IPC 333508 AMM 33-35-00-720-001 Functional Test of the Avionics-Compartment Lighting ASM 33-35/01
3. Fault Confirmation
__________________
A. Test Do the functional test of the equipment compartment lighting (Ref. AMM TASK 33-35-00-720-001).
4. Fault Isolation
_______________
A. If during the functional test when you push the AVIONICS COMPT LT pushbutton-switch (23LS) the aft-left lateral dome-light in the avionics compartment does not operate correctly:
- remove the P/BSW-AVIONICS COMPT LT (23LS) (Ref. IPC 333508).
(1) If the fault continues:
- remove the RELAY-PWR SPLY, AVIONICS COMPT AFT L LT CTL (24LS) (Ref. IPC 333508).
(a) If the fault continues:
- do a check and repair the wiring between the pushbutton switch (23LS) pin A/C2 and the pin A/X1 of the power supply relay (24LS) (Ref. ASM 33-35/01).
B. Do the test given in Para. 3.
