I have the blaster coil and new plugs and MSD wires (the 8.5 red ones). I am going to try to install the capacitor as MSD recommended in line with the 10 guage wire and also experiment with an additional fuseable link with a 7 amp fuse so that while I am continuing to trace the system, I don't have to wait 3 weeks to get another box. I will also use the rubber mounts to eliminate vibration. Most of these components are either bad or good. I have no intermittant problems with the system, it works until it melts down and doesn't work again. Many of the posts I read do talk about intermittant problems i.e. the system works, and then restarts after it cools down.

Here is the way it is connected:

Heavy red to the hot side of the starter solenoid
Heavy black to the engine block
Thin red to the ignition relay box (ign coil) which lights the tester when the key is on. However when I unplug the line to the relay, I can still light the tester with the red wire from the control box as I believe that red wire is spliced into the line that used to carry the ign coil terminal to the ballast resitor. The ballast resistor is shown on page 9 of the MSD instructions as ok to have in the line to prevent voltage from leaking through the control box. I suppose that I can replace that too or bypass it on the next try. Anyone think the ballast resitor could be doing it?
