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

This product was just received, but it appears to be well made. Instructions were very clear, however I would suggest marking your trailer wire with colored tape prior to removing the original breakaway battery to avoid confusion. In my case I did not want to drill additional holes in my trailer tongue due to the different configurations of battery box mounts. Angela wit etrailer matched up the hole pattern within a few minutes and solved my issue. 805021

Nice kit that provides what you need for a break away system. Note that it comes with a switch -- you don't need to buy a separate one (as I did, ahem). Mounts easily enough. I kinda wish the wires had been longer and the box was waterproof (or look like it would readily survive a rogue wave), but I just extended the wires myself and I'll be careful around water :) 798875

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

  • How do You Test a Trailer Breakaway Kit After Installatiion
    To test a trailer breakaway kit like Tekonsha Push-To-Test Trailer Breakaway Kit part # 50-85-313 you will simply lift your tires off of the ground one at a time and pull the plunger out of the brake away switch. When installed properly the tire off of the ground should not spin if you try to turn it. Repeat this for each wheel and that will ensure that the breakaway kit is working and also confirm your brakes are working properly. Let's say you did this and one wheel would turn while the...

  • Can a Trailer Break Away System be Tested with Trailer Connected to Tow Vehicle
    You should always disconnect the trailer before testing a break away system, including # 50-85-313. Testing the system in this case means pulling the break away pin from the switch. The resulting charge from the break away battery could lead to back feeding on the brake output circuit back to the controller. Some controllers have built in circuit protection to prevent damage to the controller. I would need to know the make and model of the controller to determine if it has that feature. You...

  • Comparing Tekonsha Trailer Breakaway Systems
    Tekonsha breakaway kit # 50-85-313 is an all-in-one type of set up in which the charger is integrated into the lid of the battery box. Kits # 2028 and # 20020 both have a separate external charger that is, to put it bluntly, better than the one integrated into the lid of the other kit. They are all good options though and I am certain you would be happy with any of the 3. I have included links to videos for all 3 kits for you.

  • How Long Will Battery Last for Tekonsha Push-To-Test Trailer Breakaway Kit
    Without being used the 12V battery included with the Tekonsha Push-To-Test Trailer Breakaway Kit # 50-85-313 will start to lose charge at around 6 to 8 months. At the year mark it will fall below nominal charge and at 1-1/2 to 2 years it will be completely dead and would need to be jumped. When installing the breakaway kit you will want to run the black power wire to the 12V circuit coming from the trailer's 7-Way so that the battery can maintain its charge during travel.

  • Troubleshooting a Breakaway Kit that Applies Voltage on Trailer Brakes All the Time
    It sounds like you may have wired your setup in such a way that the battery is somehow putting voltage on the brake output circuit which is why your brakes are locking up. Check the third page of the installation instructions I attached to see the wiring diagram on how it should be wired up and compare it to your setup. You should also check to make sure that the plunger is properly installed into the switch.

  • Can a Parking Brake or E-Brake Be Added to Dexter Electric Brake Assemblies
    A parking brake system, also known as an e-brake, can only be used if the brake assemblies are already equipped with a parking brake. Dexter does offer electric brake assemblies with a parking brake, but their standard electric brakes assemblies cannot have a parking brake added to them if they were not already properly equipped. You can tell if your brakes are equipped with a parking brake by looking at the backing plate. There will be an actuating lever at the top of the brake assembly...

  • The Correct Breakaway Kit Battery Size to Use on a Trailer
    Using the house battery on your trailer will provide a 12-volt power to a breakaway kit, but is not recommended. A Breakaway Kit, like # 50-85-313, is designed to stop a trailer that has come uncoupled from a tow vehicle. This kit relies on the power of the battery to activate if a trailer is comes uncoupled. Manufacturers recommend that you use a dedicated power source on the breakaway switch to make sure that there can be no outside draw or interference on the breakaway circuit. There...

  • Are Trailer Breakaway Kits Universal in How they Install
    Yes, our trailer breakaway kits like the Tekonsha Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger # 50-85-313 are universal.

  • Troubleshooting Trailer Lights Not Working on Gooseneck Trailer
    If the truck wiring is working with other trailers then the issue is definitely on the trailer side. Although the hitch ball does provide an extra ground source, you do not want that to be the main ground for your trailer wiring. You should have a main ground wire somewhere that is connected to a clean, bare-metal surface. If this is not the case then that is the culprit and you need to fix it. The ground wire can be found and traced from the pin in the 5 o'clock position on your trailer...

  • Will Built-In Charger in Tekonsha Breakaway System Over Charge the Battery
    The Breakaway Kit with Premium Integrated Charger # 50-85-313 should not overcharge the battery in the system. It will go into a maintenance mode to maintain the optimum charge after the battery is fully charged. A battery being charged will get hot depending on how much it needs to be charged. It is best to charge the battery while towing or while the vehicle is running so the maximum amperage is being pushed back. This will reduce the time it takes to charge the battery. Charging...

    Check out the wiring diagram I attached, I think that will make more sense for you. There are 3 wires coming off of the breakaway battery as you indicated. The black wire will tie into the 12 volt hot lead from the trailer connector. This will provide a trickle charge to the breakaway battery while you are towing. The white wire should be grounded to the main trailer ground and the blue wire will connect to one of the leads from the breakaway switch. This wire will send power to the...

  • How Long Should a Trailer Breakaway Cable Be
    The best length for the cable of a breakaway system like the Tow Ready Trailer Break Away Kit # 50-85-313 that you referenced will be just a bit 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 which will bring the trailer to a stop.

    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.

The highest rated diode we carry is the Roadmaster Single Park Light Diode part # RM-690 which is rated at 85 amps.

  • Troubleshooting Weak Trailer Brakes and Breakaway Switch that Doesnt Work at All
    It sounds like you need to check the trailer braking system out. I would start by making sure that the connectors on the vehicle and trailer are connected properly, and that there is no corrosion in either of the connectors. Corrosion can rob power from the trailer brakes especially because the trailer brake circuit is in the lower position in the connector and next to the ground wire. Using some dielectric grease, item # 11755, in the connection can often help a great deal. Make sure...

    There is a way to bypass the breakaway system of your trailer but I would only recommend you do so to get your trailer to a dealer so that it can be fixed. If you were to get pulled over and the breakaway system was to be tested you would get in trouble. To simply bypass the system you would just need to cut the wire that goes from the switch to the brake output circuit of your trailer wiring.

  • How to Charge a Trailer Battery
    The Tekonsha Push to Test Breakaway Kit # 50-85-313 that you referenced is designed to charge a breakaway battery. It would not charge your trailer battery that you use for accessories. To put a maintenance charge on your trailer battery that runs accessories you would need to run a wire from the 12 volt accessory circuit of your trailer connector to the positive post of the trailer battery. This won't charge a dead battery though, it will just help keep a charged battery topped off. To...
