Hey Guys - I just picked up a 1964 Bally Bongo EM. It is in pretty good shape. I have read through the pinrepair guide, but I have some questions. Right now it plays ok. The two major issues are no GI lights at all, and the number matrix (like tic-tac-toe) does not function (no lights on play field or on backglass).
I have read that Bally machines startup with no GI lights until either the start button is pressed, or the left flipper is pressed. The left flipper thing seems to be for latter Bally machines though. While doing a visual inspection, I found this cut and taped wire near the left flipper button. It is wired into the original unmolested harness and goes to a plug connector that connects from the coin door. For the life of me, I do not see where this would have originally gone. The solder contacts on the left flipper look factory original. Any ideas?
I did find a blown 5amp 6V fuse. I replaced it with a correct one, but have noticed no changes after that.
I would appreciate any insight you guys can provide. If you can point me in the right direction, I would appreciate it. I have attached a photo of the cut wire in case that helps.
I would like to modify it so that the GI lights come on when I plug in the machine - if anyone knows how to do this on an older Bally, that would be great.
