Video Transcript for Tekonsha Trailer Breakaway Kit - Kit with Charger - 20020 Review

Today we're going to be taking a look at the Tekonsha breakaway kit with charger. This kit features a rechargeable, sealed maintenance free battery with charger for trouble free towing. Now break away kits are designed to bring trailers safely to a stop by activating the electric brakes should a trailer disconnect from the tow vehicle. Now ideally your safety chains that connect the trailer to the tow vehicle will prevent a trailer from disconnecting if the coupler comes off the ball but in the event where the safety chains fail the breakaway kit acts as a last line of defense against a runaway trailer. Now this type of safety system is required in most states for trailers weighing more than 3,00o pounds. The breakaway kit is going to work with 1, 2, 3 or 4 axle trailers. It's going to feature a weather and corrosion resistant design.

As you can see it's a really nice compact unit. You're going to have the nice durable case right here and inside is going to be the sealed maintenance free, 5 AMP, 12 volt battery. The unit also comes with your battery charger. This unit is like a triple charger and it fits securely into the breakaway battery case so there's a slot here in the back for the charger to sit. It's going to provide a continuous recharge and it's designed so that it doesn't permit the battery to overcharge.

So that's a nice safety feature of the unit as well. On the charger your going to notice that it has 4 wires. These 2 right here, it's going to have a tag on it. It says those go to the primary battery. The other 2 have another tag on it and those say that it goes to the breakaway battery. So that's going to be really easy to get connected.

To get installed. The unit also comes with detailed installation instructions to help walk you through the entire process step by step. The breakaway switch is this component right here. This is a nylon switch, 2 wire design and it's going to have a coated steel cable right here. It's like a braided steel. This unit mounts to the trailer frame.

It's going to have your mount hole right there. Hardware not included. Switch or the actual plug is right here so this cable connects to the tow vehicle and then when it comes to wiring the unit, one wire goes for power supply. The other wire splices to the brake output from the trailer brakes. Interchangeable wire design means that it does not matter which wire goes to which function. It will work the same either way. The unit is going to feature a nice wide operating temperature. So it will operate down to negative 76 degrees Fahrenheit all the way to positive 140 degree Fahrenheit. The complete kit meets or exceeds the Department of Transportation regulations. Another neat feature that it comes with is this bracket right here. So the battery case slides onto the bracket. This bracket can mount to your trailer frame, side mount design, and it's going to have this bar right here. It slides through the slot and what that does is it lines up with the hole right here and that's a lockable design. So you can pass through a small padlock there and you can lock the unit. Really nice design to the unit and that is included. All your mounting hardware is going to need to be provided separately. It's not included. But that's going to do it for today's look at the Tekonsha breakaway away kit with the charger.

The material was delivered as promised. It seems to be as stated on the web site. But my truck is in the body shop for repairs, both skin panels for the box had to be replaced. so I am waiting to get the truck back. I also have to buy a cargo trailer and will need to buy more stuff for it. so I have no experience using what I have already purchased. After the truck and trailer are finished I am moving to Washington State. It will be a few more months before I can sell the house. 490207

Do you have a question about this Trailer Breakaway Kit?


  • 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.

  • Breakaway Kit Recommendation for a Triple Axle Trailer with 6 Brakes
  • We do have a breakaway kit available for your triple axle trailer with 6 brakes. For your trailer, I recommend the Tekonsha Breakaway Kit, # 20020. This kit will work with 1, 2, 3 or 4 axle trailers. Like the Hopkins kit, this kit includes a sealed, rechargeable 12 volt battery and it also includes a battery charger.

  • Parts Needed to Add Electric Brakes to a Wells Cargo SW-10 Single-Axle Service Wagon Trailer
  • A good starting point for your project to add electric drum brakes to your trailer is a review of the linked article which covers this process in detail. You will need to select brakes based on the weight rating of the axle on your trailer, which should be indicated on a sticker or plate, and you'll need to select new hub/drum assemblies that use the same bearings as the hubs currently on your trailer. This will ensure compatibility of the new hub/drum assemblies with your spindles. If...

  • Difference Between Pro Series Breakaway Systems # 50-85-315 and # 50-85-320
  • The Pro Series Breakaway System, # 50-85-320, is basically just an updated version of the part # 50-85-315. The only difference between these two systems is that the newer model comes with a battery box with additional mounting tabs. Part # 50-85-315 only had mounting tabs on the back of the box and part # 50-85-320 has mounting tables on the back, bottom and top. Eventually, part # 50-85-320 will completely replace part # 50-85-315.

  • Do Tekonsha Breakaway Kit with Charger, # 20020 and # 2028 Come with the Same Charger
  • Both the Tekonsha Breakaway Kit with Charger, # 20020, and the Tekonsha Breakaway Kit with Charger, Clamp On, # 2028, come with the same charger. The only difference is how each system mounts to the trailer. Break away batteries require a special charger because they are smaller than a regular 12 volt battery. Trying to charge it just through the 12 volt circuit from a trailer connector can overcharge the battery. The charger prevents that from happening after the battery has been charged...

  • Replacing Break-Away System Cable and Pin on Travel Trailer
  • The configuration of the breakaway pin can vary from manufacturer to manufacturer, and between models of breakaway switches. When you pull the old pin to replace it with the new one, the brakes will indeed apply, but they should let loose when you insert the pin back into the switch. Since the cable is the only worn part, you might be best off by just replacing the cable portion itself with a coiled cable like # RM-8603 offered from Roadmaster.

