Re: Yanmar 4JH4 TE - Engineeering hours not working
Welcome aboard Springtide.
There have been a few threads about the issue, maybe you can find some help in these.
It is quite possible the original gauge is still recording the hours but failing to display the information i.e. the fault is in the display circuit rather than the recoding circuit.
EDIT: Just realised the above issue was Volvo
related; I'm not sure if your Yanmar engine
hours are a LCD display or not.
