What do you need
H although I don't have a wiring diagram I should be able to help you,Please wait to rate until we get it corrected and your tractor is up and running,[we only get paid once a month anyway].I will start off explaining your system,from the key start switch,or button,when you turn key to on position it power ups your starter relay,[you only have one relay] ,next from the relay it goes to starter solenoid,the small single wire on your starter,the starter relay has a couple function the main function is it allows a smaller wire size to be used to save builder money and so you don't have bigger wires every were,the other function is safety related it allows the system ground to be interrupted if it does not meet the following criteria,The tractor thinks it is in gear,and the clutch pedal is depressed,[note:early modals did not have clutch switches only neutral safety switch,so if it is in gear it won't start and run someone over.That is how your system is wired up.Now do you have a test light or volt meter so we can diagnose you system let me know which one you have and would like to use so I can explain how to check for a no start condition.The first thing you want to do is check the small wire going to starter solenoid for power while trying to crank over engine let me know and we will go from there.One last thing I understand you are frustrated with our service, you did not get the attention you deserve or expected I understand and I am happy to help you, please rate me by my answers not there issues thanks spanky
The wire from the stater seliond to the relay is working ,you can start it if put power to it ,but there is no power normal power ,what has me stumps me is
I understand .I will explain how a relay works that should help you give me a little while I just woke up ok I'll be back. but for now you need to check and see if from the key switch or start button with a test light put clamp on good ground then check all pins on switch see which one has power with key to on position Then check all pins to see which one has power in start position if the test light does not show a additional power to a different pin then switch is bad if it does then that is your starter start wire it goes through the neutral safety switch and then to the relay the relay already has a power and ground[at least it should have]and the coil side off relay has a ground from a another relay or switch and then gets power from key to go to power side off coil that completes the circuit and energies relay and the last pin on relay becomes hot and starts the tractor.
I worked on all types semis,forklifts,farm,fire,ect.
