## Discrepancy

WHEN TESTING THE EMER LIGHTS, SWITCH IN THE ARM POSITION NO EMERGENCY LIGHTS ARE ON INSIDE OR OUTSIDE. IN THE ON POSITION THE LIGHTS WORK. DID THE CHARGE PROCEDURE TWICE AND STILL DID NOT TEST IN THE ARM POSITION.   REMOVED SUSPECTED FAULTY #1 EMERGENCY BATTERY AND INSTALLED AS RECIEVED SERVICEABLE #1 EMERGENCY BATTERY. PERFORMED EMER BATT CHARGE. OPS CHECKS GOOD WITH NO OTHER DEFECTS NOTED AT THIS TIME. ALL WORK WAS PERFORMED I.A.W. CESSNA 660A MM 33-50-06, 33-50-06 AND 33-50-00
