Wiring in guitar repair?

I bought a white ibanez flying v at a guitar center for brand new that was on sale for 250, after a couple days of playing it, the sound went out. i opened the back plate and noticed ther was three wires that came off the the toggle switch that selects the pickups. one white wire and two red wires. i tried taping the white wire and one red wire and i got it to work for a awhile then the tape came off. is there anyway to fuse these wires back on properly?
