Just my thinking!!
The Gen. is isolated from all connections to the battery when the cut out relay is open, and there is no rotation of armature. The cutout relay is a 6.5v voltage sensitive (lots of turns) coil that is connected on the Gen side to the armature, and to ground on the Cutout Relay box. It also has a hold in winding that is heavy wire and connected to the contacts, through them when closed to the battery.
The cutout closes as residual magnetism in the field poles (reason for polarization) generates enough voltage in the armature to close the cutout relay through its small many turn winding to ground. When it closes, the battery is connected to the arm. windings. The field windings are in the circuit when the contacts are open providing another path to ground through the L H switch on the elect box. Current through the field also self excites the generator. If the field were internally shorted, the resistor would glow. In my opinion. Even if the contacts on the cutout never closed.
Very interesting, JimN
