TASK 29-12-00-810-813
FAULT Light of the BLUE ELEC PUMP P/BSW is ON
1. Possible Causes
- BOARD-ANN LT TEST & INTFC (11LP)
- wiring
2. Job Set-up Information
A. Referenced Information
REFERENCE DESIGNATION
AMM 24-41-00-861-002 Energize the Aircraft Electrical Circuits from the External Power
AMM 24-41-00-862-002 De-energize the Aircraft Electrical Circuits Supplied from the External Power
AMM 33-14-00-710-001 Operational Test of the Lights
AMM 33-14-33-000-001 Removal of the Annunciator-Light Test and Interface-Board (1LP, 2LP, 3LP, 4LP, 5LP, 6LP, 7LP, 8LP, 9LP, 10LP, 11LP, 12LP, 18LP, 19LP, 20LP)
AMM 33-14-33-400-001 Installation of the Annunciator-Light Test and Interface-Board (1LP, 2LP, 3LP, 4LP, 5LP, 6LP, 7LP, 8LP, 9LP, 10LP, 11LP, 12LP, 18LP, 19LP, 20LP)
ASM 33-14/18
3. Fault Confirmation
A. Aircraft Maintenance Configuration
(1) Energize the aircraft electrical circuits AMM TASK 24-41-00-861-002 .
(2) On the overhead panel 40VU, look for the FAULT light of the BLUE ELEC PUMP P/BSW.
4. Fault Isolation
A. If the Fault Confirmation gives:
- the BLUE ELEC PUMP P/BSW FAULT on panel 40VU:
- replace the BOARD-ANN LT TEST & INTFC (11LP)
AMM TASK 33-14-33-000-001 and AMM TASK 33-14-33-400-001 .
(1) If the fault continues:
- do a check and repair the wiring between the:
BOARD-ANN LT TEST & INTFC (11LP) pin A/10 and the P/BSW-HYD/BLUE/ELEC PUMP (2704GJ) pin A/7 ASM 33-14/18 .
B. Do the operational test of the annunciator light test system AMM TASK 33-14-00-710-001 to make sure that the operation is correct.
5. Close-up
A. De-energize the aircraft electrical circuits AMM TASK 24-41-00-862-002 . |
