After finishing the Fan Tas Tic and Cabaret project and both running smoothly and without errors, the next project is the Student Prince with some major failures.

The machine is buzzing and living his own live , eating fuses and a coil for dinner a few days ago.

I started to have a good look at the back of the playfield and found some soldering errors on the target switch close to playfield reel and on the top rollover switch were the wire was disconnected.
In the back box at least one soldering from a score reel was disconnected and maybe more. I think it could be 1 of the issues the machine all these bad solderings.
I also found a switch without a wire connected to one of the lugs of the switch and now i did not see and loose wire and i am wondering if this would be correct.

The main problem is the schematics who i cannot find in IPDB. Does somebody has a schematic of the student prince, i need to find out.

Thanks, Hans

Thank you for the answers. The photo attached is at the zipper flippers but were can i find this in the cabaret scheme. I did search for other schemes from other machines but did not find it. Maybe à suggestion from à game what can be used.
Thanks, Hans
