That is a cutout relay not a voltage regulator. The blue wire (looking newer) is the field connection, the older blue wire under it is the armature connection, the red wire connected in back is going to the ammeter. (or battery if the ammeter is disconnected). The old cutouts have a wire wound resistor under the bottom that provides a low level of constant charge rate, by providing a ground for the field (which gets its voltage in the inside of the generator, and is grounded to make it operate. If you disconnect the red wire, it should show 6v on the wire, and nothing on the terminal it was connected to. The red wire should be a #10 gauge if it is not. The taped up wire should be removed. This tractor was probably purchased without lights. It is simple and worked OK for the time it was made. If you want to have it regulator controlled, let us know and we can make it work a little more in the modern direction. Jim

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
