Good Evening Experts. I’m an old guy knowledgeable of restoring vintage cars but new to pinball. Having fun, learning and remain in awe of the expertise on these forums.
Have an original 1966 Gottlieb Mayfair purchased in 1990 by me, kids used it extensively through 2005 and college, then sat unused for the last 17 years. Worked when last used. Bringing it back to life now for the grandkids. Systematically cleaned and renewed and now have most everything working with one issue. Unable to have two players. When I power up and press a game, it resets fine. When I select a second player, it registers the second player, then immediately resets. It will play a 1 player game, count the balls correctly, then goes to Player two after Player 1 completes ball 5. It then sticks on Player 2, ball 5. If you reset, same.
I can manually step the Balls Played Unit through all positions and it will register correctly, switching between each player with the correct response. I rebuilt that step Unit and it is not binding. It advances and resets smoothly. I can manually trip the PB relay (second player relay) and it will work fine. I can manually trip the QB relay and game over and Match will display correctly. Following the schematics....still learning here...it appeared the issue would be in the ZB, PB or H Hold Relay. H looked burned so I replayed it...still same issue. I’ve checked the SB (start relay) and it appears correct but that could be the issue and will revisit.
So, very much stumped on why it immediately resets to 1 player after pressing the game button and why the XB and QB relays will not function after ball five. I feel I’m missing a single contact that inhibits the sequence. Any advice appreciated and thanks in advance for any given.
