Here's an Idea Omar. And just an idea. Did this years ago in High school on a Nova I had that everyone wanted to sit on at hang-ins to pick up chicks.
Wire the output of a HEI coil to the chassis. The tires will insulate it and keep it charged, and mount a rubber isolated switch under a fender or somewhere only you know where it is to unload it harmlessly to chassis ground. It could even be wired to the door locks on modern cars as long as you use a rubber insulated key, I suppose.
Anyway, anyone touched the car, on the ground, WAMMO, 60+ K-volts.
It's a motivator, that's for sure! It did work. Now to challenge my lil brain on exactly how I wired it. Back then I was into electronics techie stuff.............The old Radio Shack days,
