    f12x new battery will not start

    Hello everyone. fist post here.
    Just bought a 2002 f12x, got it at a steal.
    Guy said it was running fine but the battery needed to be replaced.
    He bought a walmart battery and now the jetski turns but will not start.
    Battery light comes on and so does the F1 light.
    Any feedback or suggestion other than buying a different battery would help.

    fixed. I kept researching and all it needed was new plugs. 7 blinks/beeps and the battery light flashing. change plugs!

    If the battery light keeps flashing u may need to change the power relay box all the way in the back on top of the pump tunnel.
