Might want to make sure the 1000uf 25 Volt filter cap that's on the 12-Volt DC relay supply has not gone bad. If it's original it should have by now.

Other possibility is that the "keying" relay is not closing the circuit that activates the HV relay.

Does yours have the plug-in board with 3 relays, or the wired-in relay board with one plug-in relay?
