C. Test

ACTION	RESULT
Open the aft right passenger/crew door with the handle of the escape slide in the ARMED position.	Make sure that the SLIDE ARMED white indicator light of the aft right passenger/crew door is not on.

4. Fault Isolation
Subtask 52-13-00-810-050-A

A. If the test confirms the faults:

Do a check of the circuit breaker (13WN) status ASM 527301.

(1) If the circuit breaker is closed:

Do a check for 28VDC at pin A of the indicator light (3WN2) ASM 527301.

(a) If there is 28VDC:

Replace the IND LT-SLIDE ARMED, AFT R DOOR [3WN2] AMM 52-73-21-000-002 and AMM 52-73-21-400-002.

1 If the fault continues:

Do a check for a ground signal at pin C of the proximity switch (17WV2) ASM 315405.

a If there is a ground signal:

Do a check and repair the wiring from the proximity switch (17WN2) to the indicator light (3WN2) : pin B to pin F ASM 315405 and ASM 527301.

b If there is no ground signal:

Repair the wiring from the proximity switch (17WV2) pin C to the ground ASM 315405.

(b) If there is no 28VDC:

Do a check and repair the wiring from the indicator light (3WN2) and the indicator light (2WN2) : pin A to pin B ASM 527301.

1 If the fault continues:

Replace the IND LT-SLIDE ARMED, R EMER EXIT [2WN2] AMM 52-73-21-000-003 and AMM 52-73-21-400-003.

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 ASM 527301.

3 If the fault continues:

Replace the IND LT-SLIDE ARMED, FWD R DOOR [1WN2] AMM 52-73-21-000-001 and AMM 52-73-21-400-001.

4 If the fault continues:

Do a check and repair the wiring from the indicator light (1WN2) to the relay (12WN): pin A to pin A/A2 ASM 527301.

5 If the fault continues:

Replace the RELAY-PWR SPLY SWITCHOVER [12WN] ASM 527301.

6 If the fault continues:

Do a check and repair the wiring from the relay (12WN) to the circuit breaker (13WN) : pin A/A3 to pin 2 ASM 527301.

7 If the fault continues:

Replace the C/B-EIS/SLIDES/ARM AND WARN/GND [13WN] ASM 527301.

(2) If the circuit breaker is open:

Do the procedure (Ref. TSM TASK 24-00-00-810-803).

(a) If the fault continues:

replace the C/B-EIS/SLIDES/ARM AND WARN/GND [13WN] ASM 527301.
