PCM Repair/ Charging Problem?

Recently had voltage drop on my '04 6.0. Replaced alternator and all wires/fusible links from alternator to batteries and alternator to instrument cluster harness and fuses in the cab. This did not solve my voltage problem. Tested voltage output multiple times to make sure glow plug module wasnt still on(even unplugged it).

I believe the circuit from the alternator to the PCM and back to be the issue. voltages on the 3 pin connector on top of the alternator were 12-0-9 KOER.

I have heard that the PCM can go bad on just the circuit that allows the signal back to the alternator telling it to charge (Accurate?). Truck starts and runs fine, just won't charge.

Does anybody know of anybody that rebuilds PCMs or sells aftermarket PCMs?
