## Discrepancy

ON SERVICE CHECK FOUND FLIGHT DECK EMER LIGHT NOT WORKING.  DISCONNECTED THE FWD & AFT EMER LIGHTING POWER SUPPLIES & THEN RECONNECTED BOTH.  ACFT WAS POWERED UP FOR APPROX 2 HRS, THEN RAN THE POWER SUPPLY TEST ON EACH IAW MM 33-51-07-02.  BOTH POWER SUPPLIES WORKED & ALL EMER LIGHTS ILLUMINATED.  RAN THE EMER LIGHT TEST, ALL EMER LIGHTS ILLUMINATED.  ACFT OK FOR SERVICE.
