How to repair the Apple MagSafe2 Power Adapter with a Damaged Wire

Difficulty

Easy

Steps

Time Required

15 minutes

Introduction

How to disassemble the connector if the wire is damaged ?!

Tools

Step 1

To disassemble the T connector, you need to cut the wire 1 cm away from the connector.
Pull out the remnants of wire.
Take a metal rod 4-5 mm in diameter and push out the inside of the connector through the lumen (hole) of the wire.
It is easiest to do this in a small vise,

Step 2

Due to impact forces the inner part of the crimped metal will bend. It must be returned to its original shape.
This is easy to do with a regular screwdriver.
ATTENTION! Do not damage smd (surface mount device) light-emitting diodes and resistors.
After that, you need to solder the metal sheath back to the board.

It was very difficult to do.

once extracted the metal shield (i did it with a small torx (on the whole of the cut wire) and a hammer).

then you have to push out the wires left in the tube .where there is the red cross on the picture

after i left 1 mm on the inner wire and 5mm of the outer wires.

it was very hard to tin solder the inner wire to the little silver plate (which is on only one side / under the center of the red cross of the pic )

once by miracle the inner wire was soldered to that part. the 5 mm outer wires were already wrapped around the inner wire with 2 mm gap between them.

you push a many outer wires as you can inside de metal tube and solder them to it. not too much to be able to push the metal shield back. Test if it works. put the shield back. It will not enter back completely but it s ok. it works again . some glue gun, electrical tape and it does it s job.

Step 3

Cut off the damaged cable and tin (the end)
The Outer part = GND
The Inner part = +14.5

Step 4

Slip the heat shrink and the outer part (plastic housing) of the connector onto the wire.
Solder the wires,
From the factory, the GND is simply crimped with an metal part, but I also soldered it for greaterreliability
Assemble connector
It is very easy to press it back in with a small vise.

Oddly enough, I don't know how to fix that typo yet...

Thank you very much for this guide, also with the pictures. This was really helpful.

I would like to say, that the time required was a lot more for me, about 3 hours in total.

My cable fell apart and the cable coating came off, so I have applied a heat shrink sleeving first over the part of the cable without the cable coating, then another sleeving above the whole cable.

The connector was glued inside, so it was difficult to get off the cap and later to get rid of the old cable, which was still stuck inside. After drilling into the metal crimped part, I could remove the remainders of the old cable.

Now I'm really happy, that the cable is renewed and that it works well.

Is there a way to change the magsafe adapter into a type C? i have a spare type C connector with the pins so what im asking is if it's possible to solder the inner part of 14.5V and outer part GND into a type C connector

Type C chargers have different voltages for their specific units so probably not a great idea to try ;)

For me sadly this tutorial didn't work. My connector was also glue on the inside and circuit was covered with some sort of resin. I destroyed part of a circuit while removing remaining cable from the charging circuit. I later figured out that it would be better to salvage parts of charging cable that were still sticking out of magsafe 2 connector, connect them in wire and protect with heat-shrink tubbing. Maybe next time.

I still have to say thanks to the author of this tutorial, since I think repair is our hope out of grand consumerist culture.
I do hope my comment serves as a warning to fellow fixers when dealing with original apple chargers.

Step 4 greaterreliability > greater reliability ;)
