On reset for a new game the 1,000 point score reels do not reset to zero for players 2 and 4. The game knows the reels are not at zero, the score motor repeatedly cycles and the 1,000 point relay is repeatedly actuated but the reels themselves do not move. When I manually reset the reels to zero the score motor stops and the game is ready to play. During game play the player 2 and 4 1,000 point score reels operate correctly. I don't have a schematic, any suggestions of where to look to resolve this problem? Thanks.

I finally was able to attack the problem with your suggestions and the score reels reset as they should. Thank you!
Next question - The game always resets to a four player game even though I only hit the start switch once. The coin S.U. unit does not appear to have any effect on the game status. I'll manually adjust the S.U. unit but no matter what I set the game is always four player.

The display accurately reflects the position of the S.U. unit but it has no effect on the actual gameplay, no matter the setting, no matter how many times you hit the credit button, you always get four players. The lights indicate one player, or two player or three player but you always get four player.

Another spot on suggestion! Thanks, now I'm down to one problem. The match step unit is not being energized,
what energizes that step coil for the match unit?

Thanks again, the relay was working fine but I needed to clean out the coil sleeve. Now it's time to see if I can get past 99,999!

OK, I should know better...I jinxed myself. The bonus unit steps up as it should and steps down as it should but it is not sending a pulse to the 1,000 point relay. Any suggestions?

After I examined the schematic I went back and experimented. I get the appropriate bonus points if either the double or triple bonus relays are activated. If neither the double or triple relay is activated I do not get any bonus points. As I look at the schematic, I can't determine what path the circuit takes if neither the double or triple bonus relay is activated.

Thanks, it was the impulse score motor switch C

None of the 10 point score reels are advancing the 100 point score reels when they pass the 90 point position. This is for all four players. I checked the 10 point score reels for all four players and the 9 point positions are all properly adjusted. I checked to 10 point score relay and the relay position that activates the 100 point score relay (1A) as it passes the 90 position is properly cleaned and adjusted. I put alligator clips on the relay just to make sure closure wasn't a problem. This seems to indicate that the problem is somewhere in the Player Unit Disc. The schematic indicates that positions 1 thru 4 are in circuit to to 100 point relay thru the 10 point drum unit through 9 position. Where would I look to find the break in continuity?

Jumping 4 and 5 results in player 1's 100 point relay advancing properly. What's the fix for getting all the player's scoring to advance properly?
