My guess would be the ignition switch.Maybe some smart people might have an answer. I have an JD X48 this intermittent starting problem. These are the repairs I have done to solve the problem
Started working to correct a no start problem 2 years ago.
Replaced gauge cluster ( old one dead)
Cleaned all electrical block connections and secured wires.
Cleaned fuse block.
Replaced both battery cables
Installed new Battery.
All connections clean and well grounded.
Quite often now when I try to start it acts like the battery is drained, on occasion some clicking occurs. (Battery is fully charged)
When I turn the key on the dash does light up as it should.
On the start of a new day I would often need to click off and on the ignition key (multiple) times before the engine comes to life
Occasionally it fires right up.
When it has been used and is warm it quite often starts right up.
My thought is should I replace the switch on the brake pedal that is depressed during startup.
Could the ignition key switch need to be replaced.
