This Williams Derby Day has been shopped and was working fine. I was not around the machine when it stopped working but this is what it does now.

You press the start button and the machine resets. It then counts all the balls 1-5 and goes to Game over without ever launching the ball. If you take the ball out of the outhole and start another game it resets and waits on ball one for the ball to be placed in the outhole, Then it counts all 5 balls and goes to game over.

This is a turret shooter game. Any ideas? Thanks in advance, Sean.

I don't see a Shooter solenoid coil on the schematic, do you?

I think its listed as a ball release relay. Located in G-21 on the schematic.

Quoted from seanduffy:

It then counts all the balls 1-5 and goes to Game over without ever launching the ball. If you take the ball out of the outhole and start another game it resets and waits on ball one for the ball to be placed in the outhole, Then it counts all 5 balls and goes to game over.

The Ball Count Step Up solenoid at 7-8 on the schematic will fire every time the motor turns and a Normally Open (NO) switch on the Outhole relay is closed so it sounds like the Outhole relay and score motor are staying active longer than they should.

The score motor (or control motor) at 6-7 on the schematic will turn when the Outhole relay fires.

The Outhole relay at 21 on the schematic is fired by a NO switch on the Ball Rest relay and the Ball Rest relay at 18-19 on the schematic fires when the ball is in the outhole. It sounds like all that is working as it should.

When the Outhole relay fires, it should in turn fire the Shooter relay at 8 on the schematic which should stay active until points are scored.

The Shooter relay should also toggle a Make/Break switch at 21 on the schematic that should allow the Outhole relay to relax, and enable the turret shooter button.

If the Shooter relay is not firing, check the two NO switches that should close to let it fire at 7-8 on the schematic: one on the control motor and one on the Outhole relay.

If the Shooter relay is firing, check that the Make/Break switch on the Shooter relay is working properly.

I got it figured out, the shooter relay was not staying energized through its own switch. It was pulsing with the score motor. I found three open switches (1 point 10 point and 100 point) that I believe someone with good intentions had made open when they should be NC in an attempt to fix a score unit reset problem.

thanks Sean.
