So I removed an Ignitor II ignition module and Flamethrower II coil from a running 383 and installed it in my 440 Charger. It fired on a few cylinders, then no spark.

I should add that it ran a few months ago with a factory electronic ignition, then a no spark condition appeared. The starter is on a separate switch also. I removed the ballast resistor when I put in the Pertronix. The module mounting plate is well grounded.

1. There is 11.8 volts at the coil + with the key on. When cranking, it goes to -0.14 volts. It should be at least 8 volts when cranking. Why would this happen?

2. When I run a wire from the battery + to the red wire from the Ignitor, I still get no spark. Does this mean the module is junk?

TIA
