An automatic voltage Command device controls the sector current to keep output voltage constant. When the output voltage from the stationary armature coils drops because of a rise in demand, extra existing is fed in the rotating area coils in the voltage regulator (VR).

Some newer autos, and some 80's Chrysler merchandise, experienced the voltage regulator as portion in their Personal computer. Again, a good handbook will tell you the best way to do a bypass and examination the alternator. wiring assessments
