The positive rail voltage shows up on the cathode of D310 so the coil is not energized. I checked the path between the B+ rail through R346, D310 to pin 6 of IC310 and there are no open components/traces.
I assume the coil needs to be energized to switch the relay terminal 2 to terminal 3 - closed path? If that's the case then IC310 is suspect - what are the +-VCC pins?
