Disconnect the field wire then short. Not on the regulator.

Also, as Howard said last, check the grounds. With the car off, ohm between the case of the generator, and the positive battery terminal. Likewise from the case of the regulator to the battery positive terminal. Each reading should be under an ohm or so (consult service manual for more specific guidelines on this test). If it is a high value, your problem is a poor ground connection on the regulator and/or generator.

Though a poor regulator ground I would imagine would cause an overcharging condition, not under.
