How to Reset the Engine Hour counter on the oval Polaris MFD display

[K447]

Never had the time to mess with it.

Did you figure out anything with the MSX displays?

Bring the 12-pin display(s) to the gathering, even if that watercraft does not come along.

No new info on the MSX displays. I have not tried anything new with them recently. I suspect the NGI display was developed by a different group and they were unaware of, or did not care about, the 'hidden' features of the previous display types.

I only have the 8 pin 3280264 which should work like the other 8 pin MFDs you have tested. Dave has a 12 pin in one of his skis.

I have a 99 SLX that has the 12 pin, it will be at the gathering, in a ski, no issues removing it to do some testing though.

Not so much a 12-pin question, more about whether the fast trim version(s) respond to the reset methods in the same manner as the regular trim speed MFD.

I did not check, but I think all the 12-pin MFD were fast trim versions. Is this correct?

I am not positive if all 12 pin version are fast trim, but my 1999 SLX has fast trim. I have both the 12 pin and 8 pin, both with fast trim.

I did try the Hour reset procedure you described above on my 1999 SLX to no avail.

It would not enter calibration mode...

Apparently MFD 3280307 (1999 SLX, 12-pin Deutsch connector) does not respond to the same button press methods as the other MFD models. I do not know if there is a different method of triggering Calibration or Engine Hour reset modes on this MFD model.

MFD 3280307 has curved graphical fuel and oil level indicator bars.
This 12-pin MFD apparently also used on the 1999 and 2000 Pro 785 and 2000 SLX, but not the Pro 1200.

So somehow I was replacing my battery and tinkering with things in my 04 virage and my hours went from 120.xx to 553.5 not sure how this happen but it's really worrying me

K447 Do you have info on how to fix faded digits?

See this thread;

[K447]

When resetting the hours do you have to set the RPMs at 1200? How do you accomplish this on the bench?

Tachometer input is not required, per the info in post #1.

Were you able to watch the video for resetting engine hour counter?

[n-mod]

Yes I did, I was just confused about the next part. So it's only required if I want to reset the distance?

Tach input is not required for anything, IIRC. Just that IF there is tach input, the display acts a little different.

It has been a few years since I did the research, built the MFD testing/calibration rig and posted the videos. Am I forgetting something?

Distance Reset is a normal MFD function, as outlined on this page of the Polaris instructions.
