magneto question

hooking up the kill switch in our sprint car. does anyone have a wiring diagram for one ? the post on our internal mag where we hookit up does that show a grond when the wire to the kill switch is hooked up?
thanks Gene

I used to run mags from French Grimes. It's been since 1993 or so since I've run one on a drag car. So my mermory is a little fuzzy. The screw post on the side of the mag is grounded to turn off the mag. Is that what you're asking?
