Video Transcript for Pro Series Breakaway Kit Installation

Today on our Gooseneck flatbed utility trailer, we'll be installing the Pro Series Push-to-Test Breakaway Kit with Premium Integrated Charger, part 50-85-315. We'll begin up here at the front of the trailer. We're going to need to mount our battery box that has the integrated charger built into it as well as our breakaway switch. Now, there's already a couple of holes in this trailer as it previously had a breakaway switch installed. We drilled out a hole for the ground, and we drilled out the hole a little bit bigger to mount the breakaway switch to it as well as a larger hole to allow our wires to go through the frame. We'll also have to drill 4 additional holes to mount the battery box with the integrated charger in it to the side of the frame. Now, we'll go ahead and hold our battery box up into place. We'll mark the location of each of the holes that will need to be drilled.

Now that we have the 4 locations that we need to drill the hole to mount the battery box marked, we'll go ahead and set the battery box aside. We'll then take a 1/4-inch bit and drill the 4 holes out. Now that we have all of our holes drilled, we'll go ahead and begin here by mounting the breakaway switch. To mount it, we're going to use a 1/4-inch bolt with a locking flange nut. We'll go ahead and secure that to the frame of the trailer. With that done, now we're ready to mount our battery box.

To mount the batter box, we'll be using four 1/4-inch bolts, again using locking flange nuts. Now that we have our battery box mounted, we're ready to go ahead and connect some wires. The white wire coming off the battery box will be a ground wire. Now, to make our ground connection with the white wire here, we're going to use a ring terminal, which is part number DW05705-1. We'll go ahead and strip our wire back to make our connection to the ring terminal. Once that's done, again, we'll go ahead and use another 1/4-inch bolt with a locking flange nut. Now, you notice that there's 2 more wires coming off of the bottom of the battery box.

One of them is black that will need to run to a 12-volt power supply that comes off the 7-way of our vehicle. Now, this trailer has a junction box, so we'll be tying into that a little bit later. Now, the blue wire coming out the bottom of the battery box will need to tie to one side of the breakaway switch. To make these connections, we'll be using heat shrink butt connectors, part number DW05744-5. Then, the other wire on the breakaway switch will be tied in with the wire that runs back to the brake circuits. Again, we're going to tie into a junction box on this particular trailer.

Now to run the black wire as well as the connection off of the breakaway switch back to our junction box, we'll be using some jacketed wire that's part number 12-2-1. Now, depending on where your junction box is located on your trailer or how your trailer is wired will depend on the length of wire needed here. To make these connections, we'll be using heat shrink butt connectors, part number DW05745-5. Once our connections are made, we'll go ahead and use our heat gun to seal up the butt connectors. Once we've made our connection to the breakaway switch, we'll wrap that connection and the blue wire connection up with some electrical tape. Now, we'll take the other end of our double-bonded wire and connect it to the black wire from the battery box, again using the yellow heat shrink butt connectors. Now that we have all of our wire connections made, we're going to go ahead and take a piece of 1/2-inch wire loom and put it over the wires to give them a little extra protection here. The 1/2-inch wire loom is part number 459075-1 and can be purchased by the foot. We'll also be using a few zip ties up here to help secure off any excess wire. Now that we have our wire connections made up here at the front, we're ready to route the jacketed wire back to our junction box, which is located just underneath the bed of the trailer. Now, when routing the wire back to the junction box, we'll use some zip ties to help secure things as well as some 1/4-inch loom clamps to help secure it to the trailer. The 1/4-inch loom clamps are part number A0250. Again with these loom clamps, we'll be using 1/4-inch bolts and locking flange nuts. Now that we have our jacketed wire routed down to our junction box, we're ready to make the connections here. We'll take our double-bonded wire, cut into it, and remove some of the sheath to expose our wires. Then, we'll route them into our junction box. We'll first strip back the white wire and add a ring terminal, part number 44-5310A. The white wire will tie in with the brake circuit in the junction box. Next, we'll strip back our black wire and add a ring terminal, and it attaches to the 12-volt accessory circuit. Now that we have our connections made, we'll go ahead and button back up our junction box by putting the cover back on it, and then, we can go up to the front of the trailer and test it out. Now, we'll be using our tester. When the 12-volt power supply is on and it's showing it's charging, you'll get a yellow light. If it needs a recharge, you'll get a red light, and if the battery is fully charged, you'll get a green light. In our case, the battery is not fully charged, so we get a red light. When you remove the 12-volt power supply, it goes back to blank, and with that, that's all there is to it to installing the Pro Series Push-To-Test Breakaway Kit with Premium Integrated Charger, part number 50-85-315, on our Gooseneck flatbed utility trailer. .

