(a) If the fault continues:
- do a check for a ground signal at the pin A/3 of the engine 1 fire extinguishing bottle 1 (Ref. ASM 26-21/01).
1_ If there is no ground signal:
- repair the above wiring.
2_ If there is a ground signal:
- do a check and repair the wiring of the HP discrete signal
from the engine 1 fire extinguishing bottle 1 to the ENG/APU
FIRE panel (1WD), from pin A/2 to pin A/K (Ref. ASM 26-
21/01).

Not applicable, the fault is evident.
4. Fault Isolation
_______________
A. If the DISCH legend of the ENG 1/AGENT 2 pushbutton switch does not go off:
- disconnect the electrical connector 8WE1-A from the engine 1 fire extinguishing bottle 2
- do a check for continuity between the pins A/2 and A/3 of the engine 1 fire extinguishing bottle 2.
(1) If there is no continuity:
- replace the BOTTLE 2-FIRE EXTING, ENG 1 (8WE1) (Ref. AMM TASK 26-21-41-000-001) and (Ref. AMM TASK 26-21-41-400-001).
(2) If there is continuity:
- connect the electrical connector 8WE1-A on the engine 1 fire extinguishing bottle 2
- replace the ENG/APU FIRE PNL (1WD) (Ref. AMM TASK 26-12-12-000-001) and (Ref. AMM TASK 26-12-12-400-001).
