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.

Jolanda, the wiring diagram for a 100 was discussed some time ago. Sorry I can't provide one but there are at least a couple members who were able to e-mail a copy to other members. Hope they see your post.

In the mean time, I believe the "G" position on the magneto equipped Briggs engine switch should show continuity to the switch base. So the base needs a good clean ground to the tractor frame and neg. battery terminal.

Memory is a bit fuzzy on this, but do you recall a Yellow, Black, or White wire that was connected to a spade on the magneto and going somewhere to the outside of the flywheel cover? That would be the one that needs to connect to the "G" part of the key switch to "ground " the mag. to stop the engine. It might be in a multiple wire plastic connector with the wires from the stator. The wire may have been attached directly to the points to do the same thing.

Hope you get the wiring diagram to save for the future.

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.

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.

 

[tommyhawk]

Yep, you missed it Mitchell. Roger had a post in there, but it is gone now.

Anyway, glad you have one more little gremlin out of the way, Jolanda.

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? ;-)

 

[jolanda]

"Gremlin" ;-) thats a perfect description.

 

[mcain]

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.

Don't worry, Jolanda. We don't keep score anyway. The object of the forum is to help each other even if we do get side tracked sometimes.

Maybe I'm just dreaming it, but I would have sworn Roger had posted a very accurate description of the yellow wire and where it probably should connect, just before I made post #2921. I attempted to just add a hint for finding the correct wire without a diagram.

Tom it wasn't me this time. Jolanda my heritage is 100% German with my grand parents on both sides coming here as children just before the turn of the century before this one. Late 1890s. To some degree I think in German language structure yet. Roger

If Roger posted a response earlier in this thread, I wold be interested to know what happen to it also.

 

[tommyhawk]

Well that settles it. I apologize for the mix up. I know I've had worse dreams than WFM content! LOL

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.