Nice product but poor packaging by trailer. Product arrived damaged and since I needed to use my trailer the next day, I repaired it myself. Etrailer should have place the thin product box inside a better shipping box. They may have saved cost on their end but now have an unhappy customer. 195255

I have been having trouble with my trailer brakes and noticed that the existing battery was no longer bolted to the trailer, but was loose in the storage compartment. Since it was several years old I decided to replace the whole system. The new one has a charging system , which will keep the battery charged. I will have to do some rewiring,but that will not be a problem. Thanks . This looks like a good system and i can't wait till I get some good weather to work on the trailer. 592301

Ask the Experts about this Pro Series Trailer Breakaway Kit

  • Can Breakaway Battery Be Submerged on Boat Trailer
    The battery/battery box for the Pro Series Breakaway Kit # 50-85-315 that you referenced (along with most other units) is weatherproof meaning it's designed to be mounted outside and can handle exposure to rain and splashes but it's not waterproof. Because of this I don't recommend actually submerging this or any other breakaway battery for even a short period of time. I know it will mean moving it to a less convenient location but I highly recommend mounting the battery in a higher...

  • Troubleshooting Trailer Breakaway System that Says its Not Chargin
    Test the 12 volt power wire that feeds the charging circuit for the breakaway kit part # 50-85-315 that you have installed on your trailer with a circuit tester like part # PTW2993. You should be getting 12 volts running into the battery box that will be providing the battery with a maintenance charge. You can also test the wiring leading to the battery from the lid with it disconnected from the battery to see if there is voltage there. If so, then the lid of the box must be defective...

  • Troubleshooting Trailer Brakes that Are Activating but Not Stopping Trailer
    Sounds like you installed new brakes and they aren't wanting to grab and stop your trailer. Most likely you just need to adjust the assemblies so that they will actually grab. If they are self-adjusting brakes all you would need to do is make several brake applications with the trailer moving and they will set themselves. To see how to manually adjust trailer brake assemblies check out the video I attached, fast-forward to the 4:35 mark of the video. I also attached a help article...

  • Do Trailer Breakaway Systems Usually Power from Separate Trailer Battery
    Typically breakaway systems on trailers like yours will be powered from a separate smaller battery than the two larger ones you have on your trailer. You can trace the wiring of the switch back to see where it ends, but typically the breakaway system is in a box that is somewhat near the nose of the trailer. I attached a chart that shows how a breakaway system usually wires up as well. I also attached a help article on trailer breakaway systems for you to check out as well.

  • When Would a Trailer Break Away Kit Be Required By Law
    Many states in the U.S. and provinces in Canada require break away kit. In order to determine the specifics for where you live and where you plan to travel, you can check with the state and federal departments of transportation for the area. Specific weights or trailer types may change from state to state, so it is important to check for every state in which you plan to be towing. A break away kit is just a good idea in general, whether it is required or not. It is a fairly simple system....

  • Can a Trailer Be Pulled With a Faulty Breakaway System
    The trailer breakaway's are required in most states so I cannot advise for you to continue traveling without having the system repaired or replaced. It sounds like you have already identified the culprit (shorted wire) so what I recommend is just ordering a new system that way you can get it installed and hit the road again as soon as possible. The Pro Series Push to Test Breakaway Kit pprt # 50-85-315 is what I recommend for this because it is cost effective and easy to install. That said,...

  • Trailer Brakes Work with Break Away System But Not with Brake Controller
    It sounds like the brake controller might need to be reset or the wiring from the vehicle side to the break away system needs to be examined. Try adjusting the power output of the controller. If that does not work you can test the controller itself using a circuit tester like # 40376 if needed. Sever the blue wire a few inches from the back of the controller and use the circuit tester to test the end coming from the controller while applying the manual override. If it does not show power...

