Have just done up a Judge Dredd, and everything is sweet except for a bizzare problem.
When the ball is directed into the left shooter lane from the Air Raid ramp, and it goes into missile launch mode, you are meant to hit the left fire button to launch the ball. Doesn't work.... BUT
The left fire button is fine in switch edges test AND during gameplay in that you can change the chain feature.
The left lane rollover switch is fine in test mode and gameplay when the ball rolls into the lane (except from the air raid), and the diode on the switch tests fine (disconnected one leg).
The solenoid that fires tests and works fine.
The clue i think is something to do with the rollover switch in the left lane, as in the switch edges test, when you press this switch, the deadworld motor and the crane motor both move for a half second (the left shooter lane solenoid also pulses ever so slightly (maybe 4-7mm of movement).
The other thing i noticed is during the solenoid test, if the coin door lockout switches aren't pressed in, every solenoid that should be firing (but doesn't due to door open) the motors turn a bit then as well as it cycles through the solenoids in the test, but when you hold the lockout switches in to fire the solenoids, the motors don't move (except during the appropriate tests)
I've seen some other suggestions that its something to do with the centre drop target, but the opto works fine, and they all reset fine as well.
Any help?
Thanks
Rob
