 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:
 - replace the GEN-APU (8XS) (Ref. AMM TASK 24-23-51-000-001) and (Ref. AMM TASK 24-23-51-400-001).
 C. 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 (23XS).
 (a) If the circuit breaker (23XS) is open:
 - close it.
 1 If the circuit breaker trips:
_
 - do a check for a short to ground between the circuit breaker APU GEN/EGIU2/115VAC (23XS) and the pin AB/1D of the EGIU2 (22XU2) (Ref. ASM 24-23/01),

 - if there is a short to ground: .repair the wiring,

 - if there is no short to ground: .replace the C/B APU GEN/EGIU2/115VAC (23XS).