  • Length Of Safety Cable on Trailer Breakaway System Recommendation
    The best length for the cable of a breakaway system like the Tow Ready Trailer Break Away Kit # 50-85-315 that you referenced will be slightly longer than the safety chains. The breakaway cable should be longer than the safety chains according to RVIA Recreational Vehicle Industry Association. This will activate the brakes in the event you lose the trailer connection and the safety chains fail.

  • Parts and Installation of Trailer Breakaway Systems
    Yes, a towed trailer that has brakes must also have a functioning breakaway switch/battery system so that in the event of an accidental uncoupling of the vehicle and trailer the brakes on the trailer will receive direct 12V power from the breakaway battery to stop the trailer. We do sell replacement switches like # 2005-P, complete kits like the item # 50-85-315 that you referenced and replacement batteries like # C52023. Switches are NOT specific to any particular brand of breakaway...

  • Do All Trailers with Electric Brakes have to have a Breakaway System
    No, but your local and state laws may require one. You will need to check anywhere you will be towing the trailer to determine if a breakaway system is required by law. They are also just a good idea in general because they will stop a run away trailer should it get disconnected from the tow vehicle. We have several different breakaway options which I have linked to the right. I have also included a link to our help article on breakaway systems for you.

  • Where Does the Cable for the Break Away Switch Attach on the Tow Vehicle
    The cable loop for the breakaway switch in the Trailer Break Away Kit With Built-In Tester and Battery Charger, # 50-85-315, does not attach to the ball. Run the pin through a safety chain loop on the hitch. Pass it through the loop on the other end of the cable, and then plug it in to the break away switch.

  • Breakaway System Kept Trailer Brakes On and Melted Wiring
    The way that a breakaway system for electric brakes works is when that pin is pulled it completes the circuit between the breakaway battery and the brakes. They have to stay on full for at least 15 minutes to be legal. But there is nothing stopping the brakes from staying on after that 15 minutes is up. Usually breakaway batteries are 5 amp hour rated. For 10 and 12 inch brakes each magnet draws between 3.2 and 4 amps. So if you have 4 brake assemblies that would be 12.8 to 16 amps....

  • Weak Trailer Brakes After Pulled Breakaway Pin and Burning Smell
    I have attached a photo of how a breakaway system should be wired. If you would please, check the brake output wire on the trailer where the breakaway switch is spliced in. This is shown as the letter A in the attached photo. If something were to fail on the breakaway system then it would more than likely be the switch, not the pin. Since you said you smelled burning I would replace this anyhow with part # 2005-P which also comes with a new pin. With that being said, I suspect that...

  • Where to Attach the Electric Brake Emergency Break Away Cable When Towing with a Fifth Wheel Hitch
    There are many options for attaching the breakaway cable from the Tow Ready Trailer Break Away Kit, item # 50-85-315, to your vehicle. You could attach to a tie down point in the bed of your truck or you could use stake pocket tie down and attach the cable to it. You could also run the cable down to the safety chain loop on the bumper hitch if your vehicle is so equipped. Finally, you could attach the cable to the rails installed in the bed of the truck.

  • Recommended Charger to Maintain Trailer Breakaway Battery
    The battery in a trailer breakaway kit such as Pro Series # 50-85-315 will not hold a charge for a full 6 months of storage, especially if we are talking cold-climate storage. The best way to keep the battery in good shape for off-season storage is to bring it inside and keep it on a charger/tender like the CTEK charger # CTEK56353. I own and use one of their chargers continuously, 24/7/365, on the various batteries in my vehicles, mower and motorcycle, and it works great to keep them...

  • Is a Current Limiter Circuit Breaker Needed for a Battery Charge Line
    It sounds like you have a charge line ran from the RV's battery to the trailer's battery. If this is the case then yes, you will need a current limiter (circuit breaker) in between the two in order to prevent any spikes that could in turn damage either battery. In the charge line kits we offer like the Roadmaster Battery Charge Line Kit part # RM-156-25, they come with a 15 amp circuit breaker so that is what I recommend you use. However, this battery charge line is only going to provide...

