## Discrepancy

RIGHT HYDRAULIC PUMP PRESSURE LIGHT ILLUMINATED WITH SWITCH IN AUTO.   MAINT FOUND NO VOLTAGE AT RT HYD EDP CONNECTOR D486 (WDM 29-11-22) WHEN SWITCH IS "ON" OR "AUTO".  WHEN SWITCH IS ROTATED PART OF THE WAY, PRESSURE COMES ON & STAYS ON.  SWITCH SUSPECTED ON OVERHEAD HYD SYSTEM CONTROL PANEL.  REPLACED RT HYD PUMP SELECT SWITCH S7 AT P5 PANEL.  OPS CHECKED HYD SYSTEM OKAY.
