ignition problems

I have nothing more that I can ad to what is said above to help you, first like said above the coil has too much power going to it with the key on.
This is what the ballast resistor does reduce voltage to 5-8 volts except with the key in the start postion (battery voltage)

any dark blue is power with the key on for the most part, chrysler usually taps into the harness for the electronic ignition around the distributor area from factory (the voltage regulator dark blue)
