## Discrepancy

PHX - MAINTENANCE REPORTED THE EMERGENCY EXIT SIGN AT MID CABIN CEILING WAS INOPERATIVE.  MAINTENANCE FOUND A BROKEN WIRE ON THE EMERGENCY EXIT SIGN.  DISCOVERED THAT BROKEN WIRE SHORTED OUT POWER SUPPLY.  REPLACED BOTH THE EMERGENCY EXIT SIGN AND POWER SUPPLY PER MM 33-51-51-2.  OPERATIONAL CHECK GOOD.
