What was found
AFTER CHARGING EMERGENCY LIGHT BATTERIES FOR 60 MINUTES, THE EMERGENCY LIGHTS FAIL PREFLIGHT TEST. WHEN BATTERIES ARE OFF AND EMERGENCY LIGHTS ARE IN ARMED, NO EMERGENCY LIGHTS TURN ON. THE EMERGENCY LIGHTS DO TURN ON WHEN IN THE ON POSITION. PERFORMED T HE OPERATIONAL CHECK OF THE EMERGENCY LIGHTING SYSTEM PER AMM 35-50-00 AND T HE EMERGENCY LIGHTS OPERATED NORMALLY WITH NO DISCREPANCIES NOTED. AFTER SPEAKING WITH TEAM 700 THEY ADVISED THE EMERGENCY LIGHTS SHOULD NOT COME ON WITH THE BATTERIES DISCONNECTED AND EMERGENCY LIGHT SWITCH PLACED INTO THE ARM POSIT ION. PER TEAM 700'S RECOMMENDATION WE PERFORMED THE OPS CHECK ONCE WITH BATTERIES ONLY, AND AGAIN WITH EXTERNAL DC POWER ONLY, BOTH CHECKS YIELDED THE SAME CORRECT RESULTS PER THE AMM, NO DISCREPANCIES ARE NOTED AT THIS TIME
