Negative battery cable in accordance with the TSB.

Just a thought, but doing the big 3 upgrade would also be a good idea. By doing that would it matter if the special coverage was done or not?

The Big 3 upgrade bypasses the Negative Battery Cable, so they are effectively the same.

Just test your cable. As you know the bigger the cable the higher current capacity. The more current that flows through a cable the more resistance it generates. If you have a bad connection corroded strands etc., it is essential like the cable if undersized and generate a much higher resistance. To test the cable you can check the resistance or simply put it under a load. Measure dc voltage from one end to the next. If you have voltage more than a few mV you have a problem. To be precise you can calculate the current flow and capabilities of the cable but we will not get into that. Just turn the lights on for a few minutes to drain the battery some. Check voltage between neg battery term to the engine and chassis. Then start the engine and check again. Also check chassis to engine to check the ground on the engine.

To the OP,
A service bulletin was created due to the fact many negative battery cables were incorrectly manufactured.
The crimp joint where the cable is inserted into the terminal was compromised during manufacture and over time, resistance builds up making all sorts of electrical mayhem.

The cable should be replaced "warranty" before any troubleshooting takes place.

Why the attitude towards GM? They have fixed this cable - get the new cable from them for free.

Well, at 151k I understand why no freebe.
The warranty was extended to 120k memory serves.

But at your current mileage, the potential for lots of nickle and dime (or dollars) failures is pretty much a guarantee......machines are machines and every mile traveled is one less it has to give.

So, regardless of expense, do the cable since it was a known weak spot and see what happens from there.

In this case it's definitely out of the extended warranty on the cable. I think I'd still purchase the redesigned cable and install it. The fact that GM extended the warranty on this cable screams supplier error.

It's possible the alternator can't create enough amps at low RPM. If it drops to 11.5 only momentary, I wouldn't worry about it.

To the OP:

It's sounding more and more like you don't fully understand the car and are simply throwing parts at it.

I know that you don't like going to the dealer - but this may be one of those times when paying for someone qualified to work on your car may save you money.

Yes. The alternator is clutched. It cuts off during acceleration and other scenarios when extra power is not needed or will save fuel.
