(2) If the fault continues:
- do a check for 115VAC at pin AC/2 of the DMC3 (1WT3) (Ref. ASM 31-61/02).
(a) If there is 115VAC:
- 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 115VAC:
- do a check for a ground signal at pin AC/7 of the DMC3 (1WT3).
1 If there is no ground signal:
_
- repair the wiring from DMC3 (1WT3) pin AC/7 to the ground terminal.
2 If there is a ground signal:
_ - replace the RELAY-BUS1 TO ESS BUS SWTG, DMC3 (26WT).
a If the fault continues:
_
- replace the C/B-EIS/DMC3/SPLY (10WT3). . If the fault continues:
* do a check of the wiring from the DMC3 BUS1 TO ESS BUS SWTG relay (26WT): pin A2 to DMC3 (1WT3) pin AC/2
