If the meter is working, be very careful testing the continuity with a meter, because it takes less than 100mV/30uA to peg it. So a DVM can easily destroy the meter, depending on the meter. Put something like 47k in series. If it is already open you'll clearly read an open circuit. If the meter is OK, you'll read around 50k and the meter will read something less than full scale.
