**ON A/C 001-003, 051-052,
B. If the operational test gives the maintenance message:
EPSU EXT LOAD FWD L:
- do the operational test of the emergency lights not with CIDS (Ref. AMM TASK 33-51-00-710-006).
(1) If the green LED 'OK EXTERNAL LOADS' comes on:
- replace the POWER SUPPLY UNIT-EMERGENCY (10WL) (Ref. AMM TASK 33-51-38-000-001) and (Ref. AMM TASK 33-51-38-400-001).
(2) If the red LED 'FAULT EXTERNAL LOADS' comes on and a correct adapter cable between the escape slide and the aircraft electrical connector is available:
NOTE : A fault in one of the two forward escape slides can cause the
____
LED to come on.
NOTE : For tests, use one of the items of equipment that follows:
____
- A connector with four lamps (6V, 0.2 amps) in parallel
- A connector with a 7.5 ohm, 5 watt resistor
- A serviceable escape slide.

(a) Do the subsequent procedures:
- remove the ESCAPE SLIDE FWD L (7500MM) as necessary to get access to the electrical connector (Ref. AMM TASK 25-62-44-000-002).
- connect a serviceable escape slide with the adapter cable to the aircraft.
(b) If the fault does no longer exist:
- remove the old ESCAPE SLIDE FWD L (7500MM) fully (Ref. AMM TASK 25-62-44-000-002).
- install the serviceable escape slide (Ref. AMM TASK 25-62-44-400-001).
(c) If the fault continues:
- connect the ESCAPE SLIDE FWD L (7500MM) electrically only.
- remove the ESCAPE SLIDE FWD R (7501MM) as necessary to get access to the electrical connector (Ref. AMM TASK 25-62-44-000-002).
- connect a serviceable escape slide with the adapter cable to the aircraft.
(d) If the fault does no longer exist:
- remove the old ESCAPE SLIDE FWD R (7501MM) fully (Ref. AMM TASK 25-62-44-000-002).
- install the serviceable escape slide (Ref. AMM TASK 25-62-44-400-001).
- install the old ESCAPE SLIDE FWD L (7500MM) (Ref. AMM TASK 25-62-44-000-001).
(e) If the fault continues:
- do a check and repair the wiring between: escape slide connector 2870VC pin A and EPSU (10WL) pin F, escape slide connector 2870VC pin B and GND, PROX SW-HANDLE, R FWD ESC SLIDE (4WN2) pin E and EPSU (10WL) pin S, PROX SW-HANDLE, R FWD ESC SLIDE (4WN2) pin F and GND, PROX SW-HANDLE, R FWD PAX/CREW DOOR (13WV2) pin E and EPSU (10WL) pin <K, PROX SW-HANDLE, R FWD PAX/CREW DOOR (13WV2) pin F and GND (Ref. ASM 33-51/01) and (Ref. AWM 33-51-04).
(f) If the fault does no longer exist:
- install the old ESCAPE SLIDE FWD R (7501MM) (Ref. AMM TASK 25-62-44-400-001).
- install the old ESCAPE SLIDE FWD L (7500MM) (Ref. AMM TASK 25-62-44-000-001).
(g) If the fault continues:
- do a check and repair the wiring between: escape slide connector 2871VC pin A and EPSU (10WL) pin T, escape slide connector 2871VC pin B and GND,
