HEI Upgrade but No Spark (kinda)

You have to be specific. If you are referring to post 38, that diagram is effed up I can't see what they are doing. I will say this about coils. It's been awhile, and I no longer have the coil in question. There are "some coils" not wired as you'd expect. They have 4 terminals, and seems to me?? if I remember, that two terminals close together are NOT connected to each other at the coil, but rather are each end of the coil, and same on the other side. You have to CAREFULLY use a meter and carefully determine which two are "zero" ohms and which are actually across the coil primary winding.
