The digital display for my
Yanmar 4JH57 doesn't
work. Its unreadable and the two buttons below it don't seem to do anything. Strangely at night you can just barley read it. It seems to say F3-180 which is where you select the
fuel level gauge setting. Again the buttons below the display don't seem
work, so there is no way to get it out of that mode.
Any ideas how to fix this?
