## Discrepancy

(CAN) THE INDICATOR LIGHT FOR THE NR 1 HYD SYS WILL NOT EXTINGUISH WHEN POWERED BY THE HYDRAULIC CART NOR WILL THE RESERVOIR DRAIN INTO THE HYDRAULIC CART. (SUSPECT THE TEST SCREW ORIFICE IN THE VALVE BODY IS PLUGGED). THE HYDRAULIC POWER PACK ASSEMBLY WAS REPLACED AND GROUND CHECKED SERVICEABLE. THE SUSPECT ASSEMBLY WAS SENT FOR REPAIR.
