John Deere 110 tractor engine won't shut off

Posted by chuckby z5NY (My Page) on

I just fixed the PTO problem that I had and now when I turn the key off the engine continues to run. I removed the battery and checked the wiring connected to the ignition switch and everything seems to be tight. When I had the PTO problem (not turning on)and checked the wiring I didn't pull on any wires to cause a problem. I don't have a clue as to why it won't shut off. I would appreciate your help, thank you in advance.

That could have a couple different ignition systems according to the Kohler service manual.

If it's a battery/points system, 12V is not being shut off at the coil. That would indicate a bad ignition switch or the coil wire shorted to a 12 Volt supply, such as a charging system wire etc.

The other type uses a kill wire.
That is grounded to kill spark.

Using the wrong procedure to trouble shoot can result in fried parts/melted wires.

It's a Briggs & Stratton motor. How do I fix it to shut off at the coil or figure out if the coil wire is shorted out. Thank you for your time and help.

Are you sure it's a 110 and NOT an L110 or LT110?
I guess it doesn't matter, since all 3 supposedly came with Kohlers???

What's the Briggs-
MODEL TYPE CODE

Maybe we can figure it out from the Briggs parts manual.
Some OLD Briggs had battery/points ignition or those with a starter motor/generator.

We have to make sure we pick the right system or you'll see $ vaporize before your eyes.

I'm sorry, it's not a 110 the tractor is a 111 model 253707 with a Briggs & Stratton 11 HP motor. Sorry for the mistake.

There should be a wire from the M terminal of the key switch to the magneto.
This wire is GROUNDED when the key is OFF to kill spark.

Either the wire is disconnected or the key switch is bad.

Hi, thank you. Is the ignition switch marked so I know which one is M or maybe any idea what color wire it may be that I could follow it. There are alot of wires coming out of that ignition switch. Thank you so much for your help. I can't thank you enough.

I simply don't have access to JD schematics.

The kill wire would go up under the engine shrould.
Of course, so do the alternator wire(s).

What I would suggest is remove the shroud.
(your cooling fins probably need to be cleaned anyway)
Physically observe which wire connects to the magneto "tab".
Trace that wire back to the key switch.
It will likely go through various safety switches, such as brake/clutch switch & PTO/attachment switch.

Somewhere along the line, you should find a bad connection.
It could also be a bad safety switch.
Usually, it seems they fail in the opposite manner though...

THANK YOU THANK YOU I started tracing wires and found the broken wire. I fixed it, started the tractor, then turned on the PTO, shut the PTO off and then turned the key off and the the tractor stopped running. Oh, it was really nice of you to help me out. I really appreciate your help. Thanks again. Have a great day.

Great!
We always appreciate feedback.
So often, the OP never gets back, so we don't know if our suggestions worked or not.
It helps educate us too, when we see some kind of "trend" in specific problems in certain brands of tractors or engines.
