a_ If the circuit breaker trips again:
- do a check for a short to ground and repair the wiring
from the circuit breaker (5WW) to the loud speaker (7WW)
(Ref. ASM 31-51/01).
C. If the fault only causes inhibition of the audio signal related to the CVR or TCAS
- replace the LOUD SPEAKER-F/O (8WW) (Ref. AMM TASK 31-53-21-000-001) and (Ref. AMM TASK 31-53-21-400-001).
(1) If the fault continues:
- do a check and repair the wiring of pins A/R and A/S from the loud speaker (8WW) to the audio mixing box (15WW) pins G, H (Ref. ASM 31-52/04).
D. If the fault only causes inhibition of the aural warnings related to the GPWS:
- replace the LOUD SPEAKER-F/O (8WW) (Ref. AMM TASK 31-53-21-000-001) and (Ref. AMM TASK 31-53-21-400-001).
(1) If the fault continues:
- do a check and repair the wiring of pins A/K and A/L from the loud speaker (8WW) to the first terminal block (Ref. ASM 31-52/04).
E. Do the test given in Para. 3.
