* repair the wiring which has no continuity.
(3) If the fault continues:
- do a check for 28VDC at pin AC/3 of the DMC3 (1WT3) (Ref. ASM 31-61/02).
(a) If there is 28VDC:
- replace the DMC-3 (1WT3) (Ref. AMM TASK 31-63-34-000-001) and (Ref. AMM TASK 31-63-34-400-001).
(b) If there is no 28VDC:
- do a check for a ground signal at pin AC/11 of the DMC3 (1WT3) (Ref. ASM 31-61/02).
1_ If there is no ground signal:
- repair the wiring from DMC3 (1WT3) pin AC/11 to the ground
terminal.
2 If there is a ground signal:
_
- do a check of the wiring from DMC3 (1WT3) pin AC/3 to the circuit breaker (21WT3) (Ref. ASM 31-61/02).
a If there is no continuity:
_
- repair the wiring. b If there is continuity:
_ - replace the C/B-EIS/DMC3/SWTG (21WT3).
(4) If the fault continues:
- do a check for a ground signal at pin AB/8H, 4C of the DMC1 (1WT1).
(a) If there is no ground signal:
- do a check for a ground signal at pin AA/2 of the EIS DMC selector switch (18WT) (Ref. ASM 31-68/02).
1 If there is no ground signal:
_
- replace the SEL SW-EIS DMC (18WT). 2 If there is a ground signal:
_
- do a check of the wiring from EIS DMC selector switch (18WT) pin 2 to DMC1 (1WT1) pin AB/8H, 4C.
a If there is no continuity:
_
- repair the wiring. b If there is continuity:
_
- replace the DMC-1 (1WT1) (Ref. AMM TASK 31-63-34-000-001) (Ref. AMM TASK 31-63-34-400-001).
