I m not sure what you have going on anymore. I think in order to be sure what is happening you will need to start testing again but with a known good regulator. There is a chance yours might have been damaged.
As you can see from this diagram of a typical generator charging circuit, by using the FIELD terminal when you polarized that put full battery voltage and current across some resistors in the regulator and the current and voltage regulator contacts which internally connect to ground. With one side of the resistors grounded the large current flow thru them could have changed their resistance or burned them open or the regulating contacts shown above the resistors that control whether they are in the circuit could have been damaged. There might be no damage at all but still it is unknown if the regulator is functional. You could still ground the field terminal to see if the generator will put out maximum voltage but that is about as far as you could go.
