B. If there is no CFDS maintenance message, but one light does not come on:
- replace the related FLUORESCENT TUBE (Ref. AMM TASK 33-21-11-000-001) and (Ref. AMM TASK 33-21-11-400-001).
(1) If the fault continues:
- do a check for 115 VAC at the related BALLAST UNIT connector A/C (Ref. ASM 33-21/01), (Ref. ASM 33-21/02) and (Ref. ASM 33-21/03).
(a) If there is approx. 115 VAC:
- replace the related BALLAST UNIT-LAMP (Ref. AMM TASK 33-21-11-000-001) and (Ref. AMM TASK 33-21-11-400-001).
(b) If there is no 115 VAC:
- do a check and repair the wiring if necessary between the related: BALLAST UNIT connector A/C and its CB, BALLAST UNIT connector A/A and GND, BALLAST UNIT connector A/B and GND (Ref. ASM 33-21/01), (Ref. ASM 33-21/02) and (Ref. ASM 33-21/03).
(2) If the fault continues:
- replace the related DEU-A (Ref. AMM TASK 23-73-46-000-001) and (Ref. AMM TASK 23-73-46-400-001).
(3) If the fault continues:
- do a check and repair the wiring between the related: BALLAST UNIT connector A/D and DEU-A connector B/1,B/4,B/9 or B/12, BALLAST UNIT connector A/E and DEU-A connector B/2,B/5,B/10 or B/13, BALLAST UNIT connector A/F and DEU-A connector B/3,B/6,B/11 or B/14 (Ref. ASM 33-21/01), (Ref. ASM 33-21/02) and (Ref. ASM 33-21/03).
