Stock alternators, yes.

A clamp on meter can read the amperage.

- One on the back of the engine head for the engine harness
- One on the intake header for the engine harness
- One for the MAF through the engine harness
- And then I have a dedicated grounding harness that grounds the chassis, alternator body, intake manifold, ground behind the headlights.
One thing I have noticed, I'll hear a whining sound coming from the speakers when the car is running and it kind of gets louder when I turn on the lights.
Right now, I'm thinking about removing that grounding harness to see if that makes a difference. IDK if I'm properly grounding the alternator. There's a bolt that screws into the body and I have a wire going from that to the chassis. I have good continuity between the alternator and the chassis. I don't have a good contact from the alternator body through the bracket to the engine, but that grounding wire should still be fine, right?

If you are relying on just the threads at each ground location, I would advise you to remove the connection, sand the paint until bare metal is visible and add a dab of dielectric grease. Reinstall grounds.
