I've made a huge mistake.

I wanted to be able to use the power plug instead of the battery, but the power jack wasn't working. These have a plug style that looks like a headphone plug. I opened it up, made some very minor changes to the power wiring and now that power jack works.

Fast forward a few months and one day my PDS 1700 makes no sound. I try battery power, and plug power, and I desperately try and remember exactly what I changed with the wiring. I don't remember what I did. I have searched the internet for a clear picture of the insides that shows the wiring from the battery and from each of the jacks up to the board. I'm not even sure if the molex-style plugs are oriented correctly at this point. I even desoldered the power plug jack in the hope that if I just try to get it wired back to battery power at least it might work.

I've been assuming this whole time that the wiring must be the issue since that's the only thing that I futzed with. If it is an issue with one of the ICs I barely even know where to start troubleshooting that. I'm attaching some pictures, suitable for framing, of my girl in her current state. If anyone has one of these they can post a clear shot of the wiring from that would be yeet deluxe. Obviously, any insight is very welcome here. This is a choice pedal and one of my favorites, the fact that it just stopped working one day has distressed me greatly.

I need to flange again.

Thank you, and you look nice today.

I'd like to add that I understand this is something I could likely figure out from reading the schematic. I don't know how to read schematics. That's why I'm asking if anybody can tell me which wire is supposed to go where like a goob. I haven't even been able to find a schematic, either.
