Part of the New Holland Repair Manuals.
New Holland service manual 47500165A covers the WE150B in both 2-piece boom (triple articulate) and monoboom form. It runs from the powershift transmission and axles through swing, travel, the pilot circuit, the main control valve, the cylinders and the cab A/C. It includes three hydraulic schematic frames and 33 electrical frames.
The engine overhaul is in a separate Engine Service Manual. Diagnostic code troubleshooting in the Electrical Systems section gives a cause and a remedy for each code, for example code 7002, low pressure on brake valve, which points to the accumulator charge.
