Thanks Dave...

but I still could use some direction. The ignition system on the car looks like a basically stock early seventies Ford. The builder didn't put in anything like an MSD.

If I follow the wires from the coil to anywhere but the distributor, I end up in one of two places: 1) a small square metal box that looks a lot like a narrower version of an old voltage regulator, or 2) a rectangular piece of porcelin. Neither of which have anything resembling a 'ground' wire.

What should I be looking for and how should it be grounded?

Thanks again,

Keith
