Hi focusmediagroup, AlexF +
I studied the schema "Soccer" and I found a little fault in the schema (see at the bottom of this post).
In later games ( ONLY ONE BALL, but a Ball-Count-Up-Unit) there is a relay named "Ball-Index-Relay" - to tell the machine "the player REALLY is playing a given ball". The Ball-Index-Relay starts pulling with the first Point the player makes. The Ball-Index-Relay is pulling (keeps on pulling) until the player looses the ball. The machine changes to the next Ball and cuts the "Self-Hold-Circuitry of the Ball-Index-Relay -> The player launches the new ball -> make a point -> Ball-Index-Relay starts pulling and so on.
In the early days - with REAL 5 BALLS the manufacturer made an relay with the same functionality and named this Relay: "GAME-RELAY". Please do not mix "Game-Relay" and "Game-Over-Relay" - the "Game-Over-Relay" is to tell the machine "The game has ended".
In words: You start a game. The Game-Relay is not pulling. A "Make and Break Switch" on the Game-Relay is in the state "Make connection for / to let current flow to the "Ball-Release-Coil"". Therefore (at start of the game) the Ball-Release-Coil starts pulling and keeps on pulling and by this the 5 Balls can roll down into the tray. The player launches his first ball -> the Ball makes a point (on the counter-Unit) -> The Game-Relay starts pulling (and keeps on pulling until the end of the game). When the Game-Relay is pulling the "Make and Break Switch on the Game-Relay" opens the Holding-Part (of this switch) -> the Ball-Release-Coil looses its current and gets inactive (no more pulling) -> played balls will be stopped. As the Game-Relay is pulling it closes the other part of the switch -> when the player has lost ALL his 5 balls -> through some switches: Current can flow to get the "Game-OVER-Relay" active.
In short: Line cord is pulled, so all the relays are inactive -> line cord pushed in and Left-Flipper-Button is pushed -> the Hold-Relay starts pulling. You start a game -> The Ball-Release-Coil starts pulling and stays pulling until the player makes his first point -> the Game-Relay starts pulling (and stays pulling until the game ends) and the "Game-Relay-pulling" cuts the current for the Ball-Release-Coil, this coil stops pulling -> played balls will be stopped.
focusmediagroup: Do the relays in your pin have tags with text-written-on ? Find the "Game-Relay" -> does it pull (AND STAY PULLED) when You make the first point ? Can you find a M&B-Switch on the "Game-Relay" (3 blades, the middle blade either has contact with the upper blade - OR: has contact with the lower blade). Check this M&B-Switch (clean, working, wires solderd on ?) and look if the Game-Relay STAYS PULLING after You have made the first point (on the counter).
The "Little fault" in the schema ? -> The text "Game Re." on F-9 is wrong to me. I believe there should be written: "Game OVER Re.". With "Game-Over-Relay" I understand the schema. Greetings Rolf
