The following schematic shows the wiring circuit of Delco-Remy 1118200 type. Three-unit regulator shown, the shunt windings in the cutout relay and voltage regulator are shown in dashed blue. The regulator contains a cutout relay, a voltage regulator, and a current regulator. The current regulator has a series winding of a few turns of heavy wire (shown in red) which carrier all generator output. The winding core is assembled into a frame.
