13.2 volts isn't enough. Are you reading this voltage with a scan tool, a hand held voltmeter or the gauge? Are you reading this voltage at the battery or at the back of the alternator? Are you reading this voltage with the engine idling or while reved up?
Are all the accessories off or on?

You should test the voltage again at the back of the alternator and if it's above 14.2 volts there, replace the wire/cable from the alternator to the battery.

Chevy Mechanic: Mike S., Chevy Mechanic replied 2 years ago
Actually it appears that wire/cable goes to a junction block before it leads back to the battery, so check the voltage at the back or the alternator and at the junction block. If the voltage is above 14.2 volts at the back of the alternator but also above 14.2 volts at the junction block, replace the wire from the junction block to the battery but if it's above 14.2 volts at the back of the alternator but that 13.4 or lower at the junction block replace the wire/cable from the alternator to that junction block.

Chevy Mechanic: Mike S., Chevy Mechanic replied 2 years ago
So you had 13.4 volts at the back of the alternator?
If you are seeing 14.5 volts at times, it sounds as though this is an intermittent problem and I would check teh voltagees feeding the alternator.

Here is the wiring diagram.

Chevy Mechanic: Mike S., Chevy Mechanic replied 2 years ago
I just read that this has the Electrical Power Management system. I assume that is what you were talking about when you mentioned some sensor on the battery negative cable.
While running, the battery degree of discharge is primarily determined by a battery current sensor.
The generator battery control module is a serviceable component that is connected to the negative battery cable at the battery. It directly controls the generator field control circuit, charge indicator control, input to the generator.
If the generator battery control module loses communication with the PCM, the default voltage will be set to 13.8 volts and the module will set U1016. If the generator battery control module loses communication with the body control module (BCM), the module will set U1064.
So, with that done said, using a scan tool see either of those 2 codes or any codes for that matter are stored in the computer modules.

Codes B1487, B1390, B1488, B1492, or B1516 may also be set.

I would just replace the battery current sensor and try that. I see it listed for like $25.
