There might be a trans guy respond to clear any questions up. (That doesn't sound right) Some dampers are not to be used on certain motors. Hope this all helps. I'll get back if the electrical seems to be one of the problems. Just posting thought to see if something comes to light.
Just a little on electrical components. There is a 10% leeway ether way on the the operating voltage. If not within those parameter there are problems, over heating or just not working. Electronic have tighter tolerances.
You read and you understand how a coil fires. It fires only when the primary power is turned off and discharges through the secondary windings generating spark. The MSD unit is now controls that. But MSD Multi Spark Discharge. Up to or more then 400V and many times.

Orange + to coil?
Ground strap there should not make a problem. There a ground cable from the battery right.
Looking back you said: 3. I have 12v of switch power to the MSD 6a. Where did you check that?
