Hello, I have a mf gc2300. Recently while using the tractor I shut it off and it would not restart. The 40A slow blow fuse to the starter was blown. I could not find a short in the wiring on either side of the 40A fuse with a continuity tester. I checked all of the wiring visually on the tractor looking for a short or bare wire. I replaced the fuse and used the tractor all day with no problem, on and off the seat but never shutting the tractor off. When I parked the tractor I shut it off and did a restart with no problem but i noticed that the fuel gauge was quickly going to zero and the lights no longer worked, then the tractor would not shut off.
I shut the tractor off with the plunger switch on the fuel pump and found the 40A fuse blown again. Again I could not find a short with a meter. I then removed the ignition switch and found the back with the wires completely corroded. I have read most of the posts on this site and understand that the ignition is a common problem. I am leaning toward the switch shorting causing the fuse to blow as it happens during a starting operation.
The question is, Has anyone had luck cleaning the wire corrosion and reusing the switch or is the problem internal to the switch? I am trying to avoid buying a new switch.
Also, I think that I have determined that the wiring diagram is inside the repair manual and not in the operator's manual. Can anyone confirm that the wiring diagram is in the repair manual and if so, is the diagram readable? The diagrams that i have found on the internet are unreadable when i zoom them enough to be able to follow the wiring. It looks like the diagram may have a box at the switch location showing what connections should happen at each switch position.
Any help appreciated,
thanks
