A. Aircraft Maintenance Configuration
(1) Disarm the percussion system of the door damper and emergency operation cylinder (Ref. AMM TASK 52-10-00-860-001).
(2) Remove the escape slide or escape slide/raft pack assembbly (Ref. AMM TASK 25-62-44-000-002).

4. Fault Isolation
_______________
A. If the test confirms the fault:
- do a check of the circuit breaker (13WN) 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 (3WN1) (Ref. ASM 52-73/01).
(a) If there is 28VDC:
- replace the IND LT-SLIDE ARMED, AFT L DOOR (3WN1) (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 (17WV1) (Ref. ASM 31-54/05).
a If there is a ground signal:
_
- do a check and repair the wiring from the proximity switch (17WV1) to the indicator light (3WN1): 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 (17WV1) pin C to the ground (Ref. ASM 31-54/05).

CES (b) If there is no 28VDC:
- do a check and repair the wiring from the indicator light
(3WN1) and the indicator light (2WN1): 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, L EMER EXIT (2WN1) (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 (2WN1) to the indicator light (1WN1): pin A to pin B (Ref. ASM 52-73/01).
3 If the fault continues:
_
- replace the IND LT-SLIDE ARMED, FWD L DOOR (1WN1) (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 (1WN1) to the relay (12WN): pin A to pin A/B2 (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 (13WN): pin A/B3 to pin 2 (Ref. ASM 52-73/01).
7 If the fault continues:
_
- replace the C/B-EIS/SLIDES/ARM AND WARN/GND (13WN) (Ref. ASM 52-73/01).
(2) If the circuit breaker is open:
- close the circuit breaker.
(a) If the circuit breaker trips:
- replace the indicator light (3WN1) (Ref. AMM TASK 52-73-21-000-001) and (Ref. AMM TASK 52-73-21-400-001).
1 If the fault continues:
_
- replace the indicator light (2WN1) (Ref. AMM TASK 52-73-21-000-001) and (Ref. AMM TASK 52-73-21-400-001).
2 If the fault continues:
_
- replace the indicator light (1WN1) (Ref. AMM TASK 52-73-21-000-001) and (Ref. AMM TASK 52-73-21-400-001).
