I Am trying to fix a fault on my Zaccaria Supersonic. I hope there is someone that could give me some help.
There are ten lights on the playfield spelling SUPERSONIC, 9A on the Schematic. If any of these lights are on when the ball goes down the drain, when playing the last ball it does not end the game. The ball numbers go out and it shoots out another ball. When this ball goes down the drain it lights up GAME OVER and the game ends.
If there are no SUPERSONIC lights lit and the last ball goes down the drain TILT lights up for a second and goes out and then the GAME OVER lights up and the game ends.
The only other fault I can find is the anti slam switch on the coin door does not seem to activate the trip. It is normally closed. If I hold it open, any coins put in the slot do not give credit or start the game. If anti slam switch on the bottom of the cabinet is opened, the TILT lights up and the game ends.
I have attached the Schematic, it seems a little small. I can email you a better copy if necessary.
