 B. If the test confirms the fault:
 (1) If the voltage read on the lower ECAM DU is equal to the voltage read on the voltmeter of the ELEC panel 35VU:
 (a) Do the operational test of the BCL (Ref. AMM TASK 24-38-00-710-001).
 1 If the test gives the maintenance message CHECK HOT BUS 2
_
 POWER CONSUMPTION:

 - do the procedure given in (Ref. TASK 24-38-00-810-835).
 2 If the test result is TEST OK:
_
 - do a check and repair the wiring (Ref. AWM 24-38-02) between: . the pin A/a of the BCL2 (1PB2) and the first terminal block, . the pin A/Y of the BCL2 (1PB2) and the first terminal block.

 - do the removal and the restoration of the BAT2 (2PB2) (Ref. AMM TASK 24-38-51-280-001).


 (2) If the voltage read on the lower ECAM DU is different from the voltage read on the voltmeter of the ELEC panel 35VU:
 - replace the BCL-2 (1PB2) (Ref. AMM TASK 24-38-34-000-001) and (Ref. AMM TASK 24-38-34-400-001).
 (a) If the fault continues:
 - replace the P/BSW-ELEC/BAT 2 (7PB2).
 1 If the fault continues:
_
 - do a check of the wiring (Ref. ASM 24-38/02) between: . the pin 2 of the circuit breaker (8PB2) and the pin A/D3 of the ELEC/BAT 2 pushbutton switch (7PB2) . the pin A/D1 of the ELEC/BAT 2 pushbutton switch (7PB2) and the pin A/A of the BCL 2 (1PB2).
 a If the wiring is not correct:
_
 - repair or replace as necessary.
 b If the wiring is correct:
_ - replace the C/B-ELEC/BAT BUS/REF/BCL2 (8PB2).

 May 01/03 CES C. If the test confirms the fault:


 - do a check of the position of the circuit breaker (9PB2).
 (1) If the circuit breaker is closed:

 - do a check for 28VDC at pin 2 of the circuit breaker (9PB2).
 (a) If there is 28VDC:

 - do a check and repair the wiring (Ref. ASM 24-38/02) between: . the pin 2 of the circuit breaker (9PB2) and the pin A/C3 of the ELEC/BAT 2 pushbutton switch (7PB2) . the pin A/C1 of the ELEC/BAT 2 pushbutton switch (7PB2) and the pin A/C of the BCL2 (1PB2).

 (b) If there is no 28VDC:


 - do a check and repair the wiring (Ref. ASM 24-38/02) between: . the pin 1 of the circuit breaker (9PB2) and the 28VDC HOT BUS 704PP.

 (2) If the circuit breaker is open:


 - close it.
 (a) Do a check of the wiring for a short to ground between the pin 2 of the circuit breaker (9PB2) and the pin A/C3 of the ELEC/BAT 2 pushbutton switch (7PB2) (Ref. ASM 24-38/02).
 1_ If the wiring is not correct:
 - repair it.
 2_ If the wiring is correct:

 - replace the C/B-ELEC/BAT REF/BCL2 (9PB2).

 D. Do the test given in para. 3.
