I'd also check the wires and connections for continuity...it maybe that one of those wires had a inline fuse and it blew, or has some internal corrosion.
Also check all your fuses and relays

Considering that the Alternator charges/works in a different truck. Suggests that its more of a wire or connection issue. I presume you checked for bad fuses ...there might be a "mega fuse" that got tripped. Sometimes they go when re-installing battery or alternators.

Is the 12v on the large gauge charging cable or a smaller wire in a connector?
I'm looking at our 2003 wiring diagram which may be different, but there are two 12v lines.
On our 2003, there is a fusible link in the large gauge charging cable, Gray, from the battery that looks like a bulge in the harness and a 10A fuse, F1.9, on the Orange/Light blue wire, pin 3 - sense circuit, from the fuse panel to the alternator.
