Ok, so like it says in the title my CF won’t allow 2+ player games and I’m looking for advice on what to check as I’m a bit lost on EM repair. I also don’t have a schematic and honestly am not very familiar on reading them in the first place.

A few things I’ve checked and find odd that may help in pinpointing the issue. The Coin unit won’t advance to add 2,3 etc players. If I manually adjust the Coin Unit for a 2 player game, the game won’t advance the ball count unit, it will go through all 4 players on ball 1 (even though a 2 player game was started) and never advance to ball 2. If you play a single player game the ball count unit advances as it should. Thanks in advance for any help.

Bump for the night crowd.

MarkG you were right on with the reset relay, a clean and adjust and I’m now able to add players 2, 3 & 4. However what I had assumed was all 1 problem is apparently 2 issues. The game still will play through all 4 players even if only a 2 player game is started. It actually gives player 4, 2 balls before advancing to the next ball in play and starting back with player 1. 1 player games advance through balls correctly.

Ok so from what I can see the ball count unit is never energized until you’ve played thru 5 balls( 1 for each player and 2 for player 4). Coin unit then activates and the player reset relay gets powered and it moves to ball 2.

The player up unit activates after each ball, player 1-4 even if only a 2 player game is started. The exception of a single player game where all functions work correctly.

Coin Unit seems to check out good, doesn’t have rivets, it’s a circuit board style. No resistance on 2 & 3 player settings and jumping org-wht and wht-Brn still has same symptoms. What should I be looking at on Player up unit?

Ok MarkG we have success, I tested gray-red wire to white-brn set on 2 player and also to white-yellow for 3 player and had no connection so after looking around I found the wiper arm was a little loose and could get a beep if I pushed it with my finger a bit. So I removed the wiper arm assembly and adjusted that arm and now it correctly plays 2, 3 player games with correct amount of balls etc.

I really appreciate the help, I definitely couldn’t have done it without your help. I really need to learn how to read those old schematics some day. Thanks again!
