Our Sumitomo SH120-2 has an electrical fault that no one can fix. It randomly starts beeping and flashing up all different faults on the screen from low oil,low battery, chinese, any thing that you can think of and then the machine starts jerking, walking off one way and eventually locks up and it has to be put into backup mode to proceed working. It had a new computer put in and tried. I think that was actually worse. Its had Sumitomo technicians spend heaps of time on it and no one can get this thing sorted. Its had various sensors replaced and the ignition checked. Sometimes it can go fro 2 days without beeping and sometimes it can start beeping as soon as it starts up. Does anyone have any idea what could be causing this digger to do this? Thanks Cam
