How to Install the Tekonsha Push-To-Test Trailer Breakaway Kit

Hey there trailer owners, today we'll be taking a look at, Tekonsha's push-to-test trailer breakaway kit with built in battery charger. And what's cool about this battery here is that there is a charger that's inside, that helps limit the charge to it so that we don't overcharge this battery. And it also provides you with an indicator here, so you can verify before every trip and ensure that this battery is charged up. So that way you are protected in the event that disconnect. We just hit our button there and it'll show us whether or not we're fully charged, which we currently are. There's also an indicator that will light up here when you have your truck hooked up and when it's running.

That tells us when it's charging the battery and we have a red indicator there that will let us know when we need to recharge the battery when it has been discharged.I do believe that comes on at about 80% discharge. And with this system here, you're going to get a separate battery for your breakaway switch. And what's nice about that is that you can isolate this battery. So that way, this batteries only job is for your breakaway event. So you can be certain that if you we're to have that unfortunate event, that you are prepared for the worst with this.

If you have other batteries on your trailer, like the one we have here, yes, you could hook your breakaway switch to it and it probably will work in a lot of instances, but if you're using your trailers functions that uses those batteries and those batteries happen to become discharged because of what you we're using them for. Whether if you run in lights or operating the dump trailer, like on this one here, then it may not be able to apply the brakes if those voltage are too low on those batteries.So having this one here all by itself, dedicated just to this circuit is going to keep you safe. Now when installing this with additional batteries like that, with an additional battery bank, I do recommend having a battery isolator to ensure that the auxiliary batteries you got aren't discharging, charging this battery up when you're not using your trailer. We have a lot of different battery isolators here at On our dump trailer, we're using Redarc's, BCDC charger.

This not only isolates the start battery from our truck, but it's isolating our breakaway battery from our auxiliary batteries here. And it's also works as a charger to ensure that these auxiliary batteries, when we're driving down the road, get charged up to 100% charge. On top of our battery, we do have status indicators to let us know the state of charge, whether it needs to be charged and if it is currently charging. Now we've gone over some of the features of our breakaway systems, battery and switch.Why don't you follow along with me And we'll get it installed together. So you can have the confidence to do it at home.

We'll begin our installation by mounting the major components. We just have two here. We have our battery box and there's four holes that hold it on. You can either use self tapping screws if you're just going to be running it into the frame. Since we mounted it inside of this storage compartment here at the front of the trailer, it's got kind of a thin wall so, went with this one to make it look nice. And due to the thinness of the wall, we decided to use a nut and bolt with this particular one here. But you can get self tapping screws here at etrailer If you need them, or you can get hardware from your local hardware store if you want to go with an option like this. And then you want to Mount your breakaway switch, we just mounted this using a self-tapping screw.I did go ahead and put a fender washer on it just because it allows the breakaway switch to have a little bit of movement, just so that way we can ensure it's going to pull straight to pull our pin out. We don't have any binding or anything on it. Once you've got these two components mounted up, we can now wire it up. We'll have two wires coming off of our breakaway switch and there's three wires coming off the box. We'll start here at the breakaway switch. The two wires can hook up to either of the circuits. So they're both black that's why they're not really color-coded. So one of those wires needs to hook to your brake circuit, which is typically a blue wire coming off of your seven way and that's for your trailer brakes. And then the other wire here is going to connect to a power source, which in this case is going to be the blue wire coming off of the battery that we just mounted.So I do have a white wire here that I use just to extend it inside to where we can make the connection at the battery. To make this connection we just use some heat shrink butt connectors, which are available here at etrailer. Once you crimp it down on each wires, after stripping those back, you'll want to use your heat gun to shrink them down. And that's going to seal them up to ensure a long-lasting connection. So here on the inside, you can see this is the white wire that was connected to our breakaway switch here. It goes to the blue wire on our battery. This is for the output for the breakaway switch so, in the event of that pin gets pulled this sends power out, the breakaway switch completes the circuit, and then sends that onto your trailer brakes, to turn them on, to help your trailer come to a safe stop.The other two wires coming off of our battery, or just power and ground. The other wire here, this power. This is for charging this battery, and we want to hook this to the charge circuit on our seven way, which is typically a black wire, and that's ratted up here. We did use a 20 amp circuit breaker in between, just to protect ourselves in the event that there are any shorts or something. The breaker can then open and it's an automatic resetting breaker so, once you fix the issue, it will reset itself and then you can start charging, once again. We have these available here at etrailer, and usually I use self-tappers to Mount these, but again, we use the nut and bolt due to the thinness of the metal, and for cleanliness. You can also get ring terminals here at, for hooking up your wires to the circuit breaker.So it's just battery circuit breaker. Other side of circuit breaker goes to our seven way. The bronze post is your seven wayside and the silver post is your battery side because, this is our load cause we're charging this battery. And then the last wire is our white wire here. This just needs to go to ground, so this just runs down. I extended it with some additional white wire. If you need additional wire, you can also get that here at etrailer. And we just go down and then we use a self-tapping screw and a ring terminal to just run it right into the frame, so that way we've got our ground there too. And it's important that you've got it grounded here to the frame because, when the breakaway pin pulls, it sends power through that switch to your trailer brakes, but that circuit needs to be completed to get to ground back to our auxiliary battery, our breakaway switch battery, we just added here. So looking into the frames, is going to ensure that we are grounded. And that completes our look at Tekonsha's push-to-test trailer, breakaway kit with built-in battery charger.
