Hi my name is Jeff. I recently purchased a 1976 Segasa Sonic Faces Pinball machine made in Madrid, Spain. There were several problems with this machine when I bought it. After purchasing the wiring schematic / Diagram, I was able to troubleshoot most of the problems. First off, the Bridge Rectifier was blown. There was no power to anything on the machine. I replaced that, and the 1uF 200V Capacitor related to the Bridge Rectifier. There are only a few components on this EM machine. I was able to verify the other Cap, resistor, and diode are all good. Second, the wiring on the transformer was shotty, and looked like there could have been some wire shorting going on. I can't be certain though. I re-wired, soldered, and shrunk wrapped all of the wires coming from the Transformer, replaced some blown fuses, and turned the toggle (Power) switch on. The Pinball machine came alive!! It started to fire all of the coils, and solenoids, actuated bumpers, and lights, solenoids were making the chimes ding, in some kind of a loop. I found out about having to set up the machine. I set the Score motor wheels to match the schematic. turned the machine on, and now It's sitting idle. Great!!! However, as soon as i put in a credit ( add a quarter, or manually push the coin contact, It goes right back into the crazy Firing solenoids, chimes just like before. I am able to actuate flippers, but the machine is going crazy running through this loop, like before I set the score motor wheels up. Is there other things to be adjusted before this will stop? The scores on all 4 players read all zeros. I did try to ad credits to the machine, but when I press the play button, nothing happens. I have to press the add credit contact ( add a coin) to get it to do anything. Any help in this would be greatly appreciated. I have spent lots of time repairing this Pinball Machine. I would love to be able to now set it up, and play it.
