are you triggering the CD with the test light?
thats strange that the CD gets quiet when you ground the points, i thought that is when the oscilator is doing it thing so the cap can recharge. i will have to look into that.

lets back up a second. use the diagram above above and recheck some stuff. there is not much needed to make this work. 12v, a switch (the points) and a voltage multiplier (the coil).

disconnect the CD. with the points closed, veryify ground at pin C and an open when the points open.
verify a short from pin A back to the CD unit,some resistance through coil, but still basically a short. these are done on the wire harness, not the CD itself.
if you need to break it down, pin A to pin 15 on coil, pin 1 back to CD unit.
verify again 12v on pin B with key on. from the pic above, i dont see how you are checking this, the connector should be in the left side of the engine bay, it looks like you are around the coil.

dumb question here, did you remember to put the rotor back on? my mind was wandering one day when i pulled the dizzy and i forgot the rotor.
