Ibanez SR1600 active function broken

Hey there,
So I have this Ibanez bass and for the last few years the active function has not worked. Passive is fine, but when I switch it over to active there is literally no sound (not even a hum). Naturally, I’ve tried several batteries, but the issue persists. I’ve started joking that’s it’s my bass’s kill switch; however as time has gone on I’ve wanted to get my active back. On the inside, no wires connections to the active switch seem to be amiss. There is one wire that runs from the pickups to the bass knob (see second photo) that is not insulated, but I’m not sure if that could affect the active system. I will attach photos to see if any of you can see something I’ve missed.
