Video Transcript for Tekonsha Trailer Breakaway Kit - Kit with Charger - 50-85-313 Review

Today we'll be reviewing part number 50-85-313. This is the Tekonsha Push to Test Breakaway Kit with a Premium Integrated Charger. Breakaway Kits are designed to bring trailers safely to a stop by activating the electric brakes so the trailer disconnects from its own vehicle during transit. Ideally, the safety chains would make that prevention but in some case this can be used as a last line of defense to bring that trailer to a stop in case it was to ever disconnect. In a lot of states this type of safety system is required for trailers that weigh more than 3,000 lbs so you definitely want to check into that to see if this would be a requirement for your application. The system features a push to test LED indicator here on the top. Once you push that green button, 1 of the 3 LED lights is going to eliminate so it's either going to indicate that you have a fully charged battery, a charging battery or that your battery needs a recharge. This breakaway system is for 1 to 3 axle trailers with electric brakes. The battery box has a battery inside that is included, so it's going to come with the battery box, the battery, all the wiring and the breakaway switch.

The only thing that you should need to purchase is the mounting hardware. It has an integrated multi-stage charger that's going to charge at the ideal charge current to quickly bring voltage up and extend the life of your battery. It has built-in Smart Adjust that changes to an ideal maintenance charge when the battery is fully charged. Once it is fully charged, the automatic float mode is designed to provide a continuous charge without overcharging. This does have a full charge green light that's going to indicate only when the battery is at 12.8 volts or higher. This does require a flat surface mounting. You can see that we have the mounting pattern here on the back.

The distance between our holes from center to center is going to measure 1" and going across is going to measure 5-5/8", center to center. Again, this is designed for up to 3 axles. The way that this mounts is you're going to mount the battery case to fit to the frame of your trailer with the breakaway switch cable towards the tow vehicle. The switch location should be selected to ensure unobstructed line of pull in the event of a vehicle separation. Then you can bolt the breakaway switch bracket to the frame of the trailer or case bracket using a 1/4" bolt and lock nut or you can use 2 individual 1/4" jam nuts. You want to be sure to wire everything per the instructions, those are included as well and they have really nice wiring diagrams that way you can be ensure that you're going to have a correct wiring situation and that everything is going to be wired correctly for your application. Then you can attach the breakaway switch cable to your tow vehicle frame being certain that the cable does not drive on the ground and that no restraint or restriction is placed on the cable itself. To go over the wires real quick, the wires that come from the switch both of them are going to be black wires.

One black wire is going to connect to the trailer brake wire and the other wire is going to connect to the blue wire from our battery box. It does not matter which black wire you use to make those connections; the switch really doesnt care and so you're going to be safe choosing either one of those black wires to connect to either the trailer brakes or the blue wire from the battery box. Here at the battery box we have a white wire which is going to be a ground wire and then we have the black wire that is our charging circuit wire and then we have the blue wire that goes to 1 of the black wires from the switch. To go over the measurements of each size, the switch itself, overall, from end to end, is going to give us a measurement of about 4-3/4" that does include the mounting location here with a pre-drilled mounting hole. It's going to stand at a height of about 7/8". The battery box is going to give us an overall width of about 6-1/4" to 6-1/2", somewhere in there that is including the mounting locations, the extension of the brackets here at the back. Overall height is going to give us a measurement of about 4" and then the overall depth is going to give us a measurement of about 4-1/2". That's going to do it for today's review of part number 50-85-313.

This is the Tekonsha Push to Test Breakaway Kit with a Premium Integrated Charger. .

Product arrived quickly and was as described. One feature I especially liked is the light indicating that the device is being charged when 7-way connector is plugged into the tow vehicle. Included installation instructions were same as on the etrailer website and were not very useful. Wiring diagrams for other than the breakaway device itself were difficult to decipher. The installation video on the etrailer website, however, was easy to follow and left nothing unanswered. 401598

I can only give this rating on the quality of the hardware because I never want to have to use it! Overall the product is well made with quality hardware components, a more than adequate sealed battery that came fully charged, and what appears to be 12AWG wiring where it needs to be to do the job the unit is intended for (lock the breaks in case of a breakaway). I bought this unit because I have a Tekonsha Brake Controller and I wanted to stay within the same product line. 194562

This was a great buy with the battery & charger included. If your main battery is dead this one keeps your breakaway switch active. You need this while transporting your trailer from your winter location to your summer storage area. 128692

- 50-85-313
by:

Great product. Looks great. Fairly easy to install. If using a junction box with this product you need to remember to hook one of the leads from the break away switch to the black wire as described. The other wire hooks to the blue break wire. At first I hooked to the blue from my truck, the blue from this battery pack, and the blue going to my brakes. After several hours of trying to figure out the error it threw on my brake contoller in my truck I took it to a trailer place where they had to do some trouble shooting of their own. They found that the lead from the break away switch needed to be spliced into the blue wire going to my brakes after the junction box to make it work properly. It can't be on the same terminal as the battery pack. Other than this little issue it has been great, hopefully I never need to find out how well it works on a run-a-way trailer! 92166

The plastic face plate on the top lid came off on the first one when I was washing off the trailer. It didn’t work after a little water got inside.

