  1. Sticky: Tach input is not required for anything, IIRC....

    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...

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

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

    How to cut open a Polaris oval MFD to repair faded digits
  4. Sticky: Apparently MFD 3280307 (1999 SLX, 12-pin Deutsch...

    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...

    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...

    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...
  7. Sticky: What happened with this?

    That would be a 'Fast Trim' MFD just like the Pro models use, correct?

    And it is a 12-pin MFD, correct?

    Perhaps those MFD work differently. I do not have any 12-pin or Fast Trim MFD on hand...

  9. Sticky: It is critical that the buttons be held down...

    It is critical that the buttons be held down firmly and with no wiggling or bouncing during these sequences.

    The MFD must also be awake, of course. It is unclear (to me) whether it matters which...

    Max 250ma output at 14 volts when supply is 9 volts.

    Max input of 14 volts would be an issue since the charging system voltage can get near 15 volts.[/INDENT]


    I do not know how much current...

    Well, I cannot do anything about that.

    It was already known that these MFD could spontaneously reset themselves to zero hours. Now we just know how to do it on demand.
  12. Sticky: MFD LoPR mode threshold testing, characterization

    This particular MFD (and I suspect other variants would be similar) does lots of funky stuff when the voltage sags below 10.9 volts.

    During LoPR warning mode the display alternates every 4-5...
  13. Sticky: How to reset and calibrate MFD voltage display for ACCURATE voltage readings

    After some investigation I determined that a specific voltage is required while resetting the MFD, otherwise the displayed voltage reading will be inaccurate.

    The required voltage on Red/Purple...
  14. Sticky: Polaris oval MFD entering 'sleep mode', then waking up from sleep mode

    Sleep mode occurs at 3 seconds into video.

    Note that the speedometer disappears and the clock appears automatically.

    Also notice that under the clock all the mode labels are visible (RPM CLOCK...
  15. Sticky: Change Polaris MFD display between Metric and US readings (Miles or Kilometers)

    US/Metric mode change

    Use Mode button to cycle through until the display shows VOLT

    While in Volt mode, press and hold SET button for several seconds until m/h changes to km/h or back.

    Both...
  16. Sticky: Reset the Distance Counter (DIST) on Polaris Oval MFD display

    Distance Counter reset (Miles traveled)

    Use Mode button to cycle through until the display shows DIST

    While DIST is displayed, press and hold SET button for 4 seconds, numbers should reset to...
  17. Sticky: How to Reset the Engine Hour counter on the oval Polaris MFD display

    Note: If you have the newer MFI display found on Virage and Genesis watercraft the reset method can be found in this thread.

    This method is experimental (but seems to be working on each MFD...
