Crazy X585 starting problem

Hi there- new to this forum, but member of others and know all too well how helpful these places can be.
Here is the scenario:
I was completing basic service for an X585. Change oil and filter. Replace spark plugs. Service air cleaner.
Remove black screen side panels from the steering column console and blow out interior space with compressed air. Unfasten oil/transmission cooler from the engine radiator and clean it and the engine radiator with compressed air.
Re-attach the tranny cooler (now when I say reattach, I mean place it back up against the radiator and flip the little spring tabs back into the lock position-no hoses were disconnected for this process).
In the process of blowing out the radiators and the entire area inside the steering column console, I did have to jostle around the wiring harness a bit to access debris lodged towards the middle of the compartment.

Now, when I attempt to start the engine, the key switch engages the starter immediately when moved to the "run" position as opposed to merely priming the fuel pump and illuminating the instrument cluster.
Again, turn the key to "run" (not "start" position) and the starter engages immediately and stays engaged when the engine starts.

This is the most puzzling thing I have ever experienced. The answer has to be simple because I DIDN"T DO ANYTHING! (exasperation, not shouting)
I did check that all connections were intact, and as far as I can tell, they are. I did replace all 3 relays in the hope that one had gone bad from the ever-so-slight jostling they received when I was cleaning out the area.
BTW-if I pull the hot lead off the solenoid and turn the key to the run position, the usual normal stuff happens-lights illuminate and fuel pump primes. Of course then the unit won't start if I turn the key to the start position.

So, here I am looking to those with more experience to see if anyone has ever encountered a similar situation.
I am completely baffled again because I didn't so anything to warrant such a weird problem. It seems like I must have knocked something loose or grounded something out somehow, but for the life of me I can't see what it might be.
Any insight will be greatly appreciated.

Although I do not have a 585, I am almost certain the board was the answer.

Last year my JD wouldn't even crank, bought a book so I could trace the start circuit, found a semi-hidden board and blew it off w/ compressed air.

Tractor fired right up.

Good job!
