    MFD questions

    So my MFD is not functioning, i check the fuse and its fine theres power to the plug. I when ahead and open it up and clean the LCD screen connector, now that is clean how heck do i reconnect it to the LCD screen?? I see a sponge with a "what looks like" magnet strip that goes on the connection. but Is there a glue that they use to keep it place or do i just place it on there and screw it on??

    The LCD display uses a special conductive rubber strip to provide the electrical link between the LCD and the circuit board.

    The surfaces of the rubber strip must be very clean, and of course the mating surfaces on the LCD and circuit board.

    The conductive rubber strip simply touches both the LCD and circuit board, and no glue or anything else (not even fingerprints) should be in there.

    At the most, you can wipe the surfaces of the rubber strip with a lint free clean cloth. Then just re-assemble the oval MFD unit.

    Alright, after some heavy duty scrubbing on the Metal conductor and gentely cleaning the sponge connector put it back together, jury rig the power to a 12 V battery (20 gauge wire 8-22 gauge butt splice to pins 1 and 2 lower right quadrant.) and it works like a CHARM!!! Heres a picture on how to power/test MFD without installing it to a jet ski.

    Good idea using the butt splice connectors to avoid possible shorting between the pins.

    Note to others that when using separate wires for power; you must make sure you get the positive and negative onto the correct pins. Get it backwards and the MFD can be toasted.
