Hi people! I've been trying to iron out some minor faults from my JD running the deadworld mod with the L1 ROM. A couple of weeks ago the drop target reset solenoid started doing this:
I did manage to find a thread on (apparently) the same problem on another forum. As in that one, my target bank sometimes goes crazy right off the bat when a game is started, or like in the video I've added from mine, it might take dropping all of the targets once or few times. That particular thread seemed to focus on the opto board but frankly, I have real trouble seeing how it's connected to the problem at all. It might be, of course, but dropping $70 on a new opto board on a hunch seems a bit harsh. While in the test mode, the single solenoid fires perfectly and resets the whole bank, so I can't really blame the mechanics either. So I'd really, really appreciate any thoughts on the matter.
What I've done so far: 1) cleaned all the optos and the board connectors - there are scratches, but they seem to work perfectly. 2) Suspected that the solenoid isn't getting enough power and cleaned the solders from the reset solenoid to the best of my low abilities - note that I do not have flux or a solder vacuum so it's probably a little iffy 3) scratched my head for two weeks.
Can this be related to something else completely that screws up the logic that tells the solenoid to reset the drop targets?
