Frustrated - Need Expertise From Other Members
 

I apologize for this post not being about a Cub Cadet, but I have a question I need an answer to. Unit is a Craftsman/Sears (manufactured by Murray) RER with 11 hp Tecumseh. Machine will not start. Removed ground wire from ignition module/coil and will start, must ground to stop engine. With ground wire hooked up, machine will not start nor run.

Am I correct that his means the ignition coil is "good?" And issue is somewhere else in the tractor wiring? Or is my thinking backwards?

Just needing to ensure I am barking up the right tree.

Thanks!

Every time I look at this this machine for my F.I.L. I simply want to :bash2:

Yes. Sounds like kill circuit is grounding which is how they shut off. Possibly a safety switch doing this, you'll have to back track to see where ground is coming from. You didn't by any chance unplug the seat switch did you? They have a spring loaded internal jumper in the plug that will prevent someone from doing that and ground out. Not a hard circuit to trace but a schematic for it would e helpful

My best guess would be that Alvy is absolutely correct.

Often times the "grounding systems" (which are used to kill the engine) on these machines aren't of the highest quality.

I've seen a number of problems in this area, it could be something simple like a twig that got caught on the little flap and is keeping the coil grounded.

Got it fixed, it was the seat switch. Did not run with seat switched plugged in. Did not run with seat switch unplugged. Placed a plastic sliver of milk carton between the compression prongs (to "un-ground" them) at the seat switch plug, tractor end, and she took right off like she had been waiting for that for years.

This is the most interesting looking electrical plug I have ever seen to say the least. Took me a while to figure out how the crazy thing worked.

Thank you all for your help.

Good job, glad we could help
