## Discrepancy

CLT - FLT 2673 - EN ROUTE FROM BOS TO TPA, THE APU EGT GAUGE WENT TO ZERO DURING FLIGHT.  THE APU WAS IN USE AS THE NR 1 GENERATOR WAS ON MEL.  FLIGHT DIVERTED TO CLT AND LANDED WITHOUT FURTHER INCIDENT.  NO EMERGENCY WAS DECLARED.  MAINTENANCE FOUND A LOOSE CONNECTION ON THE EGT HARNESS CONNECTOR.  TIGHTENED CONNECTOR.  REMOVED AND REPLACED APU EGT INDICATOR (P/N 152BL802A) AS PRECAUTIONARY.  OPS CHECK GOOD.  (M)
