I'm sorry.  I forgot that I promised not to answer anything on this list
since you ALWAYS contradict me whenever I do.

There is a problem with that approach (which I suspect is exactly what John
has done).  The problem is that you don't know how much resistance is in
that circuit, and the Pertronix requires a low-resistance source of power.

In fact, the original coil wire will pass the above test.

So if you want to do it that way, use a relatively high power load (like an
old headlight bulb) to test the circuit, then check how much voltage you
get.  If you can get 12v with a headlight bulb lit from it, it's low enough
resistance to power the Pertronix.
