    Bad HEI pickup coil

    A while back I was on the way home in Taco and about a half mile from my house she just crapped-out. No spark. Changed out the module, and still nothing. Had to be towed home. Just filled up with gas, too!
    I was quite crestfallen because I was so proud of my trick home made ignition with remote coil and module.
    But I kept my cool. I didn't freak. I just parked it and started driving another car for a couple of weeks. After some research, I did some testing and found the pickup coil to be open-circuit. Supposed to be 500-1000 Ohms.
    So I had to pull the distrib and completely disassemble it to remove the offending part. It is literally the heart of the distrib. Fortunately I had a couple of V8 HEIs sitting around so I robbed the coil from one of them.
    Worked like a dream! Back on the road!

    You seem to have a lot of HEI issues, do you think the heat from the turbo might be a contributing factor? Heat is a killer for electronics. I have run some of the scabbiest HEI units over the years and never had a failure.

    That's because yours have probably been genuine GM, not Chinese.

    That's partially true. There are people that swear by Skip White, not at him.

    I'm thinking that maybe since you have already moved the module out of the distributor, maybe move it completely out of the doghouse.

    Your issues remind me of the Lean Burn engine I had in a Cordoba. That thing would eat ignition controls twice a year, at $500 a pop back in 81. Chrysler mounted the entire ignition computer on the air cleaner, directly above the exhaust manifold. Later, they moved it behind the dash and those issues went away. Me- I just swapped in a standard electronic ignition.

    Designing industrial controls, we have to take heat into account. Sometimes we even need to install A/C in the electrical cabinet. Heat is already an issue in the early doghouse, adding a turbo surely increases the heat in there.

    Hope you get it sorted out, I'm battling an overheating problem in my plow truck right now.

    Cool

    When ever I replace internals in an HEI system I all ways go GM replacement parts.
    I do have to drive a bit to go to a parts store that sells these parts.
    The extra time and money is worth it to me.

    Now that I ran my mouth one will more of them might go down....LOL

    Good luck on your fix..
    Its a "van thing". A life style you have to live to understand!!!!

    It's at the old house, I'll dig it up and see if it will fit in a flat rate box.
