Test to see if voltage to solenoid is there when key goes to off position...

Thank you for your help. I can not seem to register/detect any power/current to the solenoid when I turn the ignition key to off. Do we know which fuse and which relay are involved? Thank you again.

ahswain,

I assume that your seat safety switch was working properly, turning off the engine with the key still on before you developed this problem of the tractor not shutting down by turning the key off?

Just a thought, have you traced the wires for the fuel shut off relay and the fuel shut off solenoid for any damage?

Here are a few pages from my 2009 MF GC2410 Shop Manual, don't know how much they will help with your tractor of a newer year and different model?

Wish you luck, KC

Another angle you might consider is to use a jumper wire from the Battery + to the solenoid, when the tractor is running. If it shuts off, the solenoid is working.
Expanding on this strategy, you might be able to follow power backwards, TOWARDS the shut off timer.
I would unhook the wire from the solenoid, then power up the disconnected wire, then try to follow it backwards.
