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.

Problem solved !

Roger, our are absolutely right.

The stop-wire was already connected to the ignition coil but ended next to the accelerator cable.

I just connected the yellow cable from the ignition lock (being grounded in position "off") to the end of the stop-wire.

Engine is perfectly stopped by turning key now.
Sorry thats my bad bad english again. My dictionary listed "roger" as a synonym for "right" or "understood".

I tried to response to Toms post with this directly.

Does that make any sense now? ;-)
"Gremlin" ;-) thats a perfect description.
Thanks guys.

I really like the mentality of this forum. ;-)

I took a picture some minutes ago to visualize the position of the stop wire.

The black stop-wird is attached to the ignition coil, goes "internally" through the engine and will end next to the accelerator cable.

I have connected a blue wire bridging the yellow wire being grounded in the "off" position of the ignition lock.

Best, Jolanda

PS: Don´t be confused. This engine is NOT the original JD 100 engine. Its a B&S 8hp engine built in 1995 now. The mount-point for the accelerator cable changed from vertical to horizontal.
