For original style Farmall swithches, there were two types. For magneto ignitions, the switch had a single pole on the bottom. From that pole a wire ran forward to a stud on the side of teh magneto. With the switch button in thee "up" "RUN" postion the switch was open. When pushed down to the "STOP" position the switch was closed, and stopped the motor by gounding the magneto. Ground was reached through the body of the switch being mounted to the chassis.
The otherwise identical (for outside appearance, anyway) switch for battery ignitions had two poles on the bottom. In that case the switch was closed in the up postion, allowing the juice to flow from the battery (one pole of the switch) to the ignition to the pole connnected to the igntion coil. Pushing the switch down opened the connection, breaking off power to the igntion to stop the motor.
If your switch has to poles on it, one should run to a battery source, the other should run to your ignition.
That's what I was thinking when I said it would be easier to wire a normally closed switch. I would use a boat kill switch, but it is too late now. I have NO idea how to wire a normally open.

Up till then, this tractor had been running a corn grinder and pulling a trailer. It had new unfilled rear tires and no wheel weights. The garden was already sprouting when we hooked up the mid-mount shovel cultivators to the Pony. The seed bed was soft enough that the rear end would spin and slowly work its way to the downhill side of the gardens slight incline. From this, we learned our lesson sinc
