Issue resolved...For now...
It turned out, that the plug that goes to the battery, etc...Had fried a wire in two..AGAIN....
UGH..
I predict a 3G swap in the future...
Now, it reads low voltage regulator, yet its charging @ 11-12v at idle...
It's running....For now

The pigtail was scorched...Had apparently burnt the wire up, down in the plug....
Same chit happened again, upon FURTHER troubleshooting, found a 10amp fuse had popped....
Replaced that, and re-crossed the cluster over as it was with the 1994 cluster in, and its charging....barely....12.35-12.89v at idle...
Tomorrow is gonna be me running a chitload of Continuity tests, and cleaning the grounds, checking the wires out....
Ugh....Bout to say F it, and simplt nab another harness off a donor truck I've found...

Btw...I peeled a tad of the shrink tubing back, and the actual fuselink is good.....The voltage seems about .30v higher, there, than at the battery its' self....

*Update*
I took the grounds loose today, cleaned them well, and coated them with Dielectric grease....
Cleaned the battery terminals, the exposed wire, etc...And coated those with Dielectric grease.....
Started the truck, and it appeared to charge for a bit, no change with throttle position though....
It started up and charged at ~13.75-13.60v....
Then, it drops and holds steady at 13.50v....Every so often, it'd flicker up to 13.52v.....
It held that for the 10 minutes I let it idle.....Ao I honestly, just don't know...Seems to be charging now, yet it has no affect, whether it's Idling, or revving....

Even if nothing it turned on, just to rev the engine? Just making sure...

The voltage regulator senses the load and adjusts the output. If there is no load the output will remain static. The VR not only increases output on demand, it also prevents overcharging.

You need to check to see that your ignition power wire to the alternator regulator is OK - if you don't have 12V to the regulator to power the field windings, you will not get any charge. Do a search on alternator here, many people have recently posted the wiring diagrams which show exactly what wire and what color it is.
I did a search and found this. I was wondering if the same applies to my '84?s

Yes, factory charging systems have been this way for decades, even going back to the days of generators.
