What they are trying to do has been out forever (msd ignition comes to mind- 1978?).. but it is an informatve site with details.
I have an old school ignition.. I am remnded of crud on the battery, and no diode as a pssible reason, or prevention of back emf... I should read up on msd's version and install my own. I have played with resistors for ECU circuits with great success..but ignition is a scary thought to me.. I must get over it.
When I get to it, I will post the 3 dollar cure..maybe even from radio shack. (thier stuff is ever so tiny however)
I have ordered from the net.
