Part of the Yanmar Operator Manuals.
A YD25 panel that powers up blank, or chirps an alarm you cannot decode, stops an engine as surely as a dead battery, and every hour spent guessing at the harness is an hour the engine sits. This 20 page Yanmar YD25 Operation Manual (publication 164100-29010) is the factory document for the YD25 instrument panel used with Yanmar JH and 4LV engine models.
Inside you get the System Setup routine for selecting the engine model and power link mode, the Operation pages for starting, stopping, and cycling through the engine monitoring screens, and a Main Menu chapter covering active alarms, active errors, error codes (DTC), and display settings.
The back of the book carries the working data: technical specifications including the 8 to 16 VDC supply range, dimensional drawings, and harness installation instructions down to the 3A accessory fuse and mating connector. Download the PDF, wire the panel right, and get the engine running again.
