Question is, when the ECM decides that the 'clutch mechanism', in the alternator, that has to engage, and become more of a load on the motor, ... ?

The alternator is ALWAYS spinning...

How DOES the integral voltage regulator work, I guess, is the question???

The voltage regulator is internal to the alternator and is autonomous. When there is low demand from system (Battery >12.2v ?) the field winding is left at 0V and the alternator free wheels. i.e. no load.
With no load it's just another idler pulley.

The big win on moving to low current draw by switching to LED everywhere is the available capacity to run "more stuff" in the cabin.

It allows the alternator to idle as the demand is not needed. Remind me to tell you the story when one of our 400KV voltage generators regulators failed and provided instant 100% power to our living area one night in Iraq at 0200hrs. Everything that had a power supply was burned out. Lamps that were not switch on turned on until the generator exploded with sparks flying over the T-walls. We though initially it was an RPG attack.

Less demand on your electrical system is a "goog" thing
