Ignition Demon 74 Slant 6
Hello everyone. I have been dealing with an ignition demon on my car and I have not been able to get spark. I have tried pretty much everything I can think of so now I am looking for some help. My car is a Canadian model 74 dart sport with a slant 6 and 904. I have rebuilt the engine and am now in the process of getting everything back together. What I started with was the stock ignition. I had a new 4 pin module, 4 pin ballast, new electronic distributor, ign relay, coil, plug wires, and plugs. I had everything hooked up as stock diagrams show and when I cranked the engine over I was getting no spark and the starter would very quickly die out like it drained the battery instantly. The battery mind you was also only 1 year old and hardly used. I ended up putting in a new starter (the mini one for a later model dakota) thinking that was the issue with it killing the battery so fast. Also, following a guide found here Replacing electronic ignition completely in 1970s-1980s Chrysler, Dodge, and Plymouth cars and trucks I upgraded my ignition system to use a HEI module from a chev vehicle. With that I also upgraded my coil to a flamethrower 3.0ohm model. Once I got this all installed when turning it over I still have the exact same problem as before, no spark, and the engine turns over for about 4 seconds and then it seems like the battery is dead. After this point I still have 12 volts at the battery and after a load test the battery is fine. I have also tried other batteries and it gave me the same result. As for spark, I have included a rough wiring diagram for how the hei module was installed and pictures of the wiring on the car aswell. I used a multimeter to check voltage and I am getting: (Run position: 12v at "B" of the Hei, 12v at "C" of the hei, 12v at both + and - sides of the coil, and the wires running to the electronic dist. both read 1.3v) (While Cranking: 8.5v at "B" of the hei, 8.5v at "C" of the Hei, 8.5v at both the + and - sides of the coil, and the dist wires still have 1.3v)
I have tried using the stock coil, a different cap and rotor, different plug wires, alternate batteries, and I still get the same results. I do know that the hei module is grounded aswell. The only thing in the ignition system that isnt new is the starter switch in the coloumn, but I assumed since there is 12v of power to all the right places in the car when it is in the run position and then the starter cranks over in start position that it is working correctly. Have I missed something in my wiring? Originally I thought there must have been an issue in the wiring of the stock igniton system which is why I upgraded to the HEI. Any help or thoughts is greatly appreciated.
