My first thought would be battery cables too. They corrode under the insulation and cause charging issues.
What is resistance from battery positive to the alternator post? A brand new wire, you should see ~0.2 Ohms. I highly doubt it's the PCM, and if you thought it was, I would invest in Forscan or some other type of scan tool to confirm the ECU is NOT commanding the alternator to charge.
