I told you ya had to be careful not to scorch it!
I don't know what height you had the flame on the lighter set too, but it should be set very low. It'll still get the job done. Start with the flame a good distance away from the shrink, and slowly move it closer until you see some shrinkage taking place. You want the HEAT from the flame, not the flame itself, to cause the shrinkage. When you see that shrinkage begin, slowly (or rapidly, depending on how fast the shrink is shrinking) rotate the wire between your thumb and finger so you apply the heat evenly to the shrink wrap. If you don't, you end up with an uneven shrink (which, of course, can be very damaging to the psyche {double entendre intended}). Learning can be such a painful process.
Good on ya for doing it yourself, Ken.
