To reinforce what Trevor said, you can't test it with an ordinary DMM or a cheap universal component tester. Even a diode test range on a DMM is usually limited to 3V which may not be enough to turn it on. An Avo on a range that uses the 15V battery will work. Otherwise I'd suggest a 9V battery, 10K resistor and milliammeter.
