If you have a cheeeep digital meter, it may not be capable of biasing the diode in question enough to turn it on. Use a 12V bulb and put each half of the isolator in series wioth the bulb and battery. One direction it should light, the other stay dark. If it kights both ways, that diode is shorted. If it doesn't light at all, that diode is open.
