## Discrepancy

NR 3 ENGINE OIL PRESSURE LOW TO RED BAND ON TAKEOFF ROLL.  ABORTED TAKEOFF.  *S/D*  CLEANED THE ELECTRICAL CONNECTOR TO THE OIL PRESSURE TRANSMITTER AND SWAPPED THE NR 1 AND NR 3 GAUGES TO ISOLATE THE PROBLEM.  IT SHOWED THAT THE PROBLEM WAS WITH THE INDICATION AND NOT TRUE OIL PRESSURE.  THE OIL PRESSURE TRANSMITTER WAS CHANGED AS A PRECAUTION.