I have a 2015 GMC Sierra 2500HD Diesel, towing a 2017 Pinnacle 36FBTS 5th. wheel. The Pinnacle has a standard drum braking system. On a long trip this year I cracked both rotors on my truck from over heating related to the Pinnacle's drum brakes failing to fully provide proper stopping. I decided no more, and after much review I replaced the factory drum brakes with the Kodiak Discbrake system. (my first time ever doing something like this) In addition, one of the key items for me was a way not to replace my on-board factory trailer brake controller, (did not want to use an aftermarket product, that would diminish the interior look ) thus I also added the control Adapter Module that enabled me to use the factory installed brake controller. With all this change I decided to also go ahead and add a separate brake away battery. Everything I just described are shown in the attached photos. I found eTrailer extremely helpful in answering questions, although I did not have a lot of questions since their online videos proved most helpful. All parts of the Kodiak system worked fantastic following a 2500 mile trip. The improved braking is superior, and I did not need to replace my on board controller, but continued to use it by installing the control adapter. The disc brake picture is one of the disc brakes that I examined following our trip...all in perfect shape with everything working great for the entire trip. 610894

by:

This is a well-made product and was quite easy to install. The directions made the wiring simple. I especially like the test button on the top of the case, which lets you easily check the battery without opening the case. The case is a durable plastic, which allows some flexibility if you need to add another hole or two to match your current mounting bolts. After 3 years of use, the battery and housing have held up fine. 584541

  • Troubleshooting Locked Brakes on 2013 Forest River Salem Travel Trailer

If it does, I recommend Electric Trailer Brake Kit # AKEBRK-35-SA, which are self-adjusting brakes that are designed to work with 3,500 lb axles.

  • Electric-over-Hydraulic System Recommendation for a 15K Trailer with Disc Brakes
  • For your 15,000 lb toy hauler, I recommend the HydraStar Actuator, # HBA16, that you referenced. The response time for this actuator from activation to full pressure is 1.2 seconds and it is compatible with the integrated brake controller in your 2012 Ford F-250 Super Duty. This actuator is also made here in the United States. This actuator is designed to be used with the industry standard 12 volt, 5 amp-hour breakaway battery. If you do not have a breakaway system, then I recommend...

  • No Brakes On Trailer When Pin Is Pulled On Breakaway Switch
  • I have attached a couple of helpful articles that explain how to install and test breakaway systems. I spoke with my contact at Hopkins and they told me that the light should not illuminate unless the cable has been pulled. Since you said the light is blinking when hooked up, it sounds like there may be a problem in the wiring. You can also test the battery to make certain it has a full charge. If you do not have the breakaway system wired correctly, the brakes may not be getting the...

  • Trailer Breakaway System Recommendation for a Tri-Axle Trailer
  • If all 3 of the trailer axles have brakes you will need one with enough amperage to be able to apply the trailer brakes on full for at least 15 minutes. The Tekonsha system, # 50-85-313 will work with 1 to 3 axles. I have included a link to a video review for you. Another option is # 2028. I have also included a link to an FAQ article on installing a breakaway kit.

  • Battery on Tekonsha Trailer Break Away System not Receiving Charge
  • I would begin by testing the 12-volt accessory power circuit pin on the tow vehicle 7-way connector using a circuit tester like part # 40376. The 12-volt accessory pin is in the 2:00 position in the connector socket as shown in the provided photo. If you are not showing power on that pin, how to proceed next will depend on the year, make and model of vehicle and whether or not the 7-way is factory or aftermarket installed. If the 7-way is factory installed, the fuse is most likely protected...

  • Installation Instructions for Breakaway Kit Part # 50-85-313 and Trailer Wiring Junction Box # 38656
  • The wiring for the Tekonsha breakaway kit # 50-85-313 and trailer wiring junction box # 38656 is listed below. You can also view the picture to the right. The breakaway kit will have 3 wires to hook up where as the breakaway switch will have 2 wires. Take either brake switch wire and connect to the blue wire from the battery box. The other switch wire is output to the trailer brakes. White is ground and black will connect to the 12 volt circuit from the 7-way connector. The trailer...

