- do a check for a ground signal at pin AC/5 of the rack connector.
(1) If there is no ground signal:
- repair the aircraft wiring between ADIRU1 pin AC/5 and the first terminal block (Ref. ASM 34-11/01)
- install the ADIRU1 (Ref. AMM TASK 34-12-34-400-001).
(2) If there is a ground signal:
- do a check for 115VAC at pin AC/1 of the rack connector.
(a) If there is 115VAC:
- install a new ADIRU1.
(b) If there is no 115VAC:
- do a check and repair the wiring between the ADIRU1 and the circuit breaker (4FP1) (Ref. ASM 34-11/01)
- install the ADIRU1.
B. Do the test given in Para. 3.
