External EB9XExternal eb detected 9x times as follow:, ~~~~~ 3507 External EB  9X External eb detected 9x times as follow: 6.41064406460647E+34  3507 Fault can be duplicated in depot. From ER, observed obstacle detection was captured from 0641hrs to 0701hrs intermittently and caused EB in AM and ATPM. From TIMS observed FC740 (obstacle detected). When shake test was carried out on 3507 A/S obstacle detector wire, found resistance high and fluctuating. When remove cable sleeving, found obstacle detector cable broken. Measured coil resistance and contact resistance - Satis. No anomalies and water ingress. Check obstacle detectors were intact are heights were within criteria. No water ingress on Fire Panel. No FC on loss of power. Re-crimped obstacle detector wire & check continuity of wire -Satis. Performed shake test on A and B side obstacle detector wires from underframe, no fluctuations to the resistance. " Justin 45337
