 Good news, today we're going to show you how to repair and fix your broken BT168 battery tester. Hey guys, njroute22.com here with another how to fix them up vlog. Now you have this, where is it? Where's my stupid battery tester? I left it, I'll put it up on the screen here. You have this BT168 battery tester, right? And it used to work, but now it no longer works. What do you do? Do you throw it out and buy another one or do you try to fix it yourself? In today's tutorial, we're going to show you how to do it. But just note, before we continue, this is for super duper mega advanced students only. And I would like you to repair this at your own risk. We don't hold you, don't hold us responsible for anything that goes on. This is some seriously advanced techniques. Let's get started. Hey there, njroute22.com here. We're going to fix, this is our how to series here, and we're going to fix or try to fix a BT168 battery tester. Now, these things are like five or 10 bucks online. If you don't want to be bothered, you can just buy another one. But we don't like doing that. We like trying to fix things first. So the first thing I want to say here is that I found that this is broken. Because if I test the battery, nothing happens. But if I test a nine volt battery, it works. That means there's something broken inside. That's when you can determine that one thing is broken and one thing works. Just to show you here is a digital one. And I will test it. It says 1.39 volts. And just to show you that the battery was good, this battery says 9.88 volts. So I know the batteries are good and the battery testers bad. So like we learned in a previous video, we know how to unscrew something. So I'm going to unscrew this battery tester and look inside. Maybe there's something broken. So I'm going to unscrew it counterclockwise or anti-clockwise, as I like to say. And I'm going to look inside. Maybe there's something broken. So once we take it apart, you can pry it open. This came apart pretty good. I open it up and there's all sorts of resistors and things to regulate the voltage. But I can see right away that this wire came apart from here. It's just plainly obvious that this just has to be re-soldered. Now I don't have my wire stripper with me, but there's enough metal left here for me to just heat it up and solder it back on. You don't want any of these wires touching each other because they could cause a problem later on. So what I'm going to do now is I'm going to turn on my gas-powered soldering iron here. This is easy peasy lemon squeezy, as they say. And I'm going to turn it on and it'll take me maybe a minute for it to heat up. I have solder over here and I'm just going to basically heat this up right here and just melt this back on. Be careful with solder. You should probably wear your eye goggles and wear gloves of some kind. But I'm not going to do that here. I'm just going to turn the soldering iron on. I think I'm out of gas. What a drag. I'm out of gas. I'm going to have to pause the video and fill my Benz-O-Matic up with gas. What a pain. I'm back in the set. So instead of filming, filling this up off the air, I'm just going to show you. Here's my Benz-O-Matic butane and you stick the little hole right on there and you just fill it up for a few seconds and you hear it starts like hissing and that means it's full. So I'm done with that. Now I should be able to light this thingamabob up and let this heat up. There's a little stand built in so you could not burn anything. So I'm going to turn it on. Now it's going. Now that's lit. I'm going to let that heat up for a minute. I'm going to get my solder ready. It's going to need a little bit. I don't need a whole lot. This is going to take like three seconds. I got my solder ready to go. Now while this thing is heating up here, you know, it would really be helpful to have a pair of helping hands there called. They're little because I only have two hands as you can see here and I have one, two, three, four points. So if I had a pair of helping hands, you can go Google those. You could see, you can get them anyway. They're little clamps that can hold things together. So I can use my two working hands and the two other hands. But I'm going to try and keep this close enough together so that I can. But what I want to do over here real quick is I'm just going to try and heat this up for a second and just melt some solder on there. A whole lot of it. And I have a few seconds before it gets cold. So there we go. The solder is melting. Now while that's melting, I'm going to take this wire here. I kind of ran into a problem here because now the two wires are falling apart, which is a pain in the ass. This is why you need helping hands. You should always wear safety goggles. So that seems to be connected now. It takes only like five seconds for it to cool. So I think there's a good enough connection there. I'm going to turn my soldering iron off. You should always have a wet sponge nearby to wipe the tip off, but I'm not going to do that now. I'll just wait till next time. Now the wire is properly attached. See I'm kind of sloppy when it came to doing that. I'm not a perfectionist. A lot of people are perfectionists. I mean there's a good benefit for being a little bit of a perfectionist because then you save yourself trouble later on. And I'm just going to stick this back on, make sure all the wires are hidden properly. And it seems like it's back together. This moves. We'll test it before we screw it back. Here's a battery. It works. See I fixed it. So that's it. I'm going to screw it back together. It's simple. It's just identifying what went wrong. This one was easy. Sometimes they're hard. Have a good day.
