When 'P5A' on the player unit closes, 'AX' and 'BX' relays reset through motor '1D' and switches on 'U', and “S” relays.
The reset cycle is now complete.
Inserting additional coins or pushing the replay button will actuate 'CX' relay through switches on 'U' and 'S' relays and a switch on motor '2C'
The replay button circuit opens when 'CX' relay actuates.
Place the ball in the out hole. The ball return switch closes and completes the circuit to 'O' relay through the zero position switch on the bonus unit, 'AX' and 'Q' relays. 'O' relay locks-in through its own switch and a switch on motor '2B'. When 'O' relay is energized, motor '4C' actuates the ball return coil (which kicks the ball onto the runway) through a switch on 'O' and normally closed switch on 'BX' relay. The ball is now on the runway and is ready to be put in play.
The remaining balls that enter the outhole are kicked across the trough switch which pulls in 'P' relay. 'P' relay runs the motor.
Switches on 'U', motor 2C, 'P', 'BX', and motor 1A advances the 'Player' unit the required number of steps determined by the 'Player' unit switches and 'CX' relay.
