is Electrical Tape Safe for repairs?

[Drunkenmaster]

I posted this in the Off-topic section but going to repost here to see if anybody else has anything words of advice.

I was wondering if anybody here has the knowledge of fixing a torn wire.
It's a Magsafe charger for the Apple Airbook. It has a tear on the secondary side. (The side that plugs into the airbook and not the side the plugs into the wall socket)
The plug that plugs into the laptop has 5 leads, the outter leads i believe is GROUND, and the inner leads are 14.5V 3.1A. and the middle pin is some Charge control Pin.
Inside the wire is A mesh wire (which i think is the ground) which wraps around another wire. The inner wire I think is the hot wire.
I just Twisted the inner wire together and wrapped a lot of tape around it to prevent it shorting to the ground wire.
then i did the same to the ground wire. I wrapped it around many times just to make sure it doesn't short.
and then i wrapped more electrical tape around the repair so it doesnt split again too easily.

My questions are..
Is it Safe to use electrical tape to make the repair. the wires are conducting 15V 3amps. Im afraid it may cause a fire but the tape does say Fire Retardant.


I do feel that it is safe, but i'm giving this charger away to a friend so I dont give it away if it's a fire hazard.

I did do a real good and clean job of the repair but am right now afraid to let my friend have it to use.

by the way, the tape is green electrical tape. I know i should of used the black. but I thought all electrical tape are the same cept it's used for colour coding.

if anyone has electrical knowledge please give me your input. I know i should of soldered the wires together but i still a lot on my mind about the electrical wire.


Also sorry if i posted this in the wrong place.. I know of no other forums..

Thanks. =)

It should be safe, I would get a piece of heatshrink tubing and use it over the tape just to make sure nothing comes apart.

Yes, if done right.

I second the heat shrink tube. Wy better than tape. Solder first if u can. Then should be good to go.

You can probably get an aftermarket charger too. I did for my old iBook.

I swapped parts from two of those old halogen Torchiere lamps. My black lamp fried, and they sold out of black, so I bought a white one to replace it. Snipped the wires, connected working part to the old lamp, twisted wires together, then covered it with electrical tape. It's been over fifteen years, and no fire or burning smells yet ... except for the odd insect that gets too close :).
