The Duraspark unit is not the most reliable spark box ever made, especially when located in the engine compartment. now, knowing that, i ground the plugs to the motor; look for spark and only hits after release the start button, and when it sparks it’s only once (not all cylinders at once of course). I left the resistor wire in place when I upgraded my 70 to Duraspark, and it runs great. The pink wire is a 1. It's 8-9 ohms, so by disconnecting the harness at the firewall under the hood, it would give you access to the terminal on that wire, then you go to the ignition switch connector, and do an ohm test for that wire. I tried several things to fix it with limited success, but eventually decided that maybe the stock ignition system could use some help. After installing the spark plugs, I started building the mount for the ignition computer, ballast resistor, and ignition coil. ?capacitor on the coil? Uni Moe wrote: I'm going to cut the pink resistor wire and install a ceramic style resistor ballast on the power wire to the coil. One of the misunderstood aspects of points ignition systems is that the ballast resistor (or resistor wire as used in most GM points-type ignitions) just limits voltage. We got lucky on this one. I always run a ballast resistor if stock ignition is being used, such as points, or the mopar ECM (orange box or whatever). Built a 347" stroker with a Duraspark ignition. An easy test would be to just drive around with the gas cap removed and see if the problem recurs. If you don't have a ballast resistor to the coil, that could make the module hot (depending on how the module is designed). As to the ignition I have on the car it is a MOPAR Electronic.

While voltage is reduced. 3+-+-+-BREAKER POINT IGNITIONSINGLE OR DUAL POINTS(USE THIS DIAGRAM FOR VOLTMASTER MARK II datasheet search, datasheets, Datasheet search site for Electronic Components and Semiconductors, integrated circuits, diodes and other semiconductors. You heard wrong. A reproduction of the original style 1955-1956 ballast resistor, Danchuk # 099 will work on any 1955-1956 classic Chevy. Ford's ballast resistance was built into the wiring harness (a resistance wire) rather having a distinct resistor block like for instance Mopars used. Problem one is, my truck doesn’t have a ballast resistor, but one voltage e-core coil. Chassis Numbers 01001-20627. All the wiring diagrams I've seen, including ones for upgrading to Duraspark and the Ford wiring diagrams for the 75-77 Broncos, all show a ballast resistor in series with the wire to the coil. (3) The ballast resistor included with the wiring harness is not used for a Duraspark I application. For anyone interested, the Napa ICR23 ballast resistor did just the trick for my duraspark/tfi conversion. Add to the mix that many aftermarket replacement modules of any grommet color have on-board dwell requiring no ballast for interchangeability, and it's. New ballast resistor. The electronic ignition pickup is located in your ignition distributor. Sometimes it will work fine, sometimes it will cause problems.
