## Discrepancy

EMERGENCY LIGHTS DID NOT ILLUMINATE WHEN POWER ON CHECKLIST WAS BEING COMPLETED. PERFORMED AN OPS CHECK OF THE EMERGENCY LIGHTING SYSTEM PER AMM 33-50-00-710 AND DETERMINED #4 ERNER LIGHTING BATTERY CHARGER TO BE DEFECTIVE. REMOVED AND REPLACED #4 ERNER LIGHTING BATTERY CHARGER WITH A REPAIRED UNIT PER AMM 33-50-06 AND OPS CHECKED GOOD.
