    My comet won't allow me to start a game. The lights, sounds and flippers all work the start button doesn't work. I installed a remote battery earlier today thinking that would fix the problem but still not able to start a game.

    Try reseating j8 and j10 plugs. Also check switch in trough that it is recognizing a ball present.

    Not sure about the plugs yet but I did check the trough and it's good

    remote holder wires are in the wrong places, red wire needs moved right, black wire needs moved left. does it have credits on it? if it was set to free play, and you pulled batts, its not on free play anymore. if you did coin it up, and it has a credit, can you access your switch test?

    I'll change the wires...
    It wasn't set to free play before I added the remote battery.
    I was told to change out the batteries to a remote battery and I also changed a blown fuse.
    I was trying to get it to FREE PLAY by fixing the above issues, so I'm still stuck.

    can you access the switch test?

    So you suggested I move the wires around and when I did they started smoking on me. The remote battery is ruined.

    Your middle battery looks like it’s installed backwards.

    in the 1st post, the batteries look correct

    Set game for free play, or insert coins.

    When you removed the battery, you erased the setup.

    You probably shouldn’t be giving advice if you’re not familiar how to fix the problem. Just don’t leave a comment unless you’re sure how to fix it. That’s how machines can get damaged.

    Jimmyhonda, I have two WMS Comet. I am 100% familiar with the game operation, repair, and every part of this model, including the program code. I have owned my two for more than 15 years.

    You might consider this next time you offer "advice", Jimmyhonda.

    If cmos/nvram is not storing the setup, then it will start with default setup, showing the game number in diag mode.

    Turning a machine on with or without cmos/nvram will, in no way, damage the machine.

    A short study of the game code will show you an invalid checksum in cmos/nvram will cause a default setup, which is not free play.

    So the start button was previously not working before the battery holder was installed and it wasn’t a free play issue.

    Yes middle battery was installed incorrectly.

    I'm not going to get into my experience of working on pins, professionally, since the early 90s. I'll just bow out and let you handle it from here.

    This is how the remote battery holder should be wired.
