2240 is dead as a doornail

You're correct ign switch in the on(run) position should no affect temp of solenoid unless ign switch was shorted internally. Check for voltage when ign switch is "turned on" at wire on starter solenoid that attaches to ''S" terminal. With someone sitting in seat with clutch pedal depressed try shorting across from top post to "S" post on solenoid to see if starter will engage. On some models JD added a starter relay to provide more volts to wire that attaches to "S" terminal.1st photo is a kit but just the relay(2nd photo) is about $25

With tractor in neutral, I am getting 10.5v at the S terminal as well as the copper link to the starter. If I hold the lead on the S terminal, voltage starts to slowly increase to 10.51, 10.52, 10.53 etc. is this normal? I didn't have anyone to help me hold in clutch today but I tried jumping solenoid with screwdriver and got some sparks but nothing else. I may try replacing the relay. It's pretty rusted and one wire has some pretty noticeable corrosion.

Are you getting voltage at "S" terminal with inj switch in off, run or start position? Climbing voltage indicates poor connection.

Put a large socket on the front crank bolt and see if you can rotate the engine forward or backwards. The starter itself could also be bad, not the solenoid. You could also after determining the engine rotates freely, use a jumper wire and jump the starter to see if the vehicle will spin over. WARNING - WARNING if you decide to try a jump start triple check to insure the tractor is in neutral and the brakes are set. Also do not let small children play tractor driving from the seat while you are trying to do a jump start at the starter solenoid.

Good advice from Gator 6, It sounds like your starter is stuck ,

Tx Jim, I haven't checked it with the switch in the Start position. Maybe I need to? Where I am getting my voltage readings is at the S terminal with ign switch in the RUN position. With switch OFF I get 0v, when switch is in RUN I get 10.5v. Thats with the battery testing 12.6-12.7v. The copper link from the solenoid to the starter also tests the exact same voltage as the S terminal. Thanks for all your help!

Thanks Gator, that is something I have not tried yet. May not get a chance today but will try that tomorrow. I am not too worried about the engine as it was running fine and then weather turned cold and she would crank just not start and then after a couple different times trying to start she was just completely dead.

The starter is well hidden behind the loader and will be a PITA to take off so I was hoping it was not bad. :thumbdown: But its really starting to look like it.

With ign switch in run position one should have ZERO volts on starter solenoid "S" terminal on starter solenoid.

So that would explain why the solenoid is getting warm? Do you think I should try replacing the ign. switch?

I'm guessing it is probably a bad solenoid or the insulation around the solenoid post is bad. I would guess the insulation around the post is worn out. If your hot battery cable to the solenoid is able to make continuity to the housing you will end up with a direct short and it will make your cable hot as sin in not time flat.


I'm 99% sure whats happening is your pos. cable is grounding at the solenoid stud. A lot of times the only insulation between the stud and the housing is either epoxy, rubber or leather on older models.

Take your multimeter and go from the hot post to the housing of the solenoid and see if you have continuity. If your ohm meter beeps than you have continuity and you have a direct short going on. That scenario would definitely be cause for a hot wire and the starter not working since electricity goes the path of least resistance.
