I also have found a few junkyard cores with the little wire wound resistor. I really dont know what application would require that part or what it does, they seem to work with or without it ? Bob seems to have a lot of experience with that model alternator, Bob, can you que us in as to what that little resistor does and what machines use it. ?? I also have uesd an ohmmeter on used regulators with readings that vary a lot. They all seem to work within normal voltage specs, so I suspect that different brand regulators are built to different specs.
Testing a used regulator is not hard if you have access to a variable voltage power supply that can supply atleast 16 volts. You connect the + terminal of the power supply to the two regulator blade connctions and the - terminal to that ourboard screw hole where the un insulated screw goes, and connect a 12V test light across the other two terminals. When you apply voltage, the test light should glow until the voltage exceeds 14-15 V where the light will go out. As soon as you lower the voltage below that 14-15 V again the light should come back on. This indicates a working regulator that is within normal specs.

But alas, my carb foiled me again, it would fire a second then flood out. After numerous dead ends for a replacement carb, I went to work fixing mine.I soldered new floats on the float arm, they came from an old motorcycle carb, replaced the packing on the throttle shaft with o-rings, cut new ga
