Cub Cadet 125 voltage regulator/solenoid

[golfgod7]

I just purchased a 68 cub cadet 125. The owner said the battery was dead so he jumped it directly to the starter and it fired right up. I purchased a new battery and turned the key with no result. I believe the problem is either the starter solenoid or voltage regulator. How can i properly diagnose these to determine where the issue is? I am also looking for a good source of Cub Cadet parts and manuals. Any ideas you may have is appreciated.

It sounds like the solenoid, safety switch or the key switch. Try this link for manuals Manuals
And here for the wiring diagram http://www.ihregistry.com/wire/C24.pdf

I think there is a black voltage regulator at the front near the grill, and vibrations take their toll on the wires going to it. The prior poster is correct about what to check, but I remember having to fix these wires on a 107 a couple of times. Just a thought. Good luck.

If you hear a clicking sound, then it is your starter solenoid.
A tractor will still run on a bad voltage regulator, but as the voltage is not being accurately regulated, it will burn your wiring harness.
