I'm leaning towards thinking it is my module.. it was my original hunch. I 'm not using the yellow wire. I bit the bullet and installed an MH engine harness for HEI and did away with it.
here's what I don't get- when it runs, it runs perfect... not a miss from idle to WOT. I thought maybe a faulty module would give a little degradation in performance or at least give me a warning hic-up or something.
Does anyone know how to put a meter on the module? I'd rather check it than hang a part.. I already bought a coil I don't think I really needed.
My next step is to make absolutely sure it's not a ground-issue. I'll strap the engine to the chassis really good and check. If that doesn't work, I'll alligator clip a ground from the ground clip on the distributor and put it to the frame to check.
If ground checks out, I guess I'll an el cheapo module from O'Reily for testing. They have a $17 job that will work as a tester. I just don;t want to shell out $90 for an MSD module if it is something else. All this makes me wish I was a mechanic, and not a parts-hanger.
