4. Fault Isolation
_______________
A. If the test gives the maintenance message: SEC1 OR WIRING FROM L B ELEV POS XDCR 34CE3
- replace the SEC-1 (1CE1) (Ref. AMM TASK 27-94-34-000-001) and (Ref. AMM TASK 27-94-34-400-001).
(1) If the fault continues:
- do a check and repair the wiring of the POS XDCR COM (ANI 2-1) signal from the SEC 1 (1CE1) to the first terminal block (Ref. ASM 27-94/07).
B. Do the tests given in Para. 3.
Failure of the Left Elevator Position MON Transducer

4. Fault Isolation_______________
R A. If the test gives the maintenance message L ELEV POS MON XDCR OF
R ELAC1/SEC1
R - disconnect and cross the electrical connectors of the elevator position
R transducer unit (49CE1) (Ref. ASM 27-93/07) and do the test given in
R Para. 3.
R NOTE : After the test connect the electrical connectors on their initial____
R plugs.
R (1) If the fault continues:
R - do the trouble shooting procedure (Ref. TASK 31-32-00-810-933)
R related to the ANI 2-X analog input signal of the ELAC COM and SEC
R COM (Ref. ASM 27-93/07) and (Ref. ASM 27-94/07).
R (2) If the test gives the maintenance message L ELEV POS MON XDCR OF
