Has anyone figured out how to set an hour meter?

Saw earlier threads discussing this but not really a conclusion.
In 2003 the hours meter is on the tach gauge. When you change the gauge (due to nonworking rpm dial) the new hour meter will show "0.0" even though the hours are stored in the engine's ecm. The gauge is digital, not analog, meaning all the gauges on the dash use identical plugs coming from the mcd and needs to see 600rpm from the motor to count time.
With older, analog gauges you can just put 12v to the gauge on a workbench and have it start counting.

So, has anyone figured out a way to do this yet with the digital gauge? Is there a way to trick the gauge into thinking it's attached to a running motor or otherwise input the desired hours?

Oh yes, i think there were posts about square wave generators and more magic. You may have to dig deep to find what you are looking for. The dealer can get you the correct hours from the ecm. If you have perfect pass from when the boat was new, it will have the hours also. Unless you blew a fuse and it stopped working. Regardless, you can monitor your hours per year with PP if equipped.

He needs to add hours to his new meter, so he would need to run it in forward. WOT would be even better.

But seriously, if I had the gauge, I could figure it out. The tachometer uses the exact same plug as the other gauges?

Clip one wire that leads to the meter? I dunno, I am not about to do that, but seems legit.

Contact medallion, maybe they can help you out. My dealer was not any help on mine, I just used the PP hour meter.

I have the schematic and instructions saved from a post a couple of years ago to advance the meter but won't be home until later this evening (Wednesday)

Simple to build...
