Assuming your polarities are correct (I believe they are) the only possible answer is that the generator is shorting to ground internally. It could be many things, but there is no way it should make warm wires doing the test. Disconnect the gen from all wires. If you can get through the endframe, to the brushes, use a pic or pointed wire to lift them off of the armature. Put a piece of card stock under them to insulate them from the commutator bars. Then test the resistance of the Arm terminal to ground. If it shows ground, it has a short. If not, it will require disassembly of the gen to test the armature for shorts.
