B. If the fault symptom is identified by the maintenance message: REG-PRESS XDCR 8HA1
-do a check of the status of the circuit breaker (2HA1)
(1) If the circuit breaker is closed
-do a check for 28VDC at pin A/1 of the bleed regulated-pressure transducer (8HA1) (Ref. ASM 36-11/01).
(a) If there is no 28VDC
-do a check of the wiring between pin A/1 of the bleed regulated-pressure transducer (8HA1) and the circuit breaker (2HA1).
1 If there is no continuity:
_ -repair the above wiring.
2 If there is continuity:
_ -replace the circuit breaker (2HA1).
(b) If there is 28VDC
-do a check for ground at pin A/2 of the bleed regulated-pressure transducer (8HA1).
1 If there is no ground signal:
_
-repair the wiring between pin A/2 of the bleed regulated-pressure transducer (8HA1) and the ground terminal.
2 If there is a ground signal:
_
-replace the XDCR-BLEED REGULATED PRESS, ENG 1 (8HA1) (Ref. AMM TASK 36-11-16-000-001) and (Ref. AMM TASK 36-11-16-400-001).
a If the fault continues:
_
-do a check and repair the wiring from the bleed regulated-pressure transducer (8HA1) pins A/3 and A/4 to the BMC1 (1HA1) pins AA/12B and AA/11B (Ref. ASM 36-11/01)
(2) If the circuit breaker is open
-close the circuit breaker.
(a) If the circuit breaker trips
-replace the BMC-1 (1HA1) (Ref. AMM TASK 36-11-34-000-001) and (Ref. AMM TASK 36-11-34-400-001).
1_ If the fault continues:
- do a check for short to ground on the wiring from pin A/1 of
the bleed regulated-pressure transducer (8HA1) to the
circuit breaker (2HA1).
