Yanmar hour clock

[cloud7]

The hour counter on my Yanmar engine display has stopped displaying any advice appreciated

Is this still the same problem you were asking about last November or the same problem on a new boat ?

I take it the suggestions offered previously were/are no help

You dont say what engine but have you checked that there is a power supply to it when the engine is on. Refer to the wiring diagram to identify the connection. Some just run when the engine is switched on, some ( more recent) however require a pulse from a running engine. Is the tacho working ?

They all do it ..... also Volvo ones.

Various moderately complicated but low cost fixes reported on here, or buy a new one at silly money.

Yes, I'm going to have the same sort of problem because I have a Caterpillar hour meter and a Perkins engine. I'll have to do some research then. (A quick check reveals they work off the alternator. There's a lot of info even a Community Forum)

I had the same problem. This was the solution.

Good luck.

Last thread on this was a couple of weeks ago and I gave the VDO part number required.
