Expert Answers about 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.

  • Comparing Hopkins Engager Breakaway Kits 20400 and 20099
  • Pretty much the only difference between the Engager breakaway systems # 20099 and # 20400 are the designs of the battery boxes. Both function the same and have the same features. Engager # 20400 is meant to be mounted to the side of the trailer frame whereas # 20099 is designed more from the top of a frame. But ultimately you could install them anywhere there is space so I wouldn't say one is better than the other for you trailer.

  • Recommended Trailer Breakaway Battery Braking System with Integrated Charger
  • The Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger - Side Load - 7" Wire # 20099 is the most popular option by far followed by the top loading version # 20400. This is my recommendation for the best option. Many trailer manufacturers utilize this breakaway kit because of its function and ease of use. I've attached a photo to assist with the installation.

  • Trailer Breakaway Kit Recommendation with 9 amp Hour Battery
  • We don't have a 9 amp hour battery to swap into the battery box of the Engager but I do have a great solution for you. The Dexter Breakaway Kit part # 34-285 is a kit that comes with a 9 amp hour batter and a box large enough to fit the battery size.

  • Wiring Instructions for the Curt Soft Trac Charger
  • You are correct that the Red wire from the Charger for Curt Soft Trac I and II Trailer Breakaway Kits # C52025 is connected to the Battery, the White is connected to Ground, the Blue is connected to the Breakaway Switch. The Black wire that you are asking about will be spliced into the 12V Power wire on your trailer. This should be the wire connected to the pin in the 11 O'clock position on your trailer's 7-Way connector (see attached picture). You can test this out by connecting your trailer...

  • Wiring Directions for Hopkins Engager Push-to-Test Trailer Breakaway Kit
  • The wiring directions for the Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20099 referenced in your question are as follows: 1. Splice one blue wire of the Break-Away Switch to the electric brake wire coming from the trailer side connector. 2. Connect other blue wire of Break-Away Switch to the blue wire (labeled Brake) from the Break-Away box (Note: Blue wires are interchangeable on the Break-Away Switch.) 3.

  • Can Breakaway Switch By Itself Be Used If Trailer Already Had Battery
  • If you have a battery already on your trailer that's getting a charge and would be adequate to hold the brakes of your trailer in the event of a breakaway you could wire just a switch from it to your brake output circuit and you'd be fine. For that you'd only need a switch like the # FA80-00-2040 for a kit with a coiled cable or part # 2005-P for a kit with a straight cable. The battery setups like the part # 20099 would only be needed if you also needed a battery to power the system.

  • Easy Solution for Lost Pin for Trailer Breakaway System
  • The TAP Engager brakeaway kit you have on your trailer is a standard style of breakaway very similar to the Hopkins Engager part # 20099. For a replacement pin setup that would work well we have the # HM20010 which gives you a new switch, pin and cable. This is the easiest way to replace a breakaway pin is replacing the switch and pin all together as the switches themselves are all universal but matching the pins can be a bit harder. For just the pin of this system we have the # HM20051...

  • What is the Difference in Hopkins Engager Breakaway Systems 20099 and 20400
  • Hopkins Engager breakaway systems # 20099 and # 20400 function the same way and have the same features. The main difference is in how they mount. Engager # 20099 is meant to be mounted on top of the frame with the LED indicator and test button facing up. Engager # 20400 was meant to be mounted to the side of the trailer frame so that its LED indicator and test button are also facing up. You will want to make sure the battery in the system you use is protected. That is why breakaway systems...

  • Correct Wiring Installation for aTrailer Breakaway Kit
  • If you are installing a trailer breakaway kit like # C52041, then you can use the 12-volt auxiliary power wire to help provide a maintenance charge on your breakaway kit's battery. A breakaway kit that does not have an onboard charger will have to use 3 wires to operate. One red or black wire (12-volt power) that will come off the 12 volt auxiliary circuit. This wire will keep a maintenance charge on the battery when connected to your vehicle. A white wire that will be the ground and...

  • Pulling Breakaway Switch Pin Causes Battery Box to Burn and Melt and Running Lights Stay On
  • If things start to melt when you pull the breakaway pin from the switch then that indicates a bad short that we have to track down. It also sounds like somehow the trailer running light circuit is being tied into the brake and breakaway system wiring which it should not be; or that there was additional damage in the trailer side connector causing a short between the running light circuit and another circuit. A breakaway system has to be wired up a certain way. I have included a diagram...

  • What is the Expected Life of a Trailer Breakaway Battery During Winter Months
  • Typically, if your trailer is exposed to the elements, the breakaway battery should last at least a full season. There are many variables that can affect a batteries life expectancy. The Engager trailer breakaway # 20099 includes a built in battery charger as is stored inside a weather resistant battery box. The LED tester, when depressed, will advise you if the battery is fully charged and/or needs charging. Most instances the battery can be fully charged in 20 minutes. Another thing...

  • Troubleshooting Engager BreakAway Kit # 20099 When Battery Is Overheating
  • I spoke with my contact at Hopkins about the Engager Trailer BreakAway Kit, part # 20099 you are using on your Airstream. They told me that the battery being so hot is an indication that either the battery is bad, or there may be an issue with the circuitry on the breakaway unit. You will want to make sure the installation to your 12 volt power source has been completed as the instructions state. The white wire should be grounded to a clean bare metal surface on your trailer. The black...

