    Does 1995 mdf have any power when not cranked up?

    Just installed and rigged up replacement mdf on 1995 polaris slt 750. It doesnt have anything displayed or will not display anything. Is this normal when not cranked and does it only power up when cranked? Everyone is asleep, so can't crank it, and didnt want to open cpu if that's normal

    Should always be powered up when the battery is connected.

    The MFD does have a small fuse inside the electrical box. If it has blown the fuse, only replace with another 1/4 Amp fuse, nothing rated higher.

    If you have not yet done so, disconnected the battery negative and then open and inspect inside the electrical box. Should be zero moisture and clean inside. It is normal for the terminal board to be smeared with clear dielectric grease.

    If you have a bilge pump then there will be a second, 3 Amp, stubby fuse for the bilge pump.

    Note: Be very sure you have the battery Polaris correct, negative to engine ground. These machines do not like reversed battery polarity, not even for a moment.

    Thanks all, OK, to get into cdi box, I unplug neg on battery and then Unscrew the six screws on the side, and I guess the 6 screws on the bottom where the wires come in? I couldnt find anywhere on how to open.

    I'd go out and push mode to wake it up before opening the box.

    I'd also unplug mfd when reconnecting negative battery cable. If you bounce the neg cable it can fry an mfd
