 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 the indicator light (1WV1) pin A (Ref. ASM 52-73/01).
 (a) If there is 28VDC:
 - 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).
 1 If the fault continues:
_
 - do a check for a ground signal at pin C of the proximity switch (13WN1) (Ref. ASM 31-54/05).
 a If there is a ground signal:
_
 - do a check and repair the wiring from the proximity switch (13WV1) to the indicator light (1WN1) 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 (13WV1) pin C to the ground, (Ref. ASM 31-54/05).
 (b) If there is no 28VDC:
 - do a check for 28VDC at pin A/B1 of the relay (12WN) (Ref. ASM 52-73/01).

 1_ If there is 28VDC:
 - replace the RELAY-PWR SPLY SWITCHOVER (12WN), (Ref. ASM 52-
73/01).

 a If the fault continues:
_
 - do a check and repair the wiring from the relay (12WN) to the indicator light (1WN1) pin A/B2 to pin A (Ref. ASM 52-73/01).
 2 If there is no 28VDC:
_
 - do a check of the wiring from the circuit breaker (15WN) to the relay (12WN), pin 2 to A/B1.
 a If there is continuity:
_
 - replace the C/B-EIS/SLIDES/ARM AND WARN/FLT (15WN), (Ref. ASM 52-73/01).
 b If there is no continuity:
_
 - repair the wiring from the circuit breaker (15WN) to the relay (12WN) pin 2 to pin A/B1 (Ref. ASM 52-73/01).
