## Discrepancy

DURING CRUISE, PILOT NOTED THE RH CIRCUIT BREAKER PANEL BACKLIGHTING WAS FLASHING, FOLLOWED BY A MOMENTARY SMELL OF ELECTRICAL BURNING.  THE BACKLIGHTING WAS TURNED OFF AND THE SMELL DISSIPATED.  MAINTENANCE LOOKED AT THE ISSUE ON ARRIVAL TO ANC AND NOTED THAT THE POSITIVE TO NEGATIVE TERMINAL IN THE CONNECTION ON THE PANEL HAD SHORTED TOGETHER.  EL PANEL WAS REMOVED AND PARTS ORDERED TO REMEDY.  SYSTEM IS CURRENTLY DEACTIVATED AND ON AN MEL UNTIL PARTS ARRIVE TO CORRECT.  A FOLLOW UP TO THIS SDR WILL BE SUBMITTED ONCE MEL IS CLEARED.
