I have a LTD ESP Snakebyte and the bridge volume knob is overturning and I think it took one of the wires out when I turned it too much. I checked the wires that go to the input and both of them are in the right spot. However theres a red wire that splits off into three different sections and it's not connected to anything.
Some pickups have wires that aren't used, except for certain applications. If the guitar was working prior to the Pot being banjo'd then the problem lies with the pot. change it out. they are inexpensive and easy to swap out.
This is a common problem I see come through the repair shop. The nut holding the pot loosens, allowing the pot to rotate out of position from where it was mounted which can break off the wires at the solder joint.
As Todd answered in the comments, unless you know how to solder and follow a wiring diagram, the best thing to do is to take the guitar to a technician and have the pot reconnected and tightened.
