3. Fault Confirmation
__________________
A. Do the operational test of the Anti-Collision/Strobe Lighting and confirm that the lower anti-collision beacon light does not flash (Ref. AMM TASK 33-48-00-710-001).
4. Fault Isolation
_______________
A. If the test confirms the fault:
- replace the LIGHT-BEACON, LOWER (6LV) (Ref. AMM TASK 33-48-12-000-001) and (Ref. AMM TASK 33-48-12-400-001).
(1) If the fault continues:

- do a check for 200 VAC at the PWR SPLY UNIT (4LV) connectors A/1, A/2 and A/3 (Ref. ASM 33-48/01)
(a) If there is approx. 200 VAC:

- replace the PWR SPLY UNIT-LOWER BEACON (4LV) (Ref. AMM TASK 33-48-37-000-001) and (Ref. AMM TASK 33-48-37-400-001).

(b) If there is no 200 VAC:

- do a check of the PWR SPLY-RELAY (9LV) and replace it if necessary.

(2) If the fault continues:

- do a check of the EXT LT BEACON-SWITCH (2LV) and replace it if necessary.

(3) If the fault continues:

- do a check and repair the wiring between: CB 5LV conn. A2 to PWR SPLY-RELAY 9LV conn. A/A2, CB 5LV conn. B2 to PWR SPLY-RELAY 9LV conn. A/B2, CB 5LV conn. C2 to PWR SPLY-RELAY 9LV conn. A/C2, CB 5LV conn. A2 to EXT LT BEACON-SWITCH 2LV conn. 1B,
