Cdog welcome to YT. Although the term ..ground.. is a true and proper description of the action of a magneto kill switch in this case it leads to confusion. In more technical terms the kill switch is completing a circuit. The kill wire connects to the contact point circuit in the magneto. When you push in the button the contacts in the switch make a contact back to the chassis. The base of the points contact set that does no move is connected to the magneto housing, which connects to the engine and chassis. The kill wire connects to the moving part of the contacts of the points ..the breaker arm.. that opens and closes the primary circuit. When you push the button in the breaking part of the circuit becomes solidly connected or is ..closed.. to the chassis through the kill wire, this disables the function of the breaker points and ignition spark is stopped. As was said, this function has no connection to the battery or its polarity. Hopefully, that is not a failed explanation. Would probably be more clear with some diagrams.

Amana Colonies served as a respite where we ate a family style lunch that sustained us with more food than could reasonably fit into our ample physiques. The show at Ankeny
