I lost all my functions with my cab controls. The machine will not crank with the key but i can jump the starter with a screwdriver. I cleaned the ground wires at the back. I was wondering about maybe a ground on my cab.

Any luck yet. Do the headlights and radio work or cab blower. Check breakers and relays in engine compartment.

The JD tech has been at my farm for the last 3 days. Today he put in a new circuit board in the console that runs everything. It started up with the key and everything works except my engine RPM speed. It will not speed up. He has cleaned every ground cable on the machine. PLEASE HELP I am at 24 hrs shop time as of today
