## Discrepancy

X FEED LIGHT IS BLINKING TO BRIGHT BLUE WHILE SWITCH IS SELECTED CLOSED. GROUNDED - YES. T/S PER FIM 28-22 TASK 807. CROSSFEED VALVE SWITCH CKS GOOD. TRANSFERRED FUEL BETWEEN NR 2 AND NR 1 TANK AND OPEN AND CLOSED VALVE DURING TRANSFER AND VALVE OPERATED NORMALLY. NO PREVIOUS HISTORY LAST 30 DAYS. CK'S GOOD FOR SERVICE.
