When you install a Pertronix or Compufire ignition module you loose the ability to statically time the engine. Can't be done.
If you didn't move the dizzy in the clamp, you should be right where you left off with the other motor (provided the distributor drive gear was set correctly on both motors). If you did move it, then do what Troy (Messix) said to do.
Do yourself a favor prior to installing the dizzy,
check out this page and perform the slight modification inside the dizzy to ensure your wires stay in one piece. The Pertronix units are notorious for this and I see this in 75% of cars equipped with them. The engineers should have made it so the wires were coming out of the other side of the module. . .
So you are saying that if you turn on the ignition and rotate the dist, you cannot get the pertronix to turn ON without the engine running?
Sorry but I have done it before.
The 12V test lamp turns on & off as you trun the dizzy.
Or are you saying that it just wont be accurate?
And when you switch from points to pertronix the "phasing" of the On/Off changes so the position of the dizzy needs to change between points & pertronix.
They trigger at slightly different points.
I have tested the magnetically triggered ones and the optical modules.
Both will turn on/off for rough static timing.
