the step to test second chamber(low pressure side) on the regulator is the same for single or double stage regulators.

at this point, Mathman, you need to return that regulator if it is possible, and remember when you buy a used regulator, spend a little bit more to buy a good condition one so less chance you meet problems. These second hand regulators are dirt cheap anyway, compare to their original retail which is hundreds a piece or even more than thousand dollars a piece.
