Pin 31a and 30a are leads to a diode... set VOM on ohm and check, then reverse polarity. One way should show continuity, the other should not...

Usually, the diode shorts out and allows current both ways when faulty, but can also blow "open".

Not sure about the resistor, indicated on the schematic, so any check there for me, would be for continuity. If none, then probably blown open as well...