  • Troubleshooting Trailer Break-Away System on Camper
  • It sounds as if your breakaway system is not functioning. On a properly working system, the brakes would engage regardless of whether or not the 7-way was plugged into the vehicle. It is not necessary to have an additional break away battery if the battery on your trailer has sufficient power to keep the brakes applied for 15 minutes once the break away pin is pulled. Because of the importance of the breakaway system, it really should really have its own battery. Since the system...

  • Can Tekonsha Trailer Breakaway Kit be Wired to Trailer Battery?
  • The Tekonsha Trailer Breakaway Kit with Built-in Battery Charger # 20020 cannot be charged through a 12V circuit because that would result in overcharging the battery which is why it has its own battery. That battery is also the power source that was referred to in the video.

  • Solution for Breakaway Pin on Trailer that Won't Come Out
  • If you have a breakaway switch where you can't pull the pin out it's probably a good time to replace the switch. It sounds like the cable might have broken before the pin would come out which is not a good sign. For a new switch you can use the part # 2005-P which due to the universal design of these switches will work with what you have regardless of if it's a Tekonsha setup.

  • Does Tekonsha Breakaway Kit 20020 Require Additional Circuit Breaker
  • Your trailer brakes won't necessarily draw 30 amps when activated so the Tekonsha Breakaway Kit part # 20020 will still work fine even though it uses a lighter gauge wire. 20 amps is the size breaker that is recommended for the circuit to protect it since it's a tandem axle but that does not imply that it draws 20 amps all the time. We have found that this kit works well from what our customers have came back and replied with. No additional breakers will be needed.

  • Breakaway Kit Recommendation For Triple Axle Trailer With Brakes

  • How to Disconnect Breakaway Cable from Tow Vehicle
  • It's going to depend on how the break away cable is connected to the vehicle. If the cable is looped through a safety chain loop on the hitch, you can unplug the cable from the breakaway switch, detach it from the safety chain loop and plug the breakaway pin back in. If a split ring or quick link like part # 750-3204 is used, disconnect the cable from the split ring or quick link. Pulling the breakaway pin to get the cable off won't hurt anything, just plug it right back in so the battery...

  • Troubleshooting Trailer Breakaway Wiring that Melts When Pin is Pulled
  • Do the brakes seem to work fine when used normally? The Tekonsha breakaway kit # 20020 normally can be used on trailers with up to 4 brake axles. The problem has to do with the amount of amperage draw the brakes are trying to put on the system and not the battery though. I'd look for a short on the trailer's wiring or maybe you have a bad trailer magnet. I attached a help article on troubleshooting trailer brake magnets for you to check out as well.

  • Is it Okay to Insert the Breakaway Pin After it Accidentally Became Unplugged
  • You will have no problem at all. The pin on the breakaway switch simply closes or opens the circuit from the breakaway battery to the trailer brakes. In fact, many people like to test their trailer brakes by pulling the breakaway pin. As long as it is fully inserted, you are good to go. If you broke the pin, cable or box, I attached a link to all of our replacement pins and cables and a link to our replacement switches for you to check out. Be sure to choose a pin with the same design...

  • Troubleshooting Camper Breakaway Switch with Pin That Will Not Come Out
  • I am glad you were able to safety return home after your camper's brakes locked up. It sounds like your breakaway switch could be corroded internally. That would explain why the pin would not come out. It is possible that same corrosion caused a short inside the switch that in turn caused the breakaway battery to apply the trailer brakes. We can help you with a complete new breakaway kit like # 50-85-315 or the Tekonsha unit you referenced, part # 20020. We also offer breakaway switches...

  • Replacement Trailer Breakaway Kit Recommendation for Trailer with Trailermate Kit
  • For a replacement breakaway kit the Tekonsha kit part # 20020 would be a great option to replace everything. You didn't mention which parts you'd need to replace though. Commonly people want to replace just the switch which for that you would want the part # 2005-P. Due to the universal nature of how these install it would easily replace the switch you have if that's what you were in need of.

  • Troubleshooting Trailer Breakaway Kit on Trailer with 2016 Ram 2500
  • Typically, a trailer breakaway kit will have enough power to engage the trailer's brakes for fifteen minutes once the pin is removed. So, if the pin was removed while your vehicle was idle, then it's possible that the battery had died before getting back on the road during your trip. This would explain not noticing the brakes locking up while driving, even though the pin was not present. If you need a replacement battery, you can use the Hopkins Breakaway Kit Replacement 12V Battery...

  • Can Trailer Connector On Truck Charge Trailer Breakaway Battery Once It Is Dead
  • The current from the truck will not charge the battery in the Tekonsha Breakaway Kit, part # 20020 if the battery is completely dead. My contact at Tekonsha told me that it will charge the battery at a very low rate if the charger senses any charge on the battery. The charger in the 20020 will maintain a charge for the breakaway battery once it reaches its full charge. My recommendation is to use a battery charger like part # CTEK56865 to charge the battery when it is not being used....

  • Could Road Debris Pull the Pin on Trailer Breakaway System
  • Once the pin on the break away switch is pulled, the brakes on the trailer will engage. I have not heard of this occurring, but it is possible. I would recommend routing the cable that pulls the pin as close as possible to the trailer frame. You can use a few strips of electrical tape to hold the cable in place so that it is not hanging down and easily snagged. If the trailer should come loose and the safety chains should fail, the tape would not prevent the cable from pulling the pin...

  • Breakaway System with Charger for a 20 Foot Car Hauler Trailer
