Shut off solenoid

[crofutt]

Hello,
I posted this on the RK forum but no one has an answer. Since they are made by TYM I was hoping someone here would know.

I have a 1-1/2 yo RK 25 that won't start. The shut off solenoid, when the key is on should retract. I replaced the solenoid thinking it was bad but the new one is the same way. If I push the plunger in, it stays in until turned off then it won't retract. I've been removing the solenoid, turning on the key, push the plunger in then reinstall the solenoid. I can run the tractor until shut off, then won't start.
RK doesn't supply a wiring diagram even to their mechanics at their stores. If I had one maybe I could figure something out. There are 3 wires going to the solenoid, 12 volts when the key is on one wire, other two have no voltage (assuming one is the negative). But that 3rd wire may be something to troubleshoot but... No diagram...
Anyone else had this problem or have a suggestion what to try next? Or knows how to get a wiring diagram.
Thanks
Bill

Go back to other forum.

trace the wiring from he solenoid back. It probably isn’t actually energizing.

And, try finding a manual for a TYM from he same ime period, with he same size engine. And see how close he wiring is. (Sometimes my keyboard messes up and doesn’t recognize that I pressed the T-key. Sorry about the missing ones above.)
