Ibanez ATK400 - Wiring Diagram

[elephantstone]

Hey all,

I have searched the net for a wiring diagram for my Ibanez ATK400 but i can't seem to find one anywhere. On the off chance does anyone on here have one?

The bass is buzzing badly now and when I opened up the back there was a black wire that was unattached - which I'm presuming is the earth wire.

I've attached a photograph of the back of the wire incase anyone with a much better knowledge than me could point me in the right direction.

Many Thanks,

It's off of the jack socket - diagram below.
