Start sequence of 1972-78 Gottlieb single players without a reset bank

Steps

• Replay button: start relay pulls in (it can be pushed in by hand on the bottom board).
• Hold relay locks on: playfield lights and part of the solenoid power path.
• Score motor runs; ball count unit resets to zero; drop targets or relay bank reset.
• V reset relay pulls in and releases the start relay.
• V relay plus motor zero the score reels; once all reel zero switches close, Vr pulls in and releases V.
• Ball in outhole: Ball Return relay pulses, outhole kicker fires; motor stops when Ball Return drops out.
• Ball rolls over the shooter lane switch: ball count unit steps to ball 1 and playfield solenoid power comes on.

Start relay pulls in, latches the hold relay (lights and part of the solenoid feed), runs the score motor, and with the motor resets the ball count unit, any drop targets or relay bank, and pulls in the V interlock relay. V releases the start relay and, with the motor, zeroes the score reels; when all reel zero switches close the Vr relay pulls in and releases V. A ball in the outhole then trips the Ball Return relay to fire the outhole kicker, and the ball crossing the shooter lane switch steps the ball count unit to ball 1, which switches on playfield solenoid power.
