OK Tiger, now that we have a few more important pieces, what exactly do you have -see PIX below? Is it/was it running now? How did you determine it has 2 brushes? You'd need to inspect the unit internally to do that. A 1-Wire unit would be the 2N GEN (or 9N-10000-C) and a 3-Wire Unit would be the 8N-10000- GEN. The 9N-C & 2N unit use the roundcan cutout. The 8N unit uses the rectangular Voltage Regulator. Both have the Third Brush Adjustment Screw on the Back End Plate -see PIX. Do get you running, you need to get the correct 1-Wire 2N GEN with the cutout and the correct wiring harness; or, if you have the 8N 3-Wire/3-Brsuh unit, get the 8N-10505-B Voltage Regulator AND a new wiring harness to wire it correctly AND get a copy of the Service Bulletin on how to install the 8N GEN & VR in a 9N/2N tractor; or, opt to just go with a 12V switch over job. The latter will involve a 12V battery, a 12V alternator, new belt, belt tension device for the alt, and new wiring. As stated now a few times, forget about s/n and model year, get the wiring diagrams from JMOR and the OEM Manuals as shown and use the as your guide.
