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.

  1. This is a hyper extended end of a magsafe.  It is no longer working due to the wire having pulled apart.

  2. 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.

  4. 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.

  5. 1.) Take the good end of the existing wire and strip it.
    • 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.

    • Plug in wall outlet and install on computer to test.

    • At this point there are still exposed live wires carrying DC voltage. To eliminate risk of shock or shorting, cover the bare wires in electrical tape, heat shrink tubing, or Sugru.

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. :)

Could you please make the same guide for a L connector?
