I ran across a posting on another board. The author said that when dodge went from a points ignition to an electronic one, they kept the same coil. He said that the coil only produces about 12,000 volts and this isn't enough when the engine is running with a wide open throttle under load. He suggested that you wire a single ballast resister in parallel to the compensating side of the double ballast resister. He said that this would double the output of the coil to 24,000 volts and give much better performance when running under load. Is the coil output on these engines too weak? What's your opinion on his idea? Are there any other options for improving ignition performance? I have a '72 Dodge Winnebago with a 413, 4 barrel carb. I do a lot of mountain driving at high elevations with steep grades.
Ahh the 72 winnie theyr'e so ugly they are beautiful. I had a 72 Chieftian 27 with points. A mopar nut friend of mine had an electronic ignition set up for a 413, I did install a high output coil, splitfire plugs(expensive but well worth it)and heavyduty wires from a chevy 454, made a big difference. Also bit the bullet and ran premium fuel with lead additive. A good free flowing exhaust system will also help get the ponies up

You read correctly. You can install the parallel resister to boost secondary voltage output without any harm to your system.
