How to repair a power cord that has been dog chewed.

Anyone who owns a dog, cat, or rabbit probably has had this happen at one time or another. And this is what the result usually looks like.
So I’m going to explain you how to fix this.

The first thing you’ll want to do is take some cutters and just amputate the bad part of the cable. Now the goal is to splice the two remaining pieces back together. Start by using a knife or razor and careful cutting away about an inch of the rubber insulation, but be careful not to cut too deep or you’ll damage the wires inside.

Eventually you should be able to pull the insulation off, revealing the wires inside. Be sure to do the other side and both sections should look like this. next thing you’ll need to do is strip back the insulation on the smaller interior wires. Again, being very careful not to damage the wire inside.

Once you get them stripped, twist the strands to make a more uniform piece of wire. They should look like this when finished. Then do the other side, eventually all 4 should look like this. Ok, now it is time to get the soldering iron out.

The goal here is that you want to tin the leads with solder. But don’t heat them up too much or you’ll melt the insulation. Now we need to measure off the heat shrink.

So put the wires about like this, overlaping slighty. Now you can figure out how much heat shrink you will need. OK, next go ahead and slide the heat shrink over the wire and pull it back to a safe distance where it is away from the heat. if you want, you can try using smaller heat shrink for these wires, but this is really hard to do because they tend to shrink before you are ready for them. So I won’t be using these.

So, now it is time to line these wires up and melt them together. I know I look really shaky with the soldering iron, but I’m at a really hard angle here with the camera in my way. OK, the next step is to use pliers and work out any sharp edges or hard angles that might eventually tear through the insulating tape.

OK, since I’m not using heat shrink on the smaller wires, I’ll be using plain electrical tape. Ok, now it is time to pull the heat shrink over the new area, and use a cigarette lighter or a heat gun to shrink the stuff into place. The final product will look like this. Alright, just a few final notes on this. For anyone who thinks this splice looks ugly I would just like to mention it usually looks better if you have black heat shrink on a black cable.

Or in this case with a white cable, I should have white heat shrink. amputate the bad part of
And, uh, this is just what I happened to have on hand and so thats what I used. Also it looks kind of lumpy and it would actually be possible if you wanted to take the time, you know I just put the one strip of tape around. but if I wanted to take the time to pad the tape where it was even all the way across, um, this would look less lumpy. I’d also like to mention some cables, um, instead of having two wires in them, are more like a coaxial cable where you have a shield of wire around with a center wire in the middle.

And you can still splice those too.
Typically all you have to do is take the shield and pull it out and twist it around and make it like a single wire. So you can do either kind.

Anyway, I hope this was helpful to somebody and I’ll see you next time!
