## Discrepancy

WHILE ON THE GROUND, MAINTENANCE FOUND THE EMERGENCY LIGHT BATTERY PACK METER SHOWING ON, WHEN EMERGENCY LIGHTS WERE OFF.  A/C BATTERY PACK METER NEEDS TO BE DEACTIVATED AND PLACARDED.  MAINTENANCE DEACTIVED THE METER PER WDM 33-50-01, OK TO CONTINUE SERVICE.  INSTALLED DEACTIVED STICKER PER 34-21-04, EFIS WDM FOR FURTHER INFO.
