3. Fault Confirmation
__________________
A. Do the operational test of the Anti-Collision/Strobe Lighting and confirm that one of the strobe lights does not flash (Ref. AMM TASK 33-48-00-710-002).
4. Fault Isolation
_______________
A. If the test confirms the fault in the LH WING TIP STROBE:
- replace the LIGHT-STROBE, L WING TIP 17LV (Ref. AMM TASK 33-48-14-000-001) and (Ref. AMM TASK 33-48-14-400-001).
(1) If the fault continues:
- replace the PWR SPLY UNIT-L WING TIP STROBE LIGHT 631 (15LV) (Ref. AMM TASK 33-48-38-000-001) and (Ref. AMM TASK 33-48-38-400-001).
(2) If the fault continues:
- do a check of the PWR SPLY-RELAY 12LV and replace it if necessary.
