I see the generator light is connected to both the instrument light wires and the generator wire. Do they just connect one wire to each side of the bulb and rely on that difference in voltage to light it? If so, then it would make sense why mine is not lit as my voltage regulator and generator are both off the car currently.
That is correct. With no output the generator windings provide the ground path from the battery, thru ign sw and cluster fuse, bulb, generator windings and finally to ground. As soon as the generator starts putting out enough voltage to close the cutout relay contacts the bulb filament path is completely bypassed by the hard contact connection so bulb goes out.
If generator voltage output falls enough to open the cutout contacts then depending on how much voltage is still being produced by the generator, current will flow from the battery side thru the bulb to the generator side and bulb will either be on constantly but be dim. It can also flicker when the engine slows to idle if the cutout relay setting closely matches the reduced generator output so cutout contacts are opening and closing.
