I have a JD 5325 that has been blowing a 20 amp fuse. I discovered the cold sensor switch was the cause. Still won't start. Does the fuel shutoff solenoid have a fuse?
After disconnecting the cold start advance at the injection pump and replacing the blown 20 amp fuse for the fuel shutoff solenoid, it should have started up. What volt meter did you get at the injection pump/fuel shutoff solenoid?
I have a 5325 and the repair manual on cd. The fuse blowing is one of the few problems I haven't had. Is this a straddle mount? 5 cylinder turbo? They have a control rod going to the unit injectors.
