On the same belt. Its a cog pulley/belt. Tensioner is maxed out though. It doesn't seem to be slipping, but I didn't even think of that.

Sounds like an alternator going bad and I think you end up killing your brand new battery if that is the case. If you fully charge the battery, it should read about 12 volts with the vehicle off. If you start the car and test the battery and it doesn't increase to 13+ (and assuming you've ruled out all of the potential ground issues that can cause bad charging), then 99% of the time its the alternator.

These cars have an adaptive charging system like all modern gm's. The voltage varies depending on the state of the charge in the battery. It can be as low as 12v even when running.
In your case though it seems the alternator must be on it's way out.

So, I pulled the alternator and had it bench test. It passed a full load test with flying colors. I think I may need a new one anyways though. I noticed a chunk missing out of the base of the ground stud in the alternator. My best guess at this point is that it’s not making full contact, causing the intermittent issue of low voltage. I’ve attached a picture.. at least tried to. May have to copy and paste link.

Lol, Jeremy...Is that you being incognito with the alias?

It is possible, that's a sizeable chunk, and these cars are very sensitive to grounding issues. Personally, I wouldn't be happy with that alternator on my car. But that is a pricy purchase to make without being certain of the cause.

Lol. Nasty2SS was taken so I used my Instagram username

Have you checked all your ground points? Rear of the heads, chassis, etc?

Per another older post, 'Every bolt marked 2 is a ground. 4 and 6 on the front of the passenger head are also grounds'

While the diagram shows a 2010, the locations shouldn't have changed. I know you have had a lot of work done lately, especially with that Kraftwerks, so it's possible something is loose or was never connected.

I check just about every ground I know of. If something isn’t grounded, or has a poor ground, it should definitely be in the area that we were working around during the install. I’m really hoping it’s that stud on the alternator. Otherwise, I’m at a loss and don’t know what else to do.

i give you a tip 6 month ago remove my engine brackets to paint and give better look when put back gime the save mode dash light after 1 week i find have to shave the parts were the bolt hold the bracket and the alternator to remove the paint and finally work normal

Issue ended up being the B+ post on the alternator

Don’t you mean the negative ground stud per post18 ? BTW did you wind up replacing the alternator because of the chipped stud?
