B. Test
(1) If the circuit breaker (1RT2) trips, refer to Para. 4. C. of this trouble shooting procedure.
(2) Do the BITE test of the ILS (system 2) (Ref. AMM TASK 34-36-00-740-002).
- If the BITE test is not possible, refer to Para. 4. B. of this trouble shooting procedure.
4. Fault Isolation
_______________
A. If the circuit breaker (1RT2) is closed, and if the BITE test gives the maintenance message ILS 2 (1RT2):
- replace the RECEIVER-ILS, 2 (2RT2) (Ref. AMM TASK 34-36-31-000-001) and (Ref. AMM TASK 34-36-31-400-001).

B. If the circuit breaker (1RT2) is closed and if the BITE test is not possible
- do a check for 115VAC at pin AC/2 of the ILS receiver 2.
(1) If there is no 115VAC:
- do a check of the wiring of the 115VAC signal from circuit breaker (1RT2) to ILS receiver 2 (2RT2) (Ref. ASM 34-36/01).
(a) If there is no continuity:
- repair the above wiring.
(b) If there is continuity:
- replace the C/B-ILS/2 (1RT2).
(2) If there is 115VAC:
- do a check of the wiring of the ground signal at ILS receiver 2 pin AC/3.
(a) If there is no continuity:
- repair the above wiring.
C. If the circuit breaker (1RT2) is open:
- close this circuit breaker.
(1) If the circuit breaker (1RT2) trips:
- remove the RECEIVER-ILS, 2 (2RT2) (Ref. AMM TASK 34-36-31-000-001).
- close the circuit breaker (1RT2).
(a) If this circuit breaker stays closed:
- install the ILS receiver 2 (Ref. AMM TASK 34-36-31-400-001)
1 If the circuit breaker trips again:
_
- replace the ILS receiver 2 (Ref. AMM TASK 34-36-31-000-001) and (Ref. AMM TASK 34-36-31-400-001).
(b) If this circuit breaker trips again:
- do a check for a short to ground at the wiring between the circuit breaker (1RT2) and the ILS receiver 2 (2RT2) (Ref. ASM 34-36/01).
1 If there is a short to ground:
_ - repair the above wiring.
2 If there is no short to ground:
_ - replace the C/B-ILS/2 (1RT2).
3 Install the ILS receiver 2
_ (Ref. AMM TASK 34-36-31-400-001).
D. Do the test given in Para. 3.
