Ibanez Musician MC900 - wiring schematic help

Hi to all here!

i need some help, preferably from a MC900 model owner, i have the wiring schematic for the bass but following that doesn’t seem to help me much 🤷🏻‍♂️🤦🏻‍♂

Tried to replace the jack output but doesn’t work, tried to wire the old one the same way (i guess) and didn’t work as well!

Everything was working before 🤷🏻‍♂️🤦🏻‍♂️

So need someone that can help me with some pictures from the wiring and jack output!

Cheers and thank you! ☺️

Only 3 wires need to go to an active (TRS) jack:
- signal out (tip)
- ground (ring)
- battery negative (sleeve)

I can't really see from what the pics show, but in essence, if you can map out what is currently not connected to a jack, one thing should lead to ground stuff, one thing should lead to the battery negative, leaving the hot out remaining.

Figure out which solder points connect to the jack where, then connect accordingly.

And if you can take a pic of what is currently not connected, maybe we can see what needs to go where better.
