## Discrepancy

NR 2 FORWARD LOW PRESSURE BOOST PUMP SLOW TO INDICATE.  *S/D*  TROUBLESHOOTING INDICATED THAT THE NR 2 FORWARD BOOST PUMP WAS OPERATING NORMALLY.  CLEANED CANNON PLUG D76 AT SUBJECT BOOST PUMP, REPLACED BOTH BOOST PUMP LOW PRESSURE SWITCH, AND THE BOOST PUMP ITSELF (AS A PRECAUTION).  PRIMED BOOST PUMP AND PRESSURE SWITCH SENSE LINE, OPS CHECK GOOD.
