Doosan (& Daewoo) B20T-5:
INTERMITTENT HYDRAULICS

All hydraulic functions work intermittently. No error codes showing except when truck is turned on message C1 is displayed briefly. No problems with drive function. Pump motor sometimes turns very slowly and then works correctly or not at all. Suspect either a faulty inverter or bearing encoder in pump motor. Identified and replaced one faulty battery cell but intermittent fault is still present.
Any thoughts or anyone experienced similar problem?
Problem was a Faulty lift encoder
