f If after you disconnected the PRESS SW-G HYD, FLT CTL
_ (10CE2), the current value is less than 400mA:
- replace the PRESS SW-G HYD, FLT CTL (10CE2), (Ref. AMM TASK 27-92-17-000-001) (Ref. AMM TASK 27-92-17-400-001) and connect all the electrical connectors that you disconnected.
g If the current value is more than 400mA:
_ - open the circuit breaker 16CE2,
- connect the electrical connector to these pressure switches:
- PRESS SW-FLT CTL, B (2151GN) (Ref. AMM TASK 29-32-12-400-002),
- PRESS SW-FLT CTL, Y (3151GN) (Ref. AMM TASK 29-32-12-400-003),
- PRESS SW-FLT CTL, G (1151GN) (Ref. AMM TASK 29-32-12-400-001),
- PRESS SW-B HYD, FLT CTL (10CE1) (Ref. AMM TASK 27-92-17-400-003),
- PRESS SW-Y HYD, FLT CTL (10CE3) (Ref. AMM TASK 27-92-17-400-002),
- PRESS SW-G HYD, FLT CTL (10CE2) (Ref. AMM TASK 27-92-17-400-001),
- disconnect the RELAY (48CE) (Ref. IPC 27920803), (Ref. ASM 27-92/02),
- close the circuit breaker 16CE2,
- do a check of the current value: . If the current value is less than 400mA: - open the circuit breaker 16CE2,
- replace the RELAY-ELAC2 EMER SPLY (48CE), (Ref. IPC 27920803)
- close the circuit breaker 16CE2,
- do a check of the current value: . If the current value is more than 400mA: - open the circuit breaker 16CE2,
- disconnect the relay (35CE) (Ref. IPC 27920803).
- close the circuit breaker 16CE2,
- do a check of the current value:
* If the current value is less than 400mA: - open the circuit breaker 16CE2,
- replace the RELAY-ELAC1 BATT SPLY BREAKING (35CE) and install the relay 48CE (Ref. IPC 27920803)
- close the circuit breaker 16CE2,
- do a check of the current value:
* If the current value is more than 400mA: - open the circuit breaker 16CE2,
- replace the RELAY-SEC1 BATT SPLY BREAKING and install the relay (48CE) and relay (35CE) (Ref. IPC 27920803).
2 If the current value stays more than 400mA:
_ - open other circuit breakers (5PB2, 12PB2, 9PB2, 6FP1 and 14XB) one by one while you monitor the current value.
May 01/01R CES
a If the current value suddenly falls below 400mA when you
_ open a circuit breaker:
- do a check of the system related to this circuit breaker to find the cause of this overconsumption.
b If the current value is more than 400mA when all circuit
_
breakers are open
- replace the ELAC-2 (2CE2), (Ref. AMM TASK 27-93-34-000-001) (Ref. AMM TASK 27-93-34-400-001).
(b) If the current is less than 400mA:
- replace the BCL-2 (1PB2), (Ref. AMM TASK 24-38-34-000-001) and (Ref. AMM TASK 24-38-34-400-001).
1 If the fault continues:
_
- replace the BAT-2 (2PB2), (Ref. AMM TASK 24-38-51-000-001) (Ref. AMM TASK 24-38-51-400-001) (Ref. ASM 24-38/02).
R E. Put the aircraft back to the serviceable condition.
(1) In the cockpit, on the ELEC panel 35VU, release the BAT2 pushbutton switch and put a warning notice(s) to tell persons not to operate the battery 2.
(2) In the battery power center 105VU, remove the ammeter between the shunt and ground cable.
(3) Connect the ground cable to the shunt and attach it with the washer and bolt.
(4) In the cockpit, on the ELEC panel 35VU, push the BAT2 pushbutton switch and remove the warning notice(s).
NOTE : After you have isolated the fault, it is necessary to charge
____
the BAT2.
