not really semantic. The GM speelling is what give us the "SENSING" therm, where actually switches on the regulator and gives the signal to cluster light. Beside the "sensing" wire on GM, they get the SOURCE wire for reg/rotor in a diff wire

the field wires on Mopars actually FEED the alt rotor to be able to produce the output power. No sensing at all

Is not just semantics, is a diff way to work.
