A. Do the operational test of the FWD and AFT Cargo-Compartment Lighting (Ref. AMM TASK 33-34-00-710-001).
4. Fault Isolation
_______________
A. If the operational test shows that no lights in the FWD Cargo Compartment come on:
- replace a fluorescent tube.
(1) If the fluorescent tube comes on:
- replace all the fluorescent tubes.
(2) If the fault continues:
- do a check for 115 VDC at the related BALLAST UNIT connector A/C (Ref. ASM 33-34/01).
(a) If there is approx. 115 VAC:
- replace the related BALLAST UNIT (Ref. AMM TASK 33-34-11-000-001) and (Ref. AMM TASK 33-34-11-400-001).
(b) If there is no 115 VAC:
- do a check of the FWD CARGO COMPT SW 6LU and replace it if necessary.
