- do a check for 115VAC on the EVMU (Ref. ASM 77-32/02).
(a) If there is 115VAC:
- replace the EVMU (2EV), (Ref. AMM TASK 77-32-34-000-042) and (Ref. AMM TASK 77-32-34-400-042).
(b) If there is no 115VAC:
- do a check and repair the aircraft wiring between the breaker 1EV to the EVMU (2EV) (Ref. ASM 77-32/02).
1 If the fault continues:
_
- replace the C/B-ENGINE/ENG1 AND 2/EVMU (1EV)
C. Do the check given in Para. 3.A.
