I measure 1 ohm on a 1948 C. Perhaps someone has a more
sensitive meter. It probably makes a difference.

The parts manual lists the Delco-Remy part number as 814545.
Maybe it is still available thru Case/IH? Does your switch have
two resistor coils? One is the lighting dimmer, and the other
changes the feild resistance of the generator when the lights are
on. The field resistor coil in my C is a bare wire wound around a
piece of mica, and the dimmer is the double coil with insulation
directly on the wire.

Still trying to figure out all of this generator stuff, and every
tractor I look at seems to have a different combination of
generator, voltage regulator, and dimmer switch. It's also very
possible that a previous owner installed a new generator/VR,
which could negate some of the function of a resistor switch.
It's all very confusing. No wonder people install alternators.
