My judge Dredd had been working fine however the last few times I played it started putting two balls in the shooter lane on start up. The first ball goes in like normal...then there is a 1-2 second pause and another ball is kicked into the Lane. It seems like it doesn't know the 1st ball is there. Any ideas on how to troubleshoot this would be appreciated. Thanks. After 2 balls are there it stops. It won't try to put in a 3rd. Even if I launch the 1st ball right away it will automatically load and fire a 2nd into play. If one ball drains the game is over.

I'd first check... correct number of balls installed in game? check shooter lane switch

edit: check trough opto board, dummy (me, not you )

Put new balls to guaranty consistent size. Trough opto board may be intermittent in spots but not sure. Is there a way to clean the Optos or adjust them? Or is the board shot altogether? Help verifying this would be appreciated.

You can try to clean them with some ethanol on a q-tip. Also check the trough for any divots. This can cause ball count problems.

Inspect the trough boards for dull or cracked solder.

Check if the transmitters actualy transmit, use a camera to see the infrared beams.

I had this problem. If you recently added the deadworld mod you need to put that trough plastic inside the trough. It de-magnetizes the balls or something.

Or count all the balls and make sure you have the correct amount. I found one inside the machine pinned against the ball corner and put it back on the playfield. Turns out I had seven in the machine and it did the same.

Or do the trough inspection like noted above.

Thanks everyone for the help! I swapped the transmitter board from my sttng into jd and it works. Now I need to figure out which component failed on my transmit board so I can replace it. I know they sell the board but it would be cheaper if it was a bad resistor or emitter. Any ideas how to narrow it down?

I am having the same issue. Originally the test report said I had a bad switch in the trough. Pulled that out and found a bad ir led that I fixed with solder. Now the test report is clear, but it's still kicking out 2 balls occasionally. Looks like I have a bad switch on the left ramp entrance.
Where is the transmitter board you replaced?

I'd try re-flowing the solder to the optos and board connector first. You likely just have a cracked solder joint from vibration.
