Hello, I have the 1942 -47 12v pertronix ignition module in my crab distributor and the 1.5 ohm internal resistor coil. It has way too much spark for ignition components to cope with.

I tried fitting another 1.5 ohm ballast to the positive lead to the coil but this caused no spark.

I have another 1.5 ohm coil but if i run that I need the resistor witch will then cause no spark as it drops the voltage down to the module too low.

If I run the positive lead from the distrubtor module upstream from the external ballast resistor would that cause trouble? It then would be inbtween 3 ohms.

Having trouble finding a coil to match
