just if you don't know. You can splice the wire back again by pulling some crimptubing over the wire, then soldering it, pulling the tubing over the solder joint and then shrink the tubing with heat. It makes a great a durable spice.

you can buy the crimp or shrink tubing at radio shack. It comes in different diameters. It shrinks to about half diameter. Any heat will work - even a match held an inch away.
