Working on restoring my first pin, a Gottlieb Cleopatra. I'm happy to say that I'm just about done with my restoration. Cpu, drive and power boards have all been replaced. All the molex connectors have been repinned. I replaced the drop targets, all the rubbers, and cleaned and buffed everything. So I thought I was pretty much done. I have a new Ni-Wumpf system 1 replacement board, so I did all the diagnostic checks. All the switches and light bulbs were fine. However, when it came to the coil test, all of them worked except one, the drop target reset coil. Once I fix that I think I can call this pin done! But the problem is I don't really know where to start. I did fully take apart this drop target assembly when I replaced the targets. Boy that was a pain in the butt with all those springs! But I'm almost 100% certain that I put it back together just fine. I took a lot of pictures before hand and studied it pretty well. The drop targets all seem to work if I manually drop them and reset them. The switches on them all seem to operate as they should and they are all normally open when the targets are up as you can see here:
When all five targets get triggered, the "Extra Ball When Lit" feature does light up. So even that appear like its working. It also does score points the initial time the targets are knocked down. But then at the start of a new ball, or when you switch players, it never resets the drop targets. Here are some pictures of my reset coil attached to the drop target assembly. Everything looks ok to me, but I don't necessarily know what to look for per se.
I can manually push in the reset bar attached to the coil with my finger and it does reset all the drop targets.
So, again, as far as I can tell everything is assembled correctly, everything is scoring correctly and lights up the appropriate special gameplay lights. The only thing not working is that the reset coil never fires and resets the drop targets. Can anyone give me any tips or tell me where to start looking to fix this? Any help would be appreicated! Let me know if you need any more info in order to help me! Thanks!
