I found the problem. Thanks for all your help!
The Black/Orange wire comes to the starter relay via the harness that comes from the headlight area. It has 3 wires in the wiring harness; 2 that go onto the same post with the battery cable, and 1 that is the push on red wire. The Black/Orange wire turns into a solid Orange 14AWG wire after the fuse link. The Orange wire had multiple spots that had aged really bad like Bobby said and broke into. I don't see how this didn't happen sooner. I could pull the copper apart. I trimmed the wire back to where there was some good Orange wire left and spliced onto it; it was about 3/8" from the fuseable link. I will retape it all up tomorrow. I have already taken off work, so that wont be a problem.
I can sort out other electrical items tomorrow as well. I am going to try to get rid of as much of the stock alternator wiring as possible; the more excess wiring that is there is just another chance for something else to happen!
