Feb 01/98 CES (b) If there is no voltage:
- do a check and repair the wiring (Ref. ASM 33-13/02).
(2) If the integral lighting of several instruments and/or panels is inoperative:
- do a check of the lighting controller fuse related to the defective lighting circuit (Ref. ASM 33-13/02).
(a) If the fuse is correct:
- replace the CONTROLLER-LIGHTING (6LF) (Ref. AMM TASK 33-13-51-000-001) and (Ref. AMM TASK 33-13-51-400-001). (Ref. Fig. 204/TASK 33-13-00-991-002)
1 If the fault continues:
_
- do a check and repair the wiring related to the defective lighting circuit (Ref. ASM 33-13/02).
(b) If the fuse is not correct:
- replace the defective fuse.
(3) If all the integral lighting panels do not operate correctly:
- do a check of the circuit breaker (3LF) status.
(a) If the circuit breaker is closed:
- do a check for 115VAC at pin A/A of the lighting controller (6LF) (Ref. ASM 33-13/02).
1 If there is 115VAC:
_
- replace the CONTROLLER-LIGHTING (6LF) (Ref. AMM TASK 33-13-51-000-001) and (Ref. AMM TASK 33-13-51-400-001).
a If the fault continues:
_
- replace the POT-INT LT/OVHD INTEG LT (7LF) (Ref. IPC 331308).
b If the fault continues:
_
- do a check and repair the wiring between the lighting controller (6LF) and the INT LT/OVHD INTEG LT potentiometer (7LF).
2 If there is no 115VAC:
_
- do a check for a ground signal at pins A/C, B of the lighting controller (6LF) (Ref. ASM 33-13/02).
a If there is no ground signal:
_
- repair the defective wiring between the lighting controller (6LF) pin A/C or A/B and the ground terminal (Ref. ASM 33-13/02).
b If there is a ground signal:
_
- replace the C/B-LIGHTING/INST LT/OVHD/PNL (3LF): . if the fault continues:

Feb 01/98 CES - do a check and repair the wiring between the lighting controller (6LF) pin A/A and the C/B (3LF) (Ref. ASM 33-13/02).
(b) If the circuit breaker is open:
- close the circuit breaker
1_ If the circuit breaker trips:
- replace the CONTROLLER-LIGHTING (6LF) (Ref. AMM TASK 33-13-
51-000-001) and (Ref. AMM TASK 33-13-51-400-001).
a If the fault continues:
_
- do a check for a short to ground at the wiring between the lighting controller (6LF) pin A/A and the C/B (3LF) (Ref. ASM 33-13/01) . if there is a short to ground:
- repair the related wiring. . if there is no short to ground:
- replace the C/B-LIGHTING/INST LT/OVHD/PNL (3LF).
B. Do the test given in Para. 3.
