I found the problem by reading the BCM codes indicating high voltage, and my service manual indicated that the codes meant a problem with the charging system. Battery voltage on my Aeroforce gauge was bouncing all over and going as high as 15.5 volts.
After getting 2 damage alternators from GM I finally got a good one and installed it. The packaging they put it in is totally inadequate. Working great now.

I figured it would be either the battery or alternator. The battery is the main culprit a majority of the time. Glad you got it figured out.
These alternators, I believe, are on a charge as needed system or whatever you want to call it. Where is it isn't needed then the current drops and when is needed it jumps up. Anywhere from 11 to 18 volts.
It's crazy how things are with shipping these days. Only in the past 2 years have I started to get broken items or incorrect items. Just document everything when you open it and call right away to get it taken care of.
