Greetings . . .

Unfortunately, there is another piece to the puzzle beyond the switch. There is a gizmo called a Rev-Pol transformer. As I understand it, this special transformer is wired between the switch and dizzy. The switch is used to change from street tune to strip tune by reversing polarity in the transformer.

I have yet to find a good tech article on these to get an understanding of the electrical properties at play - specifically what these additional windings in the Rev-Pol transformer do to improve spark at high RPM.

Here's a somewhat blurry scan of magazine ad:


These are dual coil dizzies - so you should find only 3 cam lobes on the shaft.

I would imagine that the dizzy could probably be wired without the transformer or the switch. You might try posting a question on the Mallory tech site.
