My first post, though I have read lots of interesting and helpful posts by others. I'm trying to fix a pinball for a friend, have a schematic, but I think some things are either mislabeled or not labeled. The issue is , it's a four player game, but when I try to set up the second player, the coin unit resets and goes back to single player. I can manually set up multi players, but when the score motor runs (which it does when I push the credit button on the door), #2start relay resets it! Got any insight for me?
Thanks in advance.

Thanks for the quick response! I'll see what I can get soon.

Howardr,
No Kinkos or Staples locally. I scanned and stitched with ICE, turned out clear,but it's in three columns. Was going to post to IPDB, but I'm not the original author, and don't know the copyright status..... I'll send the files to you if you give me your address!

o.k., but it looks like they have to be posted separately, because the files are too large. Here's the first column.

And the second....

Thanks, HowardR. I'll look at that tomorrow. Played it a bit tonight as is, and noticed that as soon as the fifth ball was done playing, the score tallied up, then reset to "0" and first ball.......

Thanks for the help. The contact on the first ball relay was out of adjustment,causing a coin unit reset with each credit button push. But I still have a question a out that relay. It's labeled #1 start relay, but is that the contact or the coil? Would it not chatter if that contact was on the start relay? The same with #2 start relay. Also the 1st ball relay. How does that work?

And the game wants to reset itself. Play any number of players, and after the last ball, it resets and zeros all the scores,

I did set it up for free play by closing the contacts on the reel. I'll try resetting those contacts, because it worked properly before.

Even with a piece of paper in the end of spool switch, it still resets the game.....

It appears there was a spec of metal in the contacts for the credit reset relay, closing the game reset relay. Played it quite a bit and worked fine. New rubbers and two score reel solenoids on the way for player four, and it can go home! Thanks!
