## Discrepancy

DURING A GROUND INSPECTION IN ATL, THE EMERGENCY LIGHTS CAME ON WITH THE SWITCH IN THE OFF AND ARMED POSITIONS.  MAINTENANCE FOUND CIRCUIT BREAKER P4-C2 POPPED AND THE EMERGENCY LIGHTS BATTERY PACKS LOW RESULTING FROM BOTH MAIN AND AUXILIARY POWER UNIT BATTERIES BEING DISCONNECTED WITH THE SWITCH IN THE ARMED POSITION.  MAINTENANCE RESET CIRCUIT BREAKER P4-C2 AND ALSO RECHARGED THE BATTERY PACKS.  OPS CHECKS GOOD.  AIRCRAFT OK FOR SERVICE.  (M)
