- use a multimeter to do a resistance check across pin 1 and pin 2 of the LOW OIL LEVEL SW (P8).
(a) If the resistance value is < 100 kOhms:
- replace the LOW OIL LEVEL SWITCH (P8) (Ref. AMM TASK 49-93-16-000-003) and (Ref. AMM TASK 49-93-16-400-003).
(b) If the resistance value is > 100 kOhms:
- do a check of the aircraft wiring from the ECB (59KD) AB/H2 to the LOW OIL LEVEL SW (P8) P8/2 and the LOW OIL LEVEL SW (P8) P8/1 to GND (Ref. ASM 49-61/01).
1 If the fault continues:
_
- replace the ECB (59KD) (Ref. AMM TASK 49-61-34-000-003) and (Ref. AMM TASK 49-61-34-400-003).
B. Do the test given in para. 3.
