Do the -2's have a pvc controller? The -3s had a pump controller that always goes out on them
Not sure, I need to know the wiring diagrahm for the # 7 fuse VAL.c/u keep blowing a 1 amp fuse. I have already replaced the computer.
I narrowed down the problem with the ex120-2 cutting out when hot. It was the displacement solenoid valve, The electrical coil was crack and that was because the two oil seals behind the coil leaked and would slowly preasurize the electrical coil and expand it, then cutting out the coil circuit ( the coil is 18 ohms resistance) then the excavator would start to cut out. I fixed the seals and now its OK, but I would still like to replace the coil or solenoid. Does anyone have one ?

Hi. Do you still have any manuals for an EX120-2 ?
We have just bought one at auction and needs a few things doing.
Would appreciate any documentation for this machine. Operator's, service, parts, technical manuals, wiring diagrams etc.

Sounds like the N sensor is not working, Check wiring to sensor on top of pump also known as the rpm sensor. Looks like a button held in with one bolt.
