No spark but 1 spark on "shutdown"

you have the correct coil...put a volt meter on the + side of coil and see if you are getting 12 volts...i see your ballast resistor is wire....but do those wires go to the coil?.....there should be no resistor in the circuit...if you do not have 12 volts at coil...connect the two wires on the ballast resistor ....then check coil again...

the ballast resistor is dropping the voltage to the coil for the mopar system....you dont want that with that distributor and coil

Thanks a lot for your help,, very appreciated from all of you guys.

Reversed power to module will fail it for sure. When it failed, most often shorted so coil powered when ignition on. Spark will happen when ignition off. Coil may survive if not powered for long, but more than a minute or two the internal winding insulation will be burned. Working modules limit current, failed modules do not, so current is about 20A.
