So I've got a BC. Rich Avenge Son Of Beast.

And here's my problem. No signal at all, can't get a sound through. The rheostat inside is wiggling and turning when i turn the volume knob, so i already know the solder holding that down is gone. once i reattach that to the body, it's still gonna give me problems, and this is why.

i know the image sucks but hey. you get the picture. see the grey wire at the bottom and how it's not attached to anything?

bit of a problem there. where am i supposed to attach it? any help would be greatly appreciated. i'm a f*cking noob with wiring.
