Dead like the relay itself is dead, or no power to the relay? How are you testing the relays? Should see a short across the control points, and either a short or an open across the feed ports depending on the relay configuration. You should also see a change across the feed ports, once again depending on the relay configuration, when power is applied across the control points.
If there is no power to the relay ports that the relays plug into (check by probing the relay ports directly with a voltmeter, at least one should be live, may need the key in the on position) then the relay center feed would need to be checked to ensure that the relay center itself has power.
