g If the current value is more than 400mA:
_ - open the circuit breaker 16CE1,
- 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 (35CE) (Ref. IPC 27920803) (Ref. ASM 27-92/02),
- close the circuit breaker 16CE1.
2 If the current value stays more than 400mA:
_ - open other circuit breakers (5PB1, 12PB1, 9PB1, 7XE and 22CE) one by one while you monitor the current value.
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-1 (2CE1), (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-1 (1PB1), (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-1 (2PB1), (Ref. AMM TASK 24-38-51-000-001) (Ref. AMM TASK 24-38-51-400-001).
R E. Put the aircraft back to the serviceable condition.
(1) In the cockpit, on the ELEC panel 35VU, release the BAT1 pushbutton switch and put a warning notice(s) to tell persons not to operate the battery 1.

(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 BAT1 pushbutton switch and remove the warning notice(s).
NOTE : After you have isolated the fault, it is necessary to charge
____
the battery 1
(5) Energize the aircraft electrical circuits
(Ref. AMM TASK 24-41-00-861-002).
R F. Do the test given in para. 3.

- do a check for a ground signal at pin A/Y of the BCL1 (2) (Ref. ASM 24-38/01).
(1) If there is no ground signal:
- replace the RELAY-BUS 1XP CTL (15XC).
(a) If the fault continues:
- replace the RELAY-BUS 2XP CTL (16XC).
1 If the fault continues:
_
- do a check and repair the wiring between: . pin A2 of BUS 2XP control relay (16XC) and the ground, . pin A3 of BUS 2XP control relay (16XC) and pin A2 of BUS 1XP control relay (15XC), . pin A3 of BUS 1XP control relay (15XC) and pin A/Y of the BCL1 (2).
