## Discrepancy

ON DECENT THE FO NOTICED THE #1 & #2 AC GEN CAUTION LIGHT FLICKERING, AS WELL AS THE MASTER CAUTION LIGHT. REMOVED FROM SERVICE. FOUND FAULT CODE 28 "#2 AC GCU" IN EPCU. COMPLIED WITH Q400 FIM TASK 24-21-06-810-802, PARA 1 THRU 3.D. OPS TEST OF AC GEN SYSTEM IAW Q400 AMM 24-24-00-710-801 IS GOOD. FAULT CODE DID NOT RETURN. OKAY FOR SERVICE. NO PARTS REPLACED. AIRCRAFT RETURNED TO SERVICE.
