QUOTE: " The regulator senses the loading on the vehicle's electrical system, and adjusts the field current in the alternator to adjust the amount of current that the alternator produces."

My quote is basically the same thing .."The Voltage regulator is what provides the current on demand"
I wasn't getting into all the specifics of the charging system.

The point was that when the demand for current is required the voltage regulator is what triggers the system to provide more

The alternator NEVER stops turning while the engine is running no what the RPM is so it is the VR that is the brains of the system
