Hi. I have what seems like an easy question, but I'm having trouble answering it myself. As say a standard 3-phase car alternator has a heavy load placed on it, the voltage regulator would increase the current into the windings creating a greater magnetic field and thus increasing alternator current output. But why would voltage decrease through the car as the load became heavy? It would seem that the voltage would increase (or at least maintain it's maximum regulated level) as alternator current output increased, until the maximum regulated alternator output was reached, and at that point would still be maximum. Thanks for any info.
