    Anyone know where the braided ground coming from the body hooks up in the back box? Thanks

    #2 1 year ago

    Their should be a braided strap along the top back box that has a hole for the truss head screw.
    The braid is stapled to the bottom surface of the top backbox.
    If the braid is not present, it could have been removed by someone.

Did anyone ever have this issue? thanks

    No G.I. lighting? Check the rectifier board fuses.

    #9 1 year ago

    this may be a dumb question. I'm green when it comes to fixing these things but where would that be located?

    #10 1 year ago

    Turn the power off to the game. They are in the lower body of the game. You can pull each one and check if they are good.

    I was hoping it was something on the easy side. Haha. Do a little reading and if you can’t get it, one of the big guys can walk you through it. Good luck.

    GI lights come right off the power supply and (typically) have no connection to the computer of the game. If all the playfield GI is out but you are positive the fuse is good you have a loose connector or broken wire. Start with the playfield power connector plugged into the power supply. There is a triac in all of this so see my further notes....

    It's been pointed out there is a lamp flasher and triac to power the GI. That's probably where the fault is. See my post below...

    #19 1 year ago

    This is incorrect, there's a Traic that turns the GI light on and off, during different game modes.
    Its mounted next to the power supply.
    I had same problem with mine, I just bypassed it.

    #20 1 year ago

    Hey guys thanks for the reply. I do have some lights lit on Playfield. Only ones not lit are all under Playfield plastics and pumpers. Also wdenni do you have a pic of triac that you bypassed. Meanwhile I will check wires thanks again.

    #21 1 year ago

    Thanks Wdennie, I completely forgot about the triac. That is most likely the problem. There is a lamp flasher board on the playfield that needs a load lamp to activate. Sometimes this lamp is bad or missing or replaced with an LED. If any of this is true the triac will not activate and there will be no playfield GI.

    #22 1 year ago

    Q19 is the coin lockout coil, nothing to do with your issue.

    #23 1 year ago

    Where is this triac board? On the Playfield?

    Reread post #19

    #25 1 year ago

    Should be mounted in the metal plate next to the power (fuse) board near the transformer

    #26 1 year ago

    thanks, guys
    had the time to mess with it today. after hrs of going nuts, I figured out. Aux driver board under the playfield. I resolder the pins. now lamps work but I must have messed something up with soundboard. green lite flash 5 times at boot up all good. but no sound. when I press on sound rom U4 I got sound pulled it out to reseat it and now nothing. could it be the rom. and where can I get new ROMs already set up for the game? thanks

    #27 1 year ago

    I also have another soundboard but the green light stays on after boot up.

    #28 1 year ago

    Ahhh, you have the domino effect.
    You know, you try and fix one thing, then another shows up and then another and so on.

    #29 1 year ago

    lol, this machine was working fine. this all happened last Saturday. do you know of anyone that repairs bally soundboards?

    #30 1 year ago

    Also, a Harlem Globetrotter SND board.
    But I am on the west coast.

    Yes, I have repaired different pinball boards...
