    MFD Quit Working

    I have a 1999 Polaris slth jets ski and the mfd has quit working and I have unplugged it and plug in again but the only thing that comes on a steady red light in the top middle. Any suggestion on whats going on or how to fix it?

    There is a fuse inside the electrical box that might be blown... that will shut the MFD down completely. Is there anything working on it or is it completely off?

    And / or the connections at the terminals in and out of the fuse on terminal board might be corroded.
    Removing the terminals and cleaning up the connections might resolve your issue as it did for me on
    a 98 SLXH, same exact issue the red LED was working but not display.
