temperature reading on the temperature analyzer. When the temperature difference exceeds the allowable tolerance, troubleshoot the aircraft system. Figure 10-78. EGT analyzer. EGT Indicator Check The EGT indicator is tested after being removed from the aircraft instrument panel ... temperature registered on the aircraft EGT indicator should be within the specified tolerance of the aircraft system and the temperature reading on the analyzer readout. When the temperature difference exceeds the allowable tolerance, troubleshoot the aircraft system…

being used. Figure 10-75. Troubleshooting turbojet engines. Figure 10-75. Troubleshooting turbojet engines (continued). Most analyzers may be used to: 1. Functionally check the aircraft EGT system for error, without running the engine or disconnecting the wiring. 2. Check ... accuracy. 5. Check the resistance of the EGT circuit. 6. Check the insulation of the EGT circuit for shorts to ground, or for shorts between leads. 7. Check EGT indicators , either in or out of the aircraft, for error…

Troubleshooting EGT System An appropriate analyzer is used to test and troubleshoot the aircraft thermocouple system at the first indication of trouble, or during periodic maintenance checks. The test circuits of the analyzer make it possible to isolate the troubles ... trouble mentioned. 1. One or more inoperative thermocouples in engine parallel harness. 2. Engine thermocouples out of calibration. 3. EGT indicator error. 4. Resistance of circuit out of tolerance. 5. Shorts to ground. 6. Shorts between leads. One or More…
