4. Fault Isolation
_______________
A. If the test confirms the fault:
- do a check of the circuit breaker 15WN status (Ref. ASM 52-73/01).
(1) If the circuit breaker is closed:
- do a check for 28VDC at pin A of the indicator light (3WN2) (Ref. ASM 52-73/01).
(a) If there is 28VDC
- replace the IND LT-SLIDE ARMED, AFT R DOOR (3WN2), (Ref. AMM TASK 52-73-21-000-001) and (Ref. AMM TASK 52-73-21-400-001).
1 If the fault continues:
_
- do a check for a ground signal at pin C of the proximity switch (17WV2), (Ref. ASM 31-54/05).
a If there is a ground signal:
_
- do a check and repair the wiring from the proximity switch (17WV2) to the indicator light (3WN2), pin B to pin F, (Ref. ASM 31-54/05) and (Ref. ASM 52-73/01).

b If there is no ground signal:
_
- repair the wiring from the proximity switch (17WV2) pin C to the ground, (Ref. ASM 31-54/05).
(b) If there is no 28VDC:
- do a check and repair the wiring from the indicator light (3WV2) to the indicator light (2WN2) pin A to pin B, (Ref. ASM 52-73/01) and (Ref. ASM 52-73/01).
1 If the fault continues:
_
- replace the IND LT-SLIDE ARMED, R EMER EXIT (2WN2), (Ref. AMM TASK 52-73-21-000-001) and (Ref. AMM TASK 52-73-21-400-001).
2 If the fault continues:
_
- do a check and repair the wiring from the indicator light (2WN2) to the indicator light (1WN2) pin A to pin B (Ref. ASM 52-73/01).
3 If the fault continues:
_
- replace the IND LT-SLIDE ARMED, FWD R DOOR (1WN2), (Ref. AMM TASK 52-73-21-000-001) and (Ref. AMM TASK 52-73-21-400-001).
4 If the fault continues:
_
- do a check and repair the wiring from the indicator light (1WV2) to the relay (12WN) pin A to pin A/A2 (Ref. ASM 52-73/01).
5 If the fault continues:
_
- replace the RELAY-PWR SPLY SWITCHOVER (12WN), (Ref. ASM 52-73/01).
6 If the fault continues:
_
- do a check and repair the wiring from the relay (12WN) to the circuit breaker (15WN) pin A/A1 to pin 2 (Ref. ASM 52-73/01).
7 If the fault continues:
_
- replace the C/B-EIS/SLIDES/ARM AND WARN/FLT (15WN), (Ref. ASM 52-73/01).
(2) If the circuit breaker is open:
- close it.
(a) If it opens again:
- replace the indicator light (3WN2) (Ref. AMM 52732100000100) and (Ref. AMM 52732140000100).
1 If the fault continues:
_
- replace the indicator light (2WN2) (Ref. AMM 52732100000100) and (Ref. AMM 52732140000100).

2 If the fault continues:
_
- replace the indicator light (1WN2) (Ref. AMM 52732100000100) and (Ref. AMM 52732140000100).
3 If the fault continues:
_
- replace the relay (12WN) (Ref. ASM 52-73/01). 4 If the fault continues:
_
- Do a check for a short to ground at the wiring from the circuit breaker (15WN) to the indicator light (3WN2) pin 2 to pin A (Ref. ASM 52-73/01).
a If there is a short to ground:
_
- repair the related wiring. b If there is no short to ground:
_
- replace the circuit breaker 15WN.
(b) If the circuit breaker stays closed and the fault continues:
- replace the indicator light (3WN2) (Ref. AMM 52732100000100) and (Ref. AMM 52732140000100).
1 If the fault continues:
_
- replace the indicator light (2WN2) (Ref. AMM 52732100000100) and (Ref. AMM 52732140000100).
2 If the fault continues:
_
- replace the indicator light (1WN2) (Ref. AMM 52732100000100) and (Ref. AMM 52732140000100).
3 If the fault continues:
_
- replace the relay (12WN) (Ref. ASM 52-73/01).
