OK, if we can assume you did the generator motoring bench test, and if we can further assume it is all properly connected with the correct voltage regulator (oops, you said that may not be), If you run the motor at 2000 RPM or more, there should be a charge showing on the amp meter. Max charge rate is 10 AMPs which it should do, it the battery is not totally charged. It will not charge at idle speeds.
If it does not show a charge at 2000 RPM, check the 4A fuse in the junction box. And make sure the fuse is making good contact in the fuseholder clips. If still no charge with a good fuse, CAREFULLY ground the regulator Field terminal. I emphasize carefully because it you accidently touch it to the nearby terminals, the smoke will get out of the regulator. If it shows a charge with the Field terminal grounded you know the generator is working, but regulator is not. Immediately unground it and double check your wiring. If all wiring is ok, replace regulator.
Other tests confirm the 10A maximum and voltage settings, but that is another subject.
Concerning the regulator: It uses a 10Amp, 12V, "A" field regulator. No car that I am aware of uses such a thing, so forget about car regulators.