  • Difference Between Hopkins Breakaway Battery Kits HM20001 and 20099
  • The big difference between the Hopkins Engager breakaway kits is that the # HM20001 does not have a charge status display on the lid like the part # 20099 does. The # 20099 allows you to press a button and know what the charge of the battery is like.

  • Can Trailer Breakaway Switch be Used as Parking Brake
  • I do not recommend using a breakaway switch like the Hopkins Engager # 20099 that you referenced as a parking brake to hold the trailer in place. When pulling the pin out of the switch full 12V power will be sent to the trailer brakes and it won't release them until the pin is re-inserted or the battery dies. Locking the brakes up like this for longer periods of time may actually cause damage to the assemblies themselves. A better option to keep your trailer in place when it's parked...

  • Breakaway Pin Melted When Reed Into Breakaway Switch
  • It depends on how long the trailer was sitting there before you reinserted the pin. On a system like the Hopkins Engager # 20099 the battery has a 5 amp-hours capacity so if you were within the 5 hour time limit that would explain why the pin melted. If it melted the whole switch then you can replace it with part # HM20010. Otherwise the replacement cable and pin is part # HM20051. If your trailer had been sitting there for a day or so and your pin was melted then I really am not sure...

  • Where to Attach Cable for Curt Push-To-Test Trailer Breakaway Kit
  • The most common method for attaching the cable for a breakaway kit like the Curt Push-To-Test # C52042 that you referenced is feeding it through the safety chain loop on the trailer hitch. The warning message that you mentioned on the instructions manual caught me a little off guard so I called my contact at Curt and he actually said that "mounting hooks" in that statement refer to the hooks on the safety chains themselves. He said that the cable can absolutely be connected to the tow...

  • 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...

  • Do Trailer Breakaway Kits Have Diodes to Prevent Backfeeding
  • The breakaway kits we offer like the # 20099 do have one-way diodes built into the lid of the boxes so that when the trailer isn't connected the breakaway battery doesn't try to power the rest of the trailer. If you are using a car battery setup that would explain why that's happening. When the breakaway pin is pulled the brakes should activate and make just as much sound as if they were being activated with a brake controller.

  • Comparing Trailer Breakaway Switch Kits
  • Some different brand names of trailer breakaway kits do originate from a common source, and this is also true for items like jacks, landing gear and steps. There really is not a lot to distinguish one from another, since their component parts are virtually identical: a battery, a box, a charger and a switch. The one part that can make a difference is the battery itself. A higher output battery can power brakes on more axles. Hopkins Engager Trailer BreakAway Kit # 20400 can handle 1 or...

  • Can Breakaway Kit Battery Be Charged from Main Trailer Battery Without Depleting It
  • It is permissible to have your trailer breakaway and water pump wired in the way you describe - under certain circumstances. As long as your water pump battery is substantially larger in current capacity than the breakaway battery, and as long as BOTH batteries are in good condition and fully charged before you head out, then the 12V maintenance charge from your vehicle 7-way wiring harness should be able to maintain both batteries without either becoming depleted. I suggest you apply...

  • The Charge Light for Engager Trailer BreakAway Kit Stays On All the Time
  • The fact that it is staying on even when the trailer is not connected is strange. According to the installation details linked for reference, if the trailer is connected to the tow vehicle, the yellow charging light will always be on. The light stays on just to show that the unit is connected and has power. Since it is staying on, it has to be drawing power from the break away battery. The box is water resistant but not water proof. Moisture or corrosion build up in the box or wiring...

  • How Long Does It Take To Charge a Breakaway Battery
  • I assume you are referring to a breakaway battery but this was not specified so please just clarify this for me if that is not the case. That said, I don't really have any accurate charge times for your breakaway battery as there are just too many variable involved. I would say anywhere from 20 minutes to an hour. If you use a meter to measure the voltage on the battery that should then let you know its state of charge. The best option for you if you need to make sure the breakaway...

  • Troubleshooting EOH Actuator That Will Not Release Brakes
  • If your EOH brakes will not disengage the problem could either be mechanical, as in a malfunction with the master cylinder, a clog in the hydraulic lines or broken parts in the brake assemblies themselves. Or it could be electrical in origin, meaning that electrical power is reaching the actuator when it should not. Troubleshooting this type of problem is easiest if you disconnect the trailer and test the tow vehicle and trailer separately. If the brakes release when you unplug the...

  • If Breakaway Switch on Trailer is Left Unplugged with Battery Drain
  • If the battery you disconnected from your trailer is also the battery that powers the breakaway system then having the pin pulled on the switch won't be an issue. If you left the breakaway battery installed on the trailer then the pin being pulled will drain the battery. If the battery stays totally dead for a few months it would need to be replaced most likely. We have three replacement breakaway batteries. We have the Curt part # C52023, the Hopkins part # HM20008, and the Tekonsha...

  • 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 Trailer Be Towed if Battery in Breakaway Kit is Dead
  • Your trailer's brakes will not lock up from the battery in a breakaway kit, like the Hopkins Brake Master # HM20001 being dead. If the breakaway battery is dead there won't be any power supplied from the system and it wouldn't have any impact on your brakes. Your breakaway battery should be tested before towing. If it's dead then it will not be able to do it's job of engaging your trailer's brakes in the event your trailer is separated from your tow vehicle.
