## Discrepancy

DURING LAYOVER CHECK, MX FOUND THE EMERGENCY EXIT LIGHT AT DOOR 1R TO BE INOPERATIVE.  A BLOWN FUSE (F1 ON POWER SUPPLY M731) WAS IDENTIFIED AND THE POWER SUPPLY WAS  REPLACED.  AFTER REPLACEMENT OF POWER SUPPLY ENTIRE FIRST    CLASS AISLE EMERGENCY LIGHTS WENT INOPERATIVE DUE TO A WIRE SHORTED AT 3CD. REPAIRED THE FAULTY WIRING IAW WDM AND LIGHTS NOW OPERATE NORMAL.
