    LCD Genesis

    Just bought a used 1999 Genesis. Starts good, but just idles along. Push any button the the LCD guage, it resets the guage and whe can go up to 35 mph. After 5 minutes it goes to idle and we push the button again. The guage has condensation inside it so you can only see part of the guage. The forward/reverse on the guage does not work. Any suggestions what the problem is? Thanks

    Is this a fuel injected 1999 Genesis engine, or carburetors?

    I suspect the water damaged MFI is impairing an electrical signal to the engine computer.

    Unplug the MFI display. The electrical connector is in the back, and can be reached from under the front storage hood.

    Find a short piece of #14 household copper wire, extract the Black conductor, and strip 1/2" of the insulation from each end. Shape it into a U form, and push the wire ends into pins 1 (Purple/White) and 3 (Black) of the MFI wiring harness connector.

    This wire loop will bypass the starter security, so you can start the engine.

    See if the engine now starts and runs normally. If so, start shopping for a replacement MFI (part number 3280292).

    When the engine is running properly, you should be able to go a lot faster than 35mph, more like 55mph

    Arrow Virage & Genesis MFI security bypass jumper

    The Polaris MFI display incorporates a security code feature. If the MFI display is Locked, the engine will not crank.

    If you do not know the security code, or the MFI is defective, you can unplug the MFI from the wire harness. This does not allow the engine to crank, until you insert a wire jumper between pins 1 and 3.

    Unplug the MFI display. The electrical connector is in the back, and can be reached from under the front storage hood.

    Find a short piece of #14 household solid copper wire, extract the Black conductor, and strip about 1/2" of the insulation from each end. File or sand any rough ends from the cut wire, so it doesn't damage the connector pins when you push it into the connector.

    Shape it into a U form, and push the wire ends into the holes for pin 1 (Purple/White) and 3 (Black) of the MFI wiring harness connector.

    This wire loop will bypass the starter security, so you can start the engine.

    See if the engine now starts and runs normally.

    Note: Be sure to insert the bypass wire into the correct two pins on the connector.

    It will work on any model with the MFI display.

    All Virage and Genesis models.

    Be sure to insert the bypass wire into the correct two pins on the connector.

    Has anyone had any luck repairing MFI or drying them out? Can you put power to it to see if it does anything mine is blank.
