66 barracuda ignition problem

Its cool alot of good theorys came up here, and i condsidered all of them. I was dead set on the fusible link, i even bought a new one. However, the actual failure (this time) was not listed in this post. As i mentioned the last "lost of power" was wiht the failed/burned out ammeter. when i repaired that i installed a single stud post http://images1.mcmaster.com/Contents/gfx/large/9365t5p1-d01bl.png?ver=14888902
stacked the three wires on it and dah-duh ammeter by-passed. it worked and i would have gotten away with it, but one of the ring lug for the supply power wire developed some invisible barrier that magically impeded the flow of electrons to the other two lugs. cut them off, cripped on new ones. interesting
