Well I (finally) figured it out. It turns out, I had the brown wire, and the number 1 wire hooked up backwards
. The brown wire was "black" from all the years of crud built up on it. Something I did not mention was I just rerouted all the wiring for the engine and placed it in conduit. I replaced all the connectors such as the alternator, distributor power wire, etc. So I must have wired it backwards even though I did it one at a time. So my wiring "improvements" ended up eating 3 alternators and a few days of my time but this is what happens when owning a old truck. At least I understand GM alternator wiring better and got to look at all my under dash wiring up close and surprisingly is in very good shape. Thanks for the help from everyone that replied!
