Here is a challenge... I needed to replace the thermistor on my 4500 (the tractor was having fuel shutoff solenoid problems). On one schematic the thermistor is shown on the back of the fuse panel behind relay #3... it was not there. Then I found another schematic that shows a white and black wire to and from the thermistor. I checked the back of the relay and found these and the wires headed into the main harness. I cut and soldered in a new thermistor and the unit runs fine. I have searched the unit and cannot find the thermistor, I do not want to get into the main wire harness and the local JD mechanic has never changed one of these.
Does anyone out there know where the thermistor on the 4500 series is located as I would like to get the unit back to OEM specs.
