Re: Tech: Pat Hand starts on ball 2

ok this can be frustrating. my question is any idea on what might cause
the step-up coil on the ball count unit to energize during startup?

here is the start-up sequence from Marvin's website for a williams
game. (with my problem below the steps)

1) When the start button is pressed, the credit unit is decremented.
This is done through the credit unit zero position switch and the 2nd
coin relay (and the ball count zero position switch).
2) The end of stroke (EOS) switch on the credit unit decrement coil
will energized the coin relay.
3) The coin relay will trip the game over relay.
4) The coin relay will energized the reset relay. The score motor will
run.
5) The reset relay will energized the ball count unit reset, through
the score motor.
6) The reset relay energizes the 2nd coin relay latch and game over
relay latch coils.
7) The reset relay will energize the score reset relays, through the
score motor.
8) The score reel reset relays will zero the score reels, through the
score motor. The score motor will continue to active the score reset
relays until all the score reels reach the zero position.
9) The reset relay activates the bonus unit coil until the bonus unit
zero position switch is activated.
10) When the bonus relay drops out, the outhole relay is energized
through a different bonus unit zero switch and score motor switch.
11) The outhole relay will run the score motor. The bonus unit will
step up once. The ball will be kicked to the shooter lane.

Most of the time it appears the machine does this, however, the step-up
coil on the ball count unit is energized during step 10 right after the
outhole relay is energized (causing the game to start on ball 2). A
few times the outhole relay did not energize and when that happened a
few times the step-up coil on the ball count unit did not energize and
a few times it did energize. We just kept restarting games over and
over again watching everything and got frustrated because without doing
anything, it wasn't consistent from time to time.

in all cases whenever we did get the startup sequence to go correctly,
the credit unit would never step-up to add additional players to the
game. we were able to manually step up the unit and add all 4 players,
play games and everything else seems to work fine. all score reels,
all swithes bumpers and flippers.

thanks again for your assistance.
