B. If the test confirms the fault:
- replace the EGIU-2 (22XU2) (Ref. AMM TASK 24-22-33-000-001) and (Ref. AMM TASK 24-22-33-400-002).
(1) If the fault continues:
- do a check of the position of the circuit breaker (23XU2).
(a) If the circuit breaker (23XU2) is open:
- close it.
1 If the circuit breaker trips:
_
- do a check for a short to ground between the pin 2 of the circuit breaker GEN2/EGIU2/115VAC (23XU2) and the pin AA/15D of the EGIU2 (22XU2) (Ref. ASM 24-22/01),
- if there is a short to ground: . repair the wiring,
- if there is no short to ground: . replace the C/B-GEN2/EGIU2/115VAC (23XU2).
