Okey, I have one question.
How did you split the CD module and how did you remove the insulation putty?
I think it is easy to repair the CD module if you manage to remove the putty.
The main components in the CD is the capacitors and the SRC transistors/thyristors and I think these two fail after avail.
The trigger voltage open the SRC and dump the stored capacitor voltage from the stator into the ignition coil.
CDI Electronics had a R&R system for the old Chrysler engines that was equiped with the MAG II system and they used some kind of solvevent to remove the putty.

I have never split one. My luck, if one went bad I could just swap them around and the spark would be back :)
They're set up so you can use the first side and then the second side.
But the second side won't work unless the first side is being used( hope you understood that)
The following link is to a place that sell them cheap, or used to???
92-5104 Blue pack. $71.
Other places have them as high as 800$

I was not successful at opening it clean. Dremel, chisel , multitool.. it came out in pieces........ broken pieces.... i was able to identify the capacitors..... around 3/4" in diameter x 1 1/2? in size. As far as i know it is nearly impossible to remove the ........epoxy? or whatever they use........ the black hard/brittle filler.