  • Can Push to Test Breakaway Charging Light be Turned Off When Trailer is Connected to Tow Vehicle
    As long as the trailer is connected to the tow vehicle and the battery isn't fully charged the single yellow LED charging light will be on. This is because the 12 volt circuit is always active in the vehicle side trailer connector. The single LED light draws such little power that it would likely take weeks if not longer of it just sitting with that light on to drain the battery. Bit there is a way that you can remove power from the 12 volt circuit when the truck is turned off. You...

  • Brake Controller Does Not Detect Trailer when Breakaway System is Connected
    The most common issue with breakaway systems occurs because of the wiring. They do not always make it as straight forward as it could be. Starting from the trailer side connector the brake output wire will go to the brakes and to the breakaway switch. The other wire from the switch will go to the brake output wire on the breakaway battery. The power wire to charge the breakaway battery will connect to the 12 volt wire from the trailer connector. And the battery ground wire should be...

  • Should Charge Light Stay Lit on Tow Ready Breakaway System when Disconnected from Tow Vehicle
    No, the charging light on the Tow Ready breakaway system should turn off if it is not getting a charge from the vehicle. If it stays lit up that could indicate a short somewhere that is drawing power. It could be due to corrosion in the trailer side connector. Make sure the trailer side connector is clean and free of corrosion inside and out. Check all connections for any loose or pinched wires/connections or frayed wires that might be touching bare metal. It could also be a ground...

  • Troubleshooting Trailer Breakaway Switch Where Wiring Causes Light to be Yellow all the Time
    I believe the problem is the connection of the switch on your breakaway. You said you went from blue brake output on the trailer to the blue wire of the switch and then on the other side of the switch you went to a black wire. You should have went to the blue wire of the battery box. The black wire of the battery box goes to the 12 volt power of the 7-way which is typically red. Check out the diagram I attached for more info as well.

  • What are the DOT Requirements for Trailer Breakaway Systems for Miltary Trailers
    I can certainly help. You will want to look at DOT/FMCSA regulation 393.43, specifically paragraph (d). This regulation should have everything that you need for what the Navy requires. In general, a breakaway system needs to be sufficient enough to apply the trailer brakes on fully for at least 15 minutes.

  • Can Pro Series Push to Test Breakaway Kit Install on Boat Trailer
    None of the breakaway battery boxes we offer are going to be water tight but the Pro Series kit part # 50-85-315 that you referenced is reasonably water resistant and would do a great job on a boat trailer. Do your absolute best to install it where it won't get submerged. I attached an install video for this for you to check out as well.

  • Breakaway Kit Recommendation for 2006 Fleetwood Trailer
    Breakaway kits are universal since they all install on trailers in the same way. They are required too by law so you will want to install a kit on your 2006 Fleetwood like the # 50-85-315 which is our most popular and highest rated. I attached an install video for this kit for you to check out as well.

  • Can Trailer Breakaway Kit Use Battery of Trailer
    DOT really will only care that the breakaway system battery will be capable of holding the trailer brakes fully engaged for at least 15 minutes at any given time. It's wiser to use a dedicated battery for this so that you don't deplete the main trailer battery with other accessories and then when needed it not be able to fulfill it's duties to stop the trailer. I'd recommend using a kit like the part # 50-85-315 that you referenced which includes a dedicated battery.

  • Dead Batteries from Accidental Tripping of Trailer Break Away
    Yes, it is indeed likely that your trailer breakaway batteries were depleted from the accidental tripping of the breakaway switch (but good for you for doing the yard work!). If your main trailer batteries have a charge line to feed the breakaway battery then they could have been depleted as well. Breakaway batteries are required to be able to apply full braking power (in the event of a disconnect) for about 15 minutes; this may vary slightly depending on the particular system and the number...

  • How to Tell if Breakaway System Came On After Pulling Trailer with Breakaway Pin Pulled
    If you were dragging the camper you would probably have noticed. The tires would also have flat spots. But if the brakes were worn and not adjusted out then the tires could have kept rolling. The drums though would have been extremely hot and you would likely see discoloration on the armature surface in the drum (the armature surface is where the brake magnet makes contact with the drum). It is also possible that the breakaway system didn't do anything. That could happen because of a...
