A. If the test gives the maintenance messages:
L SPLR5 POS XDCR 31CE9
and
R SPLR5 POS XDCR 31CE10
- remove the SEC2 (Ref. AMM TASK 27-94-34-000-001).
(1) At the SEC2 receptacle, do a check of the resistance and of the insulation between the pin AD/10H and the pin AD/10G (15 to 250 ohms) (Ref. ASM 27-94/03).
(a) If the resistance values are in the specified limits:
- 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 less than 15 ohms:
