            I have read that the kick down on a 3 spd OD can cause problems with the Petronix ll  ignition.  That if you kick down it will burn out the system.  Has anyone had problems with this?

            Untrue. All my OD equipped vehicles run Pertronix ignition with absolutely no problems.

            Agree with Dobie. Been running Pertronix 2 with O.D. for 8 years with no problems.

            I have a 1957 Ford Distributor and a Pertronix I in my TBird.  I also have a Pertronix 1.5 ohm coil with no external resistor.  I experienced an intermittent miss that went away when I disconnected the O/D wire.  It did not blow the Pertronix Unit. The O/D kickdown switch is an open switch located in a place where corrosion, oil and grim can get to it.  The way I drive my car, I have no use for kick down.  Downshifting when I want to pass works for me. Since disconnecting the O/D wire, my car has been running for over a year with no issues.  If you blow the Pertronix unit, you are dead in the water.  You can carry an extra unit or reinstall your points. To me, having a working kick down circuit is not worth the risk that I will be sitting on the side of the road with a flash light and a screw driver.
  To be honest, I have never experienced a Pertronix unit failure and I have used a bunch of them over the years.  At the same time, I have experienced numerous failures of Chinese points and condensers.
