## Discrepancy

ON TAKEOFF ROLL, NR 2 EPR WOULD NOT ADVANCE PAST 1.4.  ALL OTHER ENG INDICATIONS WERE NORMAL.  REMOVED AND REPLACED NR 2 ENGINE EPR TRANSMITTER IAW AMM 77-11-011-4.  NO HELP.  RAN NR 2 ENG TO MAX PWR AND EPR INDICATION WOULD GO TO 1.6 EPR AND DROP TO 1.4 EPR WITH PWR ADVANCED.  CONNECTED NR 3 EPR WIRING TO NR 2 EPR XMITTER.  ENG CKS GOOD.  WITH NR 3 ENG CONNECTED TO NR 2 WIRING GOT NO EPR INDICATION.  WIRING IS SUSPECTED PROBLEM BETWEEN NR 2 EPR XMITTER AND NR 2 EPR INDICATOR.
