## Discrepancy

AFTER TURNING ON THE MASTER BATTERY SWITCH AS WELL AS THE ACFT FADEC (2) SWITCHES, NURSE SITTING IN THE CO-PILOTS SEAT POSITION BEGAN TO SMELL AN ODOR SIMILAR TO AN ELECTRICAL BURN.   CREW ALSO SMELLED THE ODOR.  DUTY CREW SAW A FAINT GLOW INSIDE THE CENTRAL INSTRUMENT PANEL.   IMMEDIATELY TURNED OFF FADEC SWITCHES AND MASTER BATTERY SWITCH,  GLOW AND ODOR SUBSIDED.    COMPASS LIGHT RESISTOR WAS FOUND BURNED OUT BEHIND THE RT PEDESTAL POWER DISTRIBUTION BOARD.   REPLACEMENT RESISTOR INSTALLED,  MX RUNS AND VISUAL CHECKS WERE PERFORMED, AND ACFT RETURNED TO SERVICE.
