OK I am a first time poster and I just got my first pinball machine, which is a Bally EM Bon Voyage. I bought this machine to 1) have fun playing and 2) go through it and learn how one of these works and hopefully how to fix it.
I got to #2 pretty quickly.
When I took delivery, it looked like everything was working as normal. I started messing with it, and messed it up!
What was I doing when it stopped? Something fairly innocent, or so I thought. I was just changing around some of the settings plugs, to see how they worked so I could figure out exactly where I wanted everything. (I thought the machine was too easy the way it came set up). The last thing I did was to change it from a 5 ball setting to a 3 ball setting. After I did this, I found myself in my current condition.
The current state: 1) Turn on the power switch. Nothing at all appears to happen. I believe this is normal. 2) Hit the left flipper. The lights all come on, and the Lock relay activates. Nothing else at all happens. Putting in a coin or pressing the start button (with credits shown) does nothing. Game Over light is lit. I can make some things happen by manually activating some relays, but I would rather be methodical about it, hopefully with some help here. I also just got a schematic in my hands and I have been studying that, and I have read quite a few of the usual articles and also the postings here.
What have I done so far: 1) I replaced the power cord. The one that was on it was a horrorshow, with at least 3 electrical tape splices. At one point I accidentally stepped on it and sparks flew. I put a nice new power cord on it. 1b) Checked the voltages at the transformer. It registers 6.3 VAC for the lamps and 58.3 VAC for the solenoids (it is on hi tap). These are normal according to the sticker in the machine. 2) Checked all the fuses using a DVM. I check the fuse and also checked it at the fuse holder and at the solder joints. All good. 3) There are 2 quarter coin machines. They were both working before. One of them had a solenoid on it which was pretty fried and the wires to it were really burnt. I am pretty sure this was a Coin Lockout Relay and it is OK to remove it. So I unsoldered it, taped up the wires, and removed the relay. 4) I checked all the tilts. The bob tilt and the ball tilt work as expected, when closed it causes a tilt via the tilt interlock relay. The tilt light comes on, and I can reset that tilt by manually pushing back the tilt interlock relay. There are 3 slam tilts, these all work as expected. When one is closed, it makes the the delay relay activate, that has a flasher lamp on it, and when the lamp cycles, the delay relay opens back up.
After reading as much as I can, I presume its all a matter of a startup problem. Based on the symptoms, it seems like a very likely culprit would the the Game Over relay. Here's where I am now. The schematic does show a Game Over Trip relay on the list and on the schematic. But, I can't find that relay anywhere! It's driving me crazy. All the relays are nicely labeled, and there is no relay labeled Game Over (that I have found yet). What I do see is a label Game Over at the last position of the Index Reset Motor Cam, which is a long cam with a stacked switch position for each of the letters in BON VOYAGE. I cleaned those switches but as of now I don't know how I would adjust those, or if they are connected to the Game Over relay, which as of now I can't find......
I'm willing to try any and all tips (that I can figure out), and put up pics. I'm not sure if this is something simple (because it was all working) of if I somehow botched the whole thing up.
