I'd be checking to see if there's a draw on the battery while the ignition is off.

What voltage are you getting from the UFB lug to chassis ground with the engine running?

I shouldn't use obscure abbreviations, or initialisms, or acronyms ....
UFB = Underhood Fuse Block. The lug would be the battery cable lug that is under the flip-open red cover.

Occupational hazard, I imagine. I do the same thing all the time, in a different context.

13 volts when engine is off. Right at 12 when running.

That's weird. I'd expect 14+ when running, 12-13 when off.

I don't know how you did the bench test of your generator, but I suspect that it is bad.

Edit: Also check your serpentine belt to be sure it is tensioned properly, and not slipping.

The manual states 12.6 to 15.0 volts at 2500 RPM during a 90 Amp load test, so it should certainly be in that range running normally.

I agree with raygun, and mine (I just checked) reads 14.4 V at idle.

I had it tested at the parts store bench. everything tested good. After installing it back on the car, I started it up and pulled the neg cable. Dies instantly. Guess I'm off to get a new alternator! Could I have any of the wiring connected wrong? With it running fine with a good battery, I don't think this could be the case.

If your grounds are all good, then it should keep running with the negative cable removed. That's how I've tested alternators in the past, successfully - though I haven't tried it on the Solstice.

I'm going to ramble out some wild-ass guesses:

If it was only putting out 12V when running, then either something is pulling the voltage down (most likely by drawing a ton of current) or the alternator isn't doing its job properly. That could also trigger the battery light (which is really, I think, a charging system light).

As @JohnWR said, a loose alternator belt could cause low alternator output. But, given how simple the tensioners are on this thing, it's pretty difficult for it to have a belt that's *not* tensioned correctly. You said that you used the accessories from your old engine. Did you also use the old tensioner? Is it properly tightened to the block and keeping the belt tight? If the tensioner is bad, you should be able to see some play in it. The belts should be normal "belty tightness." If you reconnect the battery and start the car, can you see significant bounce in the belt or tensioner?

Did you recharge the AC yet? Make sure the AC is off when you're running this. If it was improperly charged and the clutch is engaged, it *may* put too much load on the system. (Again, I'm guessing here.)

If you have a cheap scanner, like this:

https://www.amazon.com/gp/product/B00WPW6BAE/

And a smartphone app like DashCommand (or Torque for Android people), you can see what the ECM thinks the voltage is, among other things. But, I'd expect that to be the same as what your multimeter is telling you.

Current thought is that you should not disconnect the battery while the engine is running. The battery acts as a buffer that absorbs spikes and other electrical noise that can damage the electronics in the car.

If the voltmeter measured 14V I would be concerned that the car didn't know the correct voltage, but since the measured voltage is consistent with the fault indicator I wouldn't go that route.

Also, this may sound silly, but it's come up before:

Are you sure it's the battery light and not the "low coolant" light?

Re-read posts 15 and 21. He actually has low measured voltage and charging faults from a tester.

I read, and responded to, those posts. But, OP also said that the car runs fine. Thus, my question.

I thought you were maybe like me and had read and answered so many posts that you lost track.

I can understand mistaking the coolant light for the battery light absent any other symptoms, but if the generator actually tests as "not charging" and the voltage is actually measured at 12V running, it seems like there has to be a "real" problem.
