Sumitomo HA-60C 1997 main travel defect
Good day! We have a problem with travel at Sumitomo HA-60C 1997.
The emergency travel - working correct, the pumps and other hydraulics - normal.
But main travel handle adjusting potentiometeres are ok and singnal comes to mainboard but travel and turn not working.
Could you help me with it defect? Or maybe you have electric schematics?
