If the Thunderbird's ignition system is like the Mustang's, it runs on 8 volts. I only installed it because we were having a random stalling problem that I couldn't solve (ended up being the starter solenoid) and changing to the electronic ignition was one variable to eliminate. We added a Pertronix to my wife's 1966 Mustang GT and it does fire noticeably faster. More power can cover for things like bad grounds and a gap that's too large, but in general, putting a more "powerful" ignition system on a car does exactly nothing in terms of combustion.Īn electronic ignition can, however, help the engine fire faster. Spark is spark and it will only be enough to bridge the spark plug gap. So in that regard, an electronic ignition does not make a better or hotter or more efficient spark. Even if you have an ignition system that can make 1 million volts, you'll still only use enough voltage to make the spark. Ohm's Law (V=IR) says the voltage at the spark plug will be exactly equal to the amount of energy required to jump the gap, no more, no less. As you might tell, I am below amateur when it come to electrical issues.
If I can hook it up just as the stock, that would be perfect. Just thought there could be a benefit to the hotter coil. I called tech support at Pertronix, they are closed until Monday. I felt if I by-pass the resistor, that would negatively impact the those hook-ups as it think it would cut off power to those two wires. One goes to the carburetor, the other looks like it goes to an electric fan that has been installed on the front of the radiator. So, can I just leave the wiring set up as is, and attach the Flame Thrower coil exactly as the current one? The reason I thought this might be necessary is there are two wires leading from the top connector on the resister (I assume power out). The coil is 1.5 ohm, and I think that is what the resister is too. Anyway, the instructions for the 1281 and Flame Thrower contradict each other. However, maybe that's not really so, as the car is running. The threads, and parts suppliers, led me to believe that the "hotter" coil was needed. Learned one lesson-Received new stuff, removed distributor cap.There is a Pertronix 1281!! However, it is hooked up to a stock coil, which is hooked up to the resister right next to it. After reading threads about the Pertronix 1281, and decided to buy one and mate it up with a Flame Thrower coil.
