## Discrepancy

PILOT REPORTED BURNING OR HOT ODOR ON SHORT FINAL.  WHEN ACFT WAS SHUTDOWN, PILOT OBSERVED THE FLAP POSITION LED AND THE KEYPAD BACKGROUND LIGHTS WERE STILL ILLUMINATED AND CIRCUIT BREAKERS FOR THE NR 2 BATTERY, YAW SERVO AND AUTOPILOT CONTROL/KEYPAD WERE TRIPPED.  ATTEMPTED TO TRIP ALL ACFT CIRCUIT BREAKERS, THE INDICATIONS REMAINED.  DISCONNECTED THE NR 1 ACFT BATTERY AND INDICATIONS STILL WERE PRESENT.   DISCONNECTED AIRCRAFT NR 2 BATTERY.  WHEN REACHING IN TO THE COMPARTMENT A SPARK OCCURED.  SPARK WAS DUE TO THE NR 2 BATTERY WIRING CONTACTING THE YAW SERVO WHICH SHORTED OUT TO THE RT FORWARD ELEVATOR CONTROL CABLE.    NR 2 BATTERY POSITIVE WIRE BURNED THROUGH.
