im new here and to sears tractors, just acquired a super 12 my question is the switch will not kill the engine, am I right that the switch is supposed to be grounded when it goes back to stop and grounds out the engine?  if I remember right the switch has a power in from battery, a power out to voltage regulator, a wire to the cigarette lighter and cant remember maybe one to amp meter then black wire that goes down towards the engine.   There is also a wire that comes off the very base of the voltage regulator that has loop on it, this wire and the black wire from the switch are presently loose.  So im waiting to confirm what I should do with them.   I realize I also could have a bad switch?  thanks for any help. Matt.

I posted an answer in your other thread for the diagram.

Anytime you are doing electrical to your vintage or antique garden tractor never assume the color coding is correct. Many of these machine have been rewired at some point do to electrical issues or even mice and rats. Often we will see that they use what ever color wire is available so its best to check routing not wire color.

Download the manuals from our Manuals Section. Be very careful when playing with the wiring on those old Tecumseh engines with electronic ignition. It is real easy to damage them and the parts are very expensive. Post clear pics of your problem areas so that we can see what you are talking about. Good Luck, Rick

I can't agree more with that statement....That goes with anything electronic these days. Make sure the battery is disconnected and verify your wiring and connections before connecting the battery , verify it twice if your not 100% sure.

Thanks for the help do you guys know if the voltage regulator on a 68 or 69 super 12 has a wire coming out of it on the bottom that goes to ground?

[ptzbrg]

Actually on the diagram it looks like that ground off of voltage regulator goes to the bolt on starter mount to me

Okay I got that and can anybody tell me where that M terminal wire called the shorting wire where do I land that one at?

[ptzbrg]

I don't know what that dotted diagram is of that shows where the shorting where it goes

And one more thing a brown wire by the Shroud at the front side of the tractor it's a brown wire that disappears going through the shroud where would that one probably go? It's probably heading in life through the flywheel area.

Someone said to ground out the Magneto is that same as coil and is there a certain spot where you would attach that M wire to the Magneto just underneath mount bolt?
