## Discrepancy

EGT'S ALL READING ERRATIC DURING CLIMB-OUT FROM KMIA.  OFF FLAGS FOR NR 2 COMES ON ERRATICALLY, NO LIGHTS COME ON.  OPERATIONAL NORMAL AT ENGINE START AND CRUISE FLIGHT.  RETURNED TO KMIA.  NO FUEL DUMPED.  REMOVED AND REPLACED VERTICAL SCALE EGT INDICATOR IN ACCORDANCE WITH AMM 77-21-03.  OPERATIONAL CHECK GOOD.
