CES
(2) At the SEC2 receptacle, do a check of the resistance between the pin AB/9E and the pin AB/9F (Ref. ASM 27-94/08):
(a) If the resistance value is less than 10 Ohms:
1 Do this procedure (Ref. TASK 27-90-00-810-801).
_ 2 Replace the ELAC-2 (2CE2) (Ref. AMM TASK 27-93-34-000-001) and
_
(Ref. AMM TASK 27-93-34-400-001).
3 Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and
_
(Ref. AMM TASK 27-94-34-400-001).
(b) If the resistance is more than 10 Ohms: 1 Replace the SEC-2 (1CE2) (Ref. AMM TASK 27-94-34-000-001) and
_ (Ref. AMM TASK 27-94-34-400-001). Install the ELAC2 (Ref. AMM TASK 27-93-34-400-001).
2 If the fault continues:
_ a Do a check of the wiring of the ACS1 SPLY XDCR signal from
_ the SEC2 MON side to the COM side, pins AE/10D and AE/10E to pins AB/8E and AB/8F (Ref. ASM 27-94/08).
- if the wiring is correct, go to Para. b_
- if the wiring is not correct, repair the above wiring. b Do a check and repair the wiring of the ACS1 SPLY XDCR
_ signal from the SEC2 COM side to the first terminal block, pins AB/9E and AB/9F (Ref. ASM 27-94/08).
B. Do the test given in para. 3.
