Ballast Resistor By Pass Chrysler Valiant
Hello Australia @daniel9843
I believe I know what your problem is with your ignition conversion not idling correctly.
Sounds like you did a High Energy Ignition upgrade. Mopar HEI conversions we do here in the States. Chev HEI module that fastens under the mopar electronic distributors.
So I set a mopar HEI conversion up to test on my Engine Run Stand, like this with a standard coil, it did not idle correctly. In fact it would shut down below 800 rpm.
With the Ballast and without ballast same results.
Realized I needed the High Energy E-Core coil that runs cool on straight 12 volts with no ballast resistor that is designed to work with the High Energy Ignitions.
Same E-Core coil that comes with the 1985 to 1994 Ford F150 Pickups, can get one at your local Pick-and-Pull parts yard. Grab the 2 prong pigtail and 10" of wire with it, and grab the coil lead wire that goes to the distributor too cause it has a special latching end at the coil.
Rock Auto sells them too reasonably.
These coils are nice cause they have 2 spades and are clearly marked + and -. Simple to hook up like a regular coil.
Anyhow the E-Core Coil solved the no idle/poor idle problem 100% Running the mopar HEI conversion distributor.
Spark Plugs are even burning themselves cleaner now too, with the higher voltage 40,000 plus volts e-coil.
So Yeah, straight through wire your ballast for 12 volts, use the E-Core coil, and you are good to go.
Win Win !

3 Ford E-Core coils pictured here with handy 2 spade design. Don't need that inline condenser, that's for radio noise. But definitely grab the Factory Ford coil pigtail.
Upper right coil is Chev GM 3 round post design, less desirable.
Special Ford e-core coil lead.
Locks on Tight
Good Luck with your project.
