal voltage and what function causes the engine to rev up when the footswitch is depressed. Earlier you mentioned that the footswitch controls the proportional dump valve. What is the purpose of the dump valve?
My son is getting married this weekend , so I won't be able to play with the lift until Sunday. mark
Hey, if nothing else, screw in the idle adjust screw on the carbureator to give you a acceptable engine speed, take the E-201 off and have it repaired. It would only be gone a matter of days.
