MSD 6a Cranking but no spark issue driving me crazy.....

Hi guys,
Hoping you can help......
I’ve just recently purchased the MSD 6a ignition system and wired it in as per specs in the manual. The car was driving fine prior to MSD 6a ignition when 12volt ignition wired directly to the +coil and distributor wired to the positive+ and negative_ of the coil.

I’ve run into some problems trying to get the MSD 6a ignition to spark. Here is some information.

• 1966 Ford Mustang 289
• Rewired with painless performance wiring harness
• After-market ‘bosch-style’ Distributor is an electronic distributor red and black wire (no amplifier)
• Coil is a Pertronix Flamethrower 2 (0.6ahm 12volts)

I’ve wired in the distributor as per the MSD 6a diagram for an aftermarket magnetic pickup distributor

I’ve completed the spark test by shorting the green and violet wires and confirmed spark.

There is no ballast resistor fitted to the car.

Using a voltage meter I can confirm 12volts at the small red wire going into the MSD 6a from the ignition switch in the ‘on’ position. At the ‘start’ position on my ignition switch the volts drops slightly as it cranks which I understand is normal.
I’m not getting any spark through the distributor. I can confirm the distributor is turning when I crank the engine.

I changed the magnetic pick-up in the distributor to a brand new one and confirmed it works.

I swapped out a the coil to a known working coil and still no spark.

I’m stuck as to why this is happening. Any ideas?

Thanks Olivethefet, appreciate the honesty. I guess I was drawn into the claims of improved idle and throttle response. I've had my head under the bonnet for the last few days and can't make any sense of it. I've been reading threads for days and it's really difficult to find an answer to this issue. Looks like i may be taking your sound advice.......
