(2) If the electrical connections of the EGT 1 THERMOCOUPLE is OK:
- use a multimeter to do a resistance check across the terminals: chromel and alumel of the EGT 1 THERMOCOUPLE; required value < 20 Ohms and chromel and grounded EGT 1 mount flange; required value > 100 kOhms and alumel and grounded EGT 1 mount flange; required value > 100 kOhms.
(a) If the resistance values are out of the specified limits:
- replace the EGT 1 THERMOCOUPLE (Ref. AMM TASK 49-72-15-000-002) and (Ref. AMM TASK 49-72-15-400-003).
(b) If the resistance values are in the specified limits:
- do a check of the aircraft wiring from the ECB (59KD) AB/A6,A7 to the EGT 1 THERMOCOUPLE terminals chromel/alumel (Ref. ASM 49-61/01).
