Okay, so I put a 10g jumper between the starter and the alternator. I used 10g because it's what I had available. I had it tested this morning at O'Reily's and it passed...... 6 times. The odd thing is that the tester was reading 13.8 and my gauge was 12.5. My Dakota Digital gauge might also have an issue.
For some reason, I don't think this chapter is closed yet.

Did you find out the root cause of the problem? I'm also having an electrical issue with my LS3 swap. Sudden battery drain while driving on a hot day with AC full blast. Replaced the alternator and battery but still have the problem very randomly on hot days. I think it's a ground issue.
Thanks,
Ed
