All of the Following Statements Are True EXCEPT

All of the following statements are true EXCEPT:

A) the powertrain control module (PCM) , or voltage regulator controls the current passing through the windings of the electromagnetic field in the rotor.
B) the voltage regulator can be located on either the ground side or the positive side of the field circuit.
C) electronic voltage regulation requires no moving parts, so it can cycle electronically between 10 and 7,000 times per second.
D) turning the AC generator rapidly on and off to achieve a precise output is called voltage width modulation.
