First, glad to see you kept your '44 at 6-volts. Next, no Ford N-Series Tractor had a generator with the cutout mounted on the barrel. The cutout was always mounted behind the dash. So, based on what you said, you have the wrong generator, probably from one of the car/truck modules such as the early V8 style as pictured below, and could be part of your problem. Your '44 2N would have used the 2N-10000-C generator. The unit is a 1-wire/3-Brush type, with the 3rd brush adjusting screw terminal on the rear end plate. It would also have the 2N tensioning bracket mounted directly on the barrel. It is basically the same as the 9N-10000-C generator only the 9N generator did not have the tensioning bracket mounted -it was a wrap-around band unit that came in a kit. All else was identical to the 2N style. The specs on both are: 11.5 AMPS output at 1200 RPM; CUT-IN VOLTAGE: MIN = 7.0 V, MAX = 8.5 V. If you are using a digital Multi-Meter, you will not get accurate readings due to field noise if checking while engine is running. Battery voltage needs to be checked static, that means under no use, engine off, lights off, everything off. Then a digital Volt/Ohm Meter will work fine. A negative reading on the AMP gauge indicates the wiring to the screw terminals on the back of it are reversed. Simply switch them around as there is no polarity involved with this application. If you have an original induction "LOOP-STYLE" ammeter, simply remove the wire feeding thru the loop and reverse it the opposite direction it is now. If interested, I just finished restoring a 2N-10000-C generator complete with the tensioning bracket, all the correct pieces included. My email is open.
