    Power the board down. Check to make sure all the terminal connections are
    tight (particularly the keypads). You should have two black, two red, two
    yellow and two greens all terminated to the appropriate locations listed on
    the board. Drop the keypads and make sure all the wires are hooked up and
    the terminal screws are tight as well.

    After you've done this, power the system back up. Make sure you obtain a
    new 12 volt 5 AH battery (or 7.5 AH if the can's big enough) and connect it
    to the approriate red and black wires.

    Good luck!!!
