On the battery side of the starter relay should be some smaller wires going into the main harness. They should have small tags on them saying "Fusible Link". Each link is about 12" long and then goes to regular wire. The fusible part is a smaller gage wire that acts as a fuse for redundant safety along with the fuses in the dash.
Aften yanking all the unwanted emissions crap out of mine, including all the wiring for the solenoids and variable venturi carb, I have only the one fusible link going to the main harness and it is red, I think. Another way to identify the fusilbe link is there is a larger rubber piece on the terminal end at the solenoid for that wire.

Oh well overall a good week for diagnostics on the electrionics, hopefully the fuses fixed the radio issue.
Couldn't do it without all the fantastic help from this site. You guys are truly awesome!

I really wasn't being sarcastic, although I'm not above that. 
I just hadn't seen nor heard of a fuse tester, and I thought I knew something about testers and electronics. Maybe "novel" wasn't the right word, but it was the first thing that came to mind.
Burnt out headlights? Two of them? That may go along with the alternator problems. I've purchased 3 trucks in the last year and none of them had a single headlight out. I'm knee-deep in used headlights that no one wants. Anyway, the point is that having two out points to having had something else happen, such as a serious spike in voltage, which might happen when an alternator fails. And, it may have something to do with so many dash lights being out. In fact, it might account for fusible links being fried.
But, you are getting there and the methodical approach is commendable. Good job!

I would suggest a new regulator as well. When my alternator went south I bought a new one, pulled the label off of it that said "You REALLY should put on a new regulator", and installed the alternator. Didn't help a bit. Ran the short-here-and-find-out-if-the-alternator-works test and it worked find. But, that test bypasses the regulator and puts full field on the alternator, which is exactly what the regulator should do when the battery is low like mine was.
Back to the parts store, buy a new regulator, and the problem was solved. Further reading tells me that it is common for a regulator to fail when an alternator does, and it sounds like your alternator went out in a big way. So, in your case I'd BET on a bad regulator.
But, if you are bucks-down then maybe buy it but don't put it on until you try the alternator. If all is well then take it back.
