- close the circuit breaker (3WZ).
(a) If this circuit breaker stays closed:
- install the GPWC (Ref. AMM TASK 34-48-34-400-001)
1 If the circuit breaker trips again:
_
- replace the GPWC (Ref. AMM TASK 34-48-34-000-001) and (Ref. AMM TASK 34-48-34-400-001).
(b) If this circuit breaker trips again:
- do a check for a short to ground at the wiring between the circuit breaker (3WZ) and the GPWC (1WZ) (Ref. ASM 34-48/01).
1 If there is a short to ground:
_ - repair the above wiring.
2 If there is no short to ground:
_
- replace the C/B-EIS/GPWS/115VAC (3WZ).
3 Install the GPWC
_ (Ref. AMM TASK 34-48-34-400-001).
D. Do the test given in Para. 3.B.
