I have a 1975 williams Toledo 2 player pinball machine. When i push the replay button it goes into reset the machine starts resetting. The scores reset but the bonus unit does not reset and go down to 0. So in turn the ball does not kick out into shooter lane. I can push the ball out into the shooter lane manually and everything works perfect until the ball drains. It does not recognize the ball drained. I have a schematic for the machine but something was spilled on it at sometime and it can not be read. Any help would be great. Thanks

If i manually kick ball over to shooter lane the bonus unit increments up fine during game play. bonus unit works fine incrementing up and decrementing down manually. The lights switch like they should up and down as i manually operate the coils. When i manually take the bonus unit down to the zero position it will make the outhole kicker coil activate and go back up to 1000 like it is suppose to. If i set the bonus unit on 1000 which is as low as it will go and stay there. Then i trip the game over coil. When i hit the the replay button it does the same thing bonus unit will not reset or go down to 0 so that it can kick the ball over to the shooter lane. It does the exact same thing if bonus unit is on 1000 or say 9000.

It only steps down if i manually do it. If i set it on 8000 it will stay on 8000 if i make the game go in game over and restart it how ever many times. It never steps down on its own. It does not recognize if the ball drains. It is like the bonus unit is not being told to step down. I cant tell what switches are included in this circuit because my schematic is not readable.

Ok if i put the bonus unit on 8000 and i activate the outhole relay it kicks like it would to kick the ball out but it increases the bonus up. To 9000 then 10000 etc.

I guess what i need to know is what is suppose to make the bonus unit go down?

UPDATE: I got it figured out. The outhole switch was shorted to its self. The extra leaf was making it have connection all the time. I adjusted switch now it works good. Just incase someone else needs this info there is also a switch on the regular bonus relay that is inline with outhole switch. Thanks for the help.
