John Deere Hydraulic electric problems 9750

This could help. On CaseIH machines these functions are on individual relays which are energized by another relay which is energized by an oil pressure switch on the engine. When I had this similar problem it was sporadic. To make sure I fixed the problem with one shot I replaced both the sending unit and the main relay. Was told this setup was for safety so you couldn't drop the header, reel, etc. by just turning the key on and not have the engine running.

That you can cure it by restarting the engine and that way rebooting all computers, tells me that you need a new armrest board. We've had to change one too last year.

Might also have the board in the armrest checked out, these have been known to flake out and cause similar problems to what you are having.

Thanks and right on. Bad board under arm rest. Mechanic said Deere told them they knew there was a problem and they have changed suppliers. Deere however, did not volunteer that information to owners or agree to replace the faulty boards. Mechanic replaced 3 yesterday and at least 12 over the past week.

It could still be the board again. Semiconductors are touchy, espcecially when engineered sloppy.
