I have a dash mounted volt meter. Unplugging the 4P plug will always keep the alt completely off. It cannot power-up itself through the thick white charging wire to the battery. My switch disables two of the wires in the 4P connector. If the alt is running and I cut the switch, the alt still charges until I cut the injectors and bump start again. But according to some, a small light on the line can drain the residual charge in the field windings (I have not tried this).

You might try taking the powr steering belt off as a test of this idea. It's easier than an alt disable and completely reversible.

I believe the answer might be yes, because the alt will be generating power with nowhere to go. But why would you want this? The power generation itself would still be a parasitic draw on your engine.
I hope those answers help.
