    What Pro Mag 44 ignition components are the highest failure items used in blown alcohol applications. Putting together list of new spare parts to purchase. Will probably have spare everything but would like the thoughts of those that have been doing this for a very long time.

    Points Box then Coil then crank trigger. The best thing to do is run a complete set then once you know it was all good then take it off and mark it and put it away and run the second set

    Thanks Mike. When you say complete set would you also include the mag too? I have seen where a mag came back from being checked with a clean bill of health only to find that it was not operating well enough.

    The mag is an expensive spare. If you can have one as a spare then that is good. It is probably the most reliable part of the system. I understand what you are talking about. Had a mag show a problem on the engine dyno and swaped it and the problem went away. Took that suspected mag to the MSD trailer at Indy and watched the guys test it and it showed 47 amos and a great waveform. The test showed it was good.

    Thanks for your input Mike. Will probably go ahead and purchase everything including the Mag for spares. Nothing worse than having a problem and replacing only what you have on hand. These things are too damn expensive to throw away runs or worse, wrecking stuff. Thanks again for your time!!!

    Here is my failed parts list:
    - points box (died with no warning)
    - Pickup in the base of the mag
    - The mag itself (it only fired one spark and nothing else)

    Have made it a must do for the off season to have the complete system tested.

    If you can swing it, get everything.

    It's one thing if the car just dies, or won't start. It's pretty elementary at that point - you change components until it fires up (theoretically).

    But when you start getting a miss, or the just isn't running as good as it should, at "X" cost per run, is it worth changing individual components until the problem is fixed? Some people have a higher tolerance for doing that than just changing everything to ensure the problem is eliminated. Depending on how many runs it takes to eliminate the problem, one may be more expensive than the other.

    The worst ignition problems come when it really starts acting up and can DESTROY an engine pretty quick.

    Being electronic components its harder to tell when a part is about to fail or out of spec.

    Thanks Will. I was really leaning toward your line of thinking before posting my question. Already ordering all of it to be prepared for the next season. Your input is appreciated!!!
