Here goes::::
What you have is almost assuredly a mixed bag of ingredients. We may have to do some weeding to make it correct. The generator should be a two brush Type "A" system. This means it should have a three pole regulator (only three)positive ground. The light switch (assuming it has Off D B positions)is working normally and should not be touched. Your generator with three brushes can be used as is with the third brush slid on its bracket as close to the other brush as possible. This system does seem to work if it is as described. The regulator will have (probably) two relays inside it. One is a cutout relay and it connects and disconnects the generators armature from the battery. It has fat wires wound around it in just a few turns. Leave it alone it seems to work correctly. The other relay is the voltage control. It works by viabrating its contacts chopping the field ground into bits (or pulses). This chopped up ground of the field reduces the effective field strength proportionally to the spring tension that is holding them together.
Adjust this spring tension to adjust the voltage of the output. With the tractor running and charging, turn on the lights and check the voltage across the battery. it should be about 7 7t 7.2 volts. If it is higher, the spring pressure should be increased to lower the output volts to the above. Do this carefully, some adjust with a screw, some adjust by bending a mounting tab of the spring with a needlenosed pliers (being careful not to shout anything out, it is trickie and alittle goes a long long way. When it is in the range, carefully put the cover back on and check the voltage again. (the cover modifies the magnetic field and can change the output) with the cover on, if the volts are low, or high, it will be necessary to remove the cover and adjust a bit to compensate, then re attach cover. When all is looking good, turn on the lights and check the volts. They should be operating correctly, and the volts should only drop off a little. The charge rate will vary as needed to keep the battery up.

If you want to change the gen. go to a two brush, and attach it the same way. Good luck, JimN
