Hi,

Another problem I face is the following: when all the balls are in the through and the ball of through 1 is ejected to the shooting lane, a second ball is ejected as well, so 2 balls will be launched. If the ball of the last through is removed, the problem no longer come up.

I replaced the eject opto boards.

Strange, if anyone could help, it would be great. Thanks

Bedankt pinballrockstar. It is for a pin that I sold a few months ago. The problem came up before, I replaced the boards. it was working then. Where would you see a problem in the wiring ?

Yes,the second part of your post is normal, when the game does not detect the ball via whatever switch, it considers that the ball might be stuck somewhere and it activates all coils in order to unlock the ball, hence the game.

When you say the game stops and starts clearing, is the ball stuck somewhere ? Does the game behave as if the ball had gone out and the pin is trying to locate a missing ball ? is it random or in a specific situation ? In that case a sequence from the ball(s) launch will help to better understand.

Sorry, I am not an english or US native. by drain, you mean let the ball go down and leave the game ?

In that case, it means that the game does not record the ball exit and thinks the ball is still in play. As nothing moves anymore, it starts activating coils. the problem is linked to the microswitches in the through (I think there is no longer a outhole switch on these games, to be checked) which do not detect the ball that went out of the game.
