Judging by the photo MichaelB posted, the 12v wall brick plugs into a jack near the rear center of the board. With the clock plugged in, measure the voltage across the metal lead at the back of the jack (positive) and the exposed part of the plug. You may have to withdraw the plug slightly to give you room for your meter lead.
