4. Fault Isolation
_______________
A. If the BITE test gives the maintenance message: L SPLR 1 SERVO VLV 31CE1 OR OUTPUT FROM SEC 3
- replace the SEC-3 (1CE3), (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(1) If the fault continues:
- replace the servo valve of the servo control (31CE1), (Ref. AMM TASK 27-64-51-000-001) and (Ref. AMM TASK 27-64-51-400-001).
NOTE : The resistance must be 500 ohms +/- 10 %.
____
(2) If the fault continues:
- do a check and repair the wiring of the SV signal from the servo control (31CE1) to the SEC 3 (1CE3), (Ref. ASM 27-94/04).
B. Do the test given in Para. 3.
