I done I think everything that a newbie should not do and made the pin worst than the way I got it. But after a few hard days of undoing what I done I am back to square one where I 1st started. Once the ball drains, the pin will not add the bonus points or advance the player, but will kick a ball out to play.
I thought that this might be a relay problem, and that is were I got into trouble filing the contacts. I since had to go back and adjust all the contacts to get everything working again.
I'm thinking now that I need to clean the player stepper unit, but thought that it would be best to get some advice first. I got a copy of the schematic and I'm trying to understand it.
