Introduction
As you can see by the photos, I took a broken and otherwise useless magsafe end and made a splice. After a resolder, the LED shows the computer charging.

This is a hyper extended end of a magsafe. It is no longer working due to the wire having pulled apart.
-
-
-
Use wire cutters to cut the wire of the magsafe some distance back from the magnetic end. I cut about 4 inches back. You can get much closer like maybe an inch, as you will see in the next step.

I used a utility knife to cut the nice white cover off the tiny printed circuit board. There is a molded plastic cover similar to hot glue which had to be stripped off the PCB.

-
1.) Take the good end of the existing wire and strip it.
-
2.) The interior wire, which is coated in white should be soldered on a square metal plate about one eighth inch square. This plate is opposite a small chip for reference.
-
3.) The braided wire coats the white interior wire, and is wrapped around it in two different directions. This wire should be peeled off and then twisted together.
-
4.) Then solder it in place opposite the chip and the other wire.

To reassemble your device, follow these instructions in reverse order.

Thanks a lot for the tutorial, worked like a charm and the result is quite clean too. You made me save 80€!
Works but looks like !@#$.
If it looks stupid, but it works, then it's not stupid. I'm certain someone has the skill to make that end look good.

Awesome! I had not used my macbook for almost a month, since my magsafe quit working. I was afraid to cut into the plug, fearing I might damage the circuitry inside. Once I saw the pictures of the inside of the adapter, I knew the correct way to do it. Thank you for the tutorial. :)
