I forgot to ask earlier, while the generator was still on the tractor did you happen to put a volt meter on the armature side and see if/what it was outputting?

I didn't think to check the voltage off the generator when i had it running unconnected.
I have a large variable resistor that I can hook up like the testing documents show as a "dumb" load and put an ammeter on that and a voltmeter to see if its behaving right if i ground the field coil.
