How to stop the engine ?!

Another stupid question from Germany ;-)

The pre owner of my JD 100 unconnected allot of wires and little pluggers. The safety switch for the PTO clutch is unmounted and short-circuited - but thats another story.

My problem is about stopping the engine. I think the regular process to stop the engine / ignition is done by turning the key to position "off". But my engine is still running in this position. I might found the problem by testing the wires coming from the ignition lock with my voltmeter. There is one unconnected yellow wire. My voltmeter indicates connectivity to the minus pol (ground) in key position "off". It has no connection to the minus pol in position "run" and "start".

I am assuming that this unplugged yellow wire is probably the right one to stop the ignition / engine. Right?

But were shall this cable be connected to?

Again, sorry for the stupid question but I don´t
have a wiring diagram for the JD 100.

Best from Germany,

I think your on the right track with the wire. Also some mowers ground out at the key switch I had that problem on a wheelhorse I restored cleaned paint off around the key switch and all was fine. And someone could have the wrong type switch installed.
Am I missing something I think it was Tom who helped you out I did not see where Roger chimed in. Or was his post removed? Glad to hear she is up and running.
Thanks Tom I can bet what was going on.

I was just trying to keep up with your problem good to know she is up and running Jolanda.