  • Converting Military Trailer W/ Air Assist Hydraulic Drum Brakes to an Electric Over Hydraulic System
  • From a price, performance and reliability standpoint, I would recommend the Carlisle HydraStar Electric Over Hydraulic Actuator for drum brakes, part # HBA-10. You would also need a breakaway kit like the # 50-85-313 offered by Tekonsha as well as an in-cab brake controller that is electric over hydraulic compatible, like the Tekonsha Prodigy P2, part # 90885 or the P3, part # 90195. Both controllers are electric over hydraulic compatible, but the P3 is a bit more user-friendly for those...

  • Recommended Parts For Changing Surge Coupler To Electric Over Hydraulic Disc
  • When changing your trailer over you will need to do the complete change at one time since some of the parts are made for specific type brakes. I have attached a drawing that shows how the Titan BrakeRite EHB Electric-Hydraulic Actuator for Disc Brakes, part # T4813100 is attached. The # T4813100, has 5 wires that are blue, black, white, brown and purple. You will want to splice the blue wire from the adapter to the blue wire from the actuator. This allows the adapter to intercept the...

  • Is a Diode Needed to Prevent Backfeeding from Trailer to Tow Vehicle
  • There is a possibility of back feeding but this should not really be of a concern as the odds of it happening are slim to none. If you did choose to use a diode then you would need one rated for the components it would be powering. The highest rated diode we carry is the Roadmaster Single Park Light Diode part # RM-690 which is rated at 85 amps. There are a few things you will need to take into consideration for your winch and breakaway system. For starters, it is not advised to run...

  • Disc Brake Conversion for 5th Wheel Trailer with 8-Lug/12-Inch Hub/Drums and Tandem 6K Axles
  • Converting a 5th wheel trailer from electric drum brakes to electric-over-hydraulic disc brakes will require a couple of items: the disc brake kit of hub/rotors and calipers, a brake line kit, an electric-over-hydraulic actuator, a breakaway kit and a brake controller such as the excellent Prodigy P3 # 90195. The linked article covers each of these items and is a good starting point for planning your project. A link is provided that will show you all disc brake kits with the 8-on-6-1/2-inch...

  • Breakaway Battery Recommendation for Triple Axle Trailer
  • I have a couple of breakaway battery kit options for you, but the Hopkins Engager Trailer BreakAway Kit # 20400 is not compatible with your triple axle trailer. The # 20400 is only designed for use with single and tandem axle trailers. For your triple axle trailer, you will want to use a breakaway battery that is designed to work with triple axle trailers. I recommend using the Tekonsha Push to Test Breakaway Kit with Premium Integrated Charger # 50-85-313 because it has the same great...

  • Switching from Hydraulic Surge Brakes to Electric Over Hydraulic Disc Brakes on a Boat Trailer
  • First, you may not need to replace the coupler at all. In most cases you can still use the surge coupler it just won't actually do anything with the brakes after switching to electric over hydraulic. And its even better if you are able to lock out the actuator so you don't get the clunking of the actuator during starts and stops. Since you have a Maxbrake brake controller I would go with the Carlisle HydraStar, # HBA16, since it is confirmed to work with that brake controller without...

  • Availability of Chargers for Trailer Breakaway System Batteries
  • We carry a Trailer Breakaway Kit Battery Charger that would be perfect for you, the part # is 20011. The black wire connects to the 12-volt power from the trailer connector, the red wire connects to the positive battery terminal on the breakaway battery, and the blue wire connects to the breakaway switch. This would be the easiest, most economical way of providing battery chargers for the breakaway systems on your various trailers. You will want to make sure that the batteries are...

  • Parts Needed to Add Electric Drum Brakes to 1996 Pop Up Camper
  • Unless your axle is in bad shape or it uses a weird set of bearings and seal you shouldn't need to replace it just to swap your hydraulic brakes over to electric.We actually have everything that you need for this conversion. To replace your older size 20.5x8-10 tires/wheels I recommend the Kenda 205/65-10 Bias Trailer Tire with 10" White Wheel # AM3H410 if you need the tire and wheel or part # AM1HP54 for just the tire (which is the current size listing of your tire size). This has a load...

  • Parts Needed to Install Electric Brakes on a 2007 Kaufman Car Hauler Trailer
  • To change from hydraulic brakes to electric you need to swap out the brake assemblies, add trailer wiring for the brakes, add an electric breakaway kit, and then make sure your tow vehicle has a brake controller installed. I'm not sure what the weight capacities of your axles are but that is how you will decide which brake assemblies to buy. For 3.5K I recommend the kit # AKEBRK-35-SA, for 5.2K I recommend the kit # AKEBRK-7-SA, and for 7K I recommend the kit # AKEBRK-7-SA. All of these...
