Alright, so today on Repairs101 I thought Id take you through the process of making reliable and weatherproof crimp connections for six, twelve, twentyfour and thirtytwo volt electrical systems. OK well I think pretty much everyones had a kit like this one where you get a multipack full of all kinds of different terminal connections and butt connectors and bullet connectors and even some fuses thrown in for good measure. And, you know, it will come with a crimping tool wire stripper that looks like this one here and its going to be a reasonably good connection and serve you fairly well.
But I dont use these anymore and I dont use this crimp tool anymore. I find the style of insulated terminals to be inferior to uninsulated. So I much prefer to use uninsulated terminals like these ones here and a pair of terminal pliers like this one and a piece of shrinktubing over the end. If I cant find uninsulated terminals Ill take the insulated type, just grab the end of it with my terminal pliers and just pull it off like that and then its uninsulated. OK so Im going to take a piece of ten gauge.
Wire you can see its marked there. OK so Im just going to take a piece of shrink tubing and cut it down to size and before we do anything were going to shrink a little piece of shrinktubing over the end. Remember to do it first because youll find you cant do it last. Ill grab these wirestrippers and take the end off real quick. There we go. I strongly recommend a pair of strippers like these to anybody who intends to do a lot of wiring theyll save you an awful lot of time. You squeeze the handle and the.
Reliable Crimp Connections
Jaw closes to hold the insulated part of the wire. Then you squeeze some more and the cutter comes up and grabs the wire and then you pull it apart with leverage. Put it in the slot marked for ten gauge wire and its stripped. Just like that. So at this point to dip it in some dielectric grease is always a good idea so you just want to take the end of that and there you go. OK now thats been dipped. So there we have it marked twelve and ten gauge and we know were using a ten gauge wire because.
It says right there. Now Ive dipped this end and it wouldnt hurt to dip this end. Just put a little shot of grease up in the middle of that. There it is. As you can see theres a seam in the construction of the terminal, where the saddle sits for the wire you can see theres a seam. So its very important to put the seam in the semicircle part so that youre pushing the male aspect of the pliers into the back of it. So you want to load your terminals so that the seam that seam right there.
Loads into the semicircle side of the terminal crimp pliers. OK so you just load that in there like that and you can see the male aspect is going to push up through the back side and do the crimping from the back side. So were going to load the wire then which weve already dipped. Im going to give a little squeeze and basically its done. And this is a very reliable crimp connection and thats what it should look like when youre finished. The impression from the male aspect of the crimp tool will be in the.
Back like that, nice and neat. So all thats left to do is shrink on the tube. Im just going to slip this shrinktubing up over the connection. Now you can use a butane torch like this one, or you could use a heatgun and you can use a propane torch as well but the propane torch youre going to find is throwing too much heat. You want to start at one end and then work your way to the other. It doesnt really matter which end you start at and work towards but you dont want to start in the middle and you.
Dont want to trap any air inside of it at all. You just slide on your piece of shrink tubing, and then just go around real light and easy. You want to start at one end and work your way down to the other and it will melt right on there sweet as you please. And there you have it I may have even overdone it a little bit. Whoops. You can see Ive overdone it a little bit. A little bit of charring but Ill just wipe that off. Its.
