>So the cutout contacts DO carry the lighting load supplied by the generator, but that current is apparently unregulated.
Voltage regulated yes; but current regulated no.

>So, you are saying regulators with the "L" terminal are only used on 3-brush generators?
Don’t know that for sure. My 2-brush generator experience is limited to Oliver tractors and IHC/GMC/Mack trucks from the late 50’s/early 60’s. (All had 3 terminal VR’s)

OTOH back in the day there were no electrical loads beyond the factory work lights. Accessory loads like heater blowers, wipers, sound systems, etc. were still in the future. Further, supplemental lighting beyond the factory-supplied lights had yet come into vogue. So the risk of an overloading a 2-brush generator thru the L terminal may have been too small to worry about.
Only after the shortcomings of 4 terminal regulators mentioned by Pete 23 were recognized - also probably more than a few overloaded generators burned up by their owners - was the design changed to 100% generator current regulation.
