I have a problem with my magsafe 2 adaptor, it has been stopping to work occasionally for a while now. Until now I always managed to get it to work by yanking the cable (in order to unstuck the pins), however now this method is not working anymore. After the usual yanking, I decided to clean both the connector and power plug on my macbook with a toothbrush and cotton. For some reason after that it stopped working completely. I am able to unstuck the pins by softly tapping on the connector with my fingernails but it still doesn't work.
I have another non working magsafe 2, which has perfect pins and after cutting the cord now looks like this:
How dangerous would it be, to cut off the non working connector, expose the cables and connect them together by intertwining the stings?
Obviously I would isolate the two wires (copper and the other one) with tape and try to make a decent connection. I have done similar shenanigans with audio cables and it has always worked for a while.
I will buy another one, but need an urgent solution right now. However, I don't want to break the computer or start a fire over it.
