3. Fault Confirmation
__________________
A. Do the operational test of the Logo Lights (Ref. AMM TASK 33-47-00-710-002).
4. Fault Isolation
_______________
A. If the test shows that the two LOGO LIGHTS 3LY (4LY) do not go off:
- make sure that the NAV LOGO switch 3LA is set to the OFF position.
(1) If the fault continues:
- Open CB 2LR.
(a) If the fault continues:
- replace RELAY 5LY
(Ref. ASM 33-47/01).
(b) If both LOGO LIGHTS 3LY and 4LY go off:
- check and replace if necessary RELAY 6LA and RELAY 7LA (Ref. ASM 33-41/01).
B. Do the test as given in the Para. 3. A.
5. Close-up
________
A. Put the aircraft back to its initial configuration.

Lighting ASM 33-48/01 TSM 33-48-00-810-802 Strobe Lights - One of the Anti-Collision Strobe
Lights does not flash
3. Fault Confirmation
__________________
A. Do the operational test of the Anti-Collision / Strobe Lighting and confirm that none of the strobe lights flash (Ref. AMM TASK 33-48-00-710-002).
4. Fault Isolation
_______________
A. If the test confirms the fault: R - do a check for 115 VAC at the related PWR SPLY UNIT connector A/1, A/2 R and A/3 (Ref. ASM 33-48/01).
R (1) If there is approx. 115 VAC:
- do the trouble shooting procedures for One of the Anti-Collision Strobe Lights does not flash (Ref. TSM TASK 33-48-00-810-802).
R (2) If there is no 115 VAC:
R - do a check for 115 VAC at the PWR SPLY-RELAY 12LV connector A/A1,
R A/B1 and A/C1 (Ref. ASM 33-48/01).
R (a) If there is approx. 115 VAC:
- do a check and repair the wiring between: PWR SPLY-RELAY 12LV conn. A/A1 and related PWR SPLY UNIT conn. A/1,

May 01/04 CES (3) If the fault continues:
PWR SPLY-RELAY 12LV conn. A/B1 and related PWR SPLY UNIT conn.
A/2,
PWR SPLY-RELAY 12LV conn. A/C1 and related PWR SPLY UNIT conn.
A/3,
PWR SPLY-RELAY 12LV conn. A/X1 and LT-STROBE SW 11LV conn. A2,
PWR SPLY-RELAY 12LV conn. A/X2 and LT-STROBE SW 11LV conn. 1A
(Ref. ASM 33-48/01).
R (b) If there is no 115 VAC:
R - do a check for 115 VAC at the PWR SPLY-RELAY 12LV connectors
R A/A2, A/B2 and A/C2 (Ref. ASM 33-48/01).
R 1_ If there is no 115 VAC:
- do a check and repair the wiring between:
CB 10LV conn. A2 and PWR SPLY-RELAY 12LV conn. A/A2,
CB 10LV conn. B2 and PWR SPLY-RELAY 12LV conn. A/B2,
