    Question ignition problem

    hi,
    i bought a set of ss comp guages last week and installed them today
    boat is a 87 baja sport 240 merc 454

    problem,when i changed the guages now the boat won't start.
    no spark
    manual says to check for batt volt at + side of the coil.
    i've got 1.2v????
    it says if no voltage check wiring.
    any idea why 1.2 volts??
    there are 2 purple(ign) wires that were connected to old guages.
    1 has 12.5 volts(small connector org,prpl,& blk wires)
    1 comes from the harness (1.2 volts)
    any ideas??
    thanks

    Check to make sure you didn't pull any wires off the ignition switch or maybe blew a fuse. Start with all the easy things first...

    Re: ignition problem

    chaces are you didnt re-install one of the ignition leads.

    should be as follows:
    red into ignition switch
    purple ou to merc harness, and to guages

    maybe you missed a jumper
