Judge Dredd
Bally, 1993Hello Pinsiders,
I have a JD and the crane won't unload the 3 balls in the planet with multiball. I checked the opto's of the through and at both opto's on the left ramp as well the one whioch the crane throughs the balls trough. THe crane seems to be in the right position, cause if I start up the machine and ther are balls in the planet it unloads them right away. Some times the crane does lift the balls with multiball, but then very late. What can this be? Any suggestions!?

I manually adjusted the arm till it looked right to me. With that test and the the T16 test. How do you know when it's ok? With the T15 it just says "please wait" and when you're finisched adjusting go to T16. With the T16 test the crane goed back and forth twice (without unloading) and then planet just keeps on turning. Switches 71 and 77 say Open and Switch 62 says Closed.
By the way: in testing mode it says check Switch 61 (Globe postisiong 1).
Switch 77 is Globe position 2, mine does flash closed in the T.16 test mode, good luck, hopefully someone with more experience can weigh in.
Hey Fulk, any headway on that? How's that switch looking? Im guessing you have the manual for it, its below the dead world rings, looks like directly under where the ball drops off the ramp onto the DWplastics
if the planet rotates constantly then you need to either clean or replace the optos that work with the interruptor ring on the base of the planet under the playfield.
These optos allow the planet to pause at the correct moment for the crane to lift the ball.
hope this helps
good luck
I think I have a breakthrought! Under the playfield I found a black circular piece
of plastic above the opto board. It has to slots. The plastic piece is loose (I believe I miss a tiny screw that locks it) ans it looks like the to slots in the circular piece should be fitted on top black pieces on the opto board.
Am I right?
If so, I can't rotate the platstic round piece to reach the black pieces on the opto board. Can I force this? Or is there another way? I don't want to cause more trouble!
I'm going to remove the planet rings. Perhaps, than I can rotate it.
I believe thats the opto interrupter and yes you need the screw to keep it secure, make sure there is no cracks in it as well. I got a aluminum interrupter replacement from pinball life or marco's, cant remember, for my ToM, not sure if they are the same part number
I don’t think we have enough info here. First off, you stated the machine unloads the balls just fine when there are balls in the ring, and that machine does a ball search when you first turn it on. That means the crane, works fine, as this is proper operation.
This sounds like an opto issue. First off, what roms are you running? If you have the DW ring with the holes for the balls to stay in, you should have got this from pinbits, and should be running their modded rom. If you are not, this can cause all kinds of opto issues, and the game will not play right.
If you have the proper roms, than anything is possible opto wise. If any opto is out, or flaky, this game loses track of the balls, and all kinds of crazy things happen, which is most evident in MB. If the rom is proper, I would go into the test mode and thoroughly test all opto switches to make sure they are functioning properly.
I tested the 2 opto's in the ramp and the opto which the crane throws the balls trough. Those all work properly. So do the ball trough opto's. Are there more I should check? How do I check or test Switch 72, 77 and 62?
PS: Doný know which MOd I have. I bought it with the Mod. See pic: $T2eC16N,!w0E9szN(mLvBQlrgjyS1Q~~60_84.jpg
I live in Holland and bought it from another home owner. I'm pretty sure it's the PC opto board. I have one more problem. Suddenly when the planet rotates it falters (or hesitaes) a little at a certain points. Any idea what might cause that?
I'm pretty sure now it is my Opto Board, but when I remove it the result of the T16 test remains the same (swith 71, 77 open en 62 closed). Switch 71 blinks closed for a split second. Just like before. Do you have any idea how that's possible? And like said before: Suddenly when the planet rotates it falters (or hesitates) a little at a certain points. Any idea what might cause that?
Slow down. Has it ever worked right in play?
As for the issues now, this could be related to the opto interrupter you move, or a ceasing gear box. JD is a complicated machine.
****Clarify the eprom concern though****, if you don't know, open the BB and report what the eprom is. IF this is not the pinbits one, of the closed holed ring, the only other one that would work is the L1 I believe, and that one is very unstable.
