I decided to walk through the operating instructions in hopes of find where the system fails.
1. Inserting a coin or pushing the replay button actuates “S” relay (start relay).
2. This relay will lock in through its own switch and a motor 2B switch.
3. “S" relay starts the motor running.
4. 11SB1 11 relay and the total play meter are actuated by a switch on motor 2C through a switch that has been closed on “S” relay.
5. When “SB1” relay is tripped the score units and player unit reset sequence starts. The 1st player score units reset to zero through the P3 switch stack on the player unit by motor switches 1A & 4A. When these units reach zero the player unit steps once, the 2nd player score units reset to zero through the P4 switch stack on the player unit by motor switches 1A & 4A. When these units reach zero the player unit steps until P5B opens. The score units and player unit are now reset.
6. The control bank is reset by a switch on motor 3C through a switch on "U" relay.
7. Inserting additional coins or pushing the replay button will actuate the 2nd player relay (PB) through motor 2C switch.
8. Place the ball in the outhole. The ball return switch closes and completes the circuit to "Q" relay. A switch on "Q" closes and through switches on Motor 1D, "J" and "I" completes the circuit to "0" relay.
I get this far and though it says "O" locks in the next step the act of locking might be for one second so I can’t say for sure if it locks or not but it does energize and the score motor comes on for 1/3 of a rotation. At this point the game goes to game over. The ball return coil does not energize and receives no power to do so.
My questions are:
Is 1/3 of a rotation enough to actuate motor 4C to allow the ball return coil to energize?
If not, why is it being cut off early?
If it is then where the power for 4C?
If I do get the power to the "ball return coil" to shoot the ball onto the runway, will it just go to Game Over because of another problem remaining?
Please offer suggestions or let me know if I should go in another direction. - Tom
The following paragraph is how it should finish.
"0" relay locks in through its own switch and a switch on motor 2B. When "0" relay is energized, motor 4C actuates the ball return coil (which kicks the ball onto the runway) through a switch on "0". The ball is now in the runway and is ready to be put into play.
9. The remaining balls that enter the outhole are kicked across the trough switch which pulls in "P" relay. "P" relay pulls in "0" relay which runs the motor. Switches on 'XB", 'ZB', motor 2C, "P", and motor 1A advances the player unit the required number of steps determined by the player unit switches and the player relay. (PB)
WHEN A TILT SWITCH IS MADE THE PLAYER LOSES THE BALL IN PLAY. IF THE PLAYER CAUSES ONE OF THE BOUNCE SWITCHES TO OPEN (IN THE LIGHTBOX, BOTTOM PANEL, OR FRONT DOOR) THE GAME WILL BE OVER. ADJUST THESE SWITCHES TO YOUR NEEDS.
