  • Recommended Trailer Break Away System for 9000 lb Enclosed Car Hauler
  • Since you're dealing with a fairly heavy trailer, I'd recommend going with the Bright Way # 3802311 break away system. The kit includes a 10Ah battery and a 2 amp charger. The battery box features a nice push-to-test feature that allows you to check on the status of your break away system with the push of a button. The 10Ah battery is a must because if you get stopped for a DOT inspection, the system needs to be able to hold the trailer for at least 10 minutes if the switch is pulled. I'll...

  • How Long Will Battery of Bright Way Trailer Breakaway Kit Last
  • The battery that comes with the Bright Way Trailer Breakaway Kit with Switch, 12V, 5-Amp-Hour Battery, and Charger # 3802339 is a 12 volt sealed lead-acid battery and these batteries have a life cycle that can vary quite a bit, but typically it has quite a long life of 3-5 years, which is what you should expect with this kit. The battery, for which the replacement is part # 3801250 will constantly be charged when you install it on the trailer. This kit has a charger and connects to your...

  • Trailer Breakaway Kit For Replacement of Melted Kit
  • I'm certainly sorry to hear that; there are a couple of issues that may have caused this, from a bad kit to the far more likely scenario of there being a short somewhere along the wiring, though it's not possible for me to say with any real certainty. I do have to say that the breakaway definitely needs its own battery, which is required by law in most states. I highly recommend going with a breakaway kit that has its own battery, from Bright Way. You can choose from either a 5 or 10...

  • Break Away System Recommendation for 4 Axle Trailer
  • I don't offer a breakaway system that's compatible with a 4 axle trailer that provides the test lamp function, but we do offer a breakaway system that would be compatible. The Tekonsha # 2028 Shur-Set III will work on trailers with 1-4 axles. The kit includes a battery charger that's tied into the 12-v feed from the trailer connector, so it'll keep the battery topped off at all times as you're towing.

  • What is Difference Between Breakaway Kit for Trailer that's Rated for Tandem Axles and Quad Axles
  • The difference between a trailer breakaway system that can work on a trailer with up to 2 axles and one that can handle up to 4 axles is the battery the kit has and the amount of amp hours it can provide since the more brake assemblies there are the more amps it takes to activate them all. The part # 3802311 is a 10 amp hour setup that could work on 4 axles whereas the kit you referenced # HM20001 has a battery with only a 5 amp hour rating and that's why it's rated for use with tandem...

  • Mounting Hole Pattern of Curt C52042 Push to Test Trailer Break Away System Battery Box
  • I had one of the # C52042 push to test break away kits pulled from inventory, and found that the bolt pattern of the # C52042 measures 5-1/2 by 3-1/2 inches. I've linked though our in-stock systems and haven't found a push to test break away kit with the same 3 x 4-1/2 bolt pattern as the # C52040. However, since the # C52042 is larger, you could simply fasten it to the trailer frame by drilling through the bottom of the battery box, if you're reluctant to drill new mounting holes into...

  • Where Does 3rd Wire On 3-Wire Breakaway Switch Get Connected To?
  • The 3rd wire on a 3-wire breakaway switch like the Hopkins LED Breakaway Switch with 7" Lead Wires # HM20059 gets grounded to the trailer frame or tied in to the main ground on your trailers tongue. The only difference between a 2-wire and 3-wire switch is the 3-wire switch has its own ground wire. I included a wiring diagram of the # HM20059 for you to take a look at.

  • Can New 7-Way Trailer Wiring Rewire be Tested
  • The easiest way to tell if a trailer's 7-way wiring is functional is to have a vehicle with a 7-way nearby so you can just plug it in and test the functions. Otherwise we have a 7-way tester part # 8010 which I realize may not be the most practical solution. Or you could run 12 volt jumper wires from a vehicle's positive battery post to all of the circuits on the 7-way with a jumper wire ran from the ground pin to the negative side of the battery. For just the brakes you can run the...

  • How is Breakaway Switch Activated for Flat Towing a 2015 Jeep Wrangler Unlimited
  • The Hopkins Engager Push-To-Test Trailer Breakaway Kit w/ Built-In Charger # 20099 that you referenced is actually designed to activate electric trailer brakes and is typically installed on the trailer tongue. Since it sounds like you are getting your 2015 Jeep Wrangler Unlimited ready to flat tow you won't be needing this to activate your trailer brakes as a supplemental braking system will connect directly to the battery on your Jeep for power in an emergency situation. For example,...

  • Can Trailer Breakaway Kit Be Installed Into Junction Box for Cleaner Connections

While we don't have a video to show how this is done, you can use the attached diagram that I've put together for you.

For example, the Tekonsha Push-To-Test Trailer Breakaway Kit # 50-85-313 is rated for up to 3 axles while the Hopkins Engager Push-To-Test Trailer Breakaway Kit # 20099 is only rated for up to 2 axles.

  • Could Trailer Breakaway System be Used as Parking Brake
  • Breakaway systems should not be used as a parking brake. Typically they only hold the brakes of the trailer for about 10 minutes at max application. Since you have electric brakes you'd want to look into a wheel chock type setup to keep the trailer from moving when parked like the Buyers Products Wheel Chock Set # 337WC24483. This would be the safest way to prevent the trailer from moving. Check out the review video link I attached for more info as well.

  • Troubleshooting Install of Curt Breakaway Kit on Trailer Where Brake Lock Up
  • Since your trailer doesn't use standard colors for it's wiring for lighting and braking you are going to have to wire in the breakaway kit # C52042 by function instead of by color. I won't be able to tell you which color is which on your trailer as you'll have to determine that by either tracing the wiring or using a jumper wire from a car battery to first determine all of the functions. So the red wire of the # C52042 needs to connect to the 12 volt accessory circuit of your trailer...

  • 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...

  • How To Charge Your Breakaway Switch Battery On Your Trailer
  • The Bright Way Trailer Brakeaway Kit # 3802308 has a built in 1-AMP charger. So when your truck is connected it will be charging. There should be no draw going out while the trailer is disconnected so it should be ready to rip whenever you're ready to haul. I recommend wiring it up using a junction box # 3375601101. I've included two videos for you to watch to see how I set up our enclosed trailer at our shop.

  • 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...

  • Can I Install the Bright Way Breakaway Kit with a Charge Line for the Breakaway Battery
  • The Bright Way Trailer Breakaway Kit # 3802354 can be installed in a manner that either does or does not take a charge from the tow vehicle while it is running; the best way to complete an installation where it does take a maintenance charge from your tow vehicle's 7 way connection is using the Bright Way Trailer Breakaway Charger # 3802349. Installing this charger in the manner shown in the review and installation video linked to this answer is going to be the best way to make sure that...

  • Will the Hopkins Engager Trailer Breakaway Kit Keep Charging the Battery with the Truck Turned Off
  • First it is important to know that the battery on the Engager break away kit # 20099 will only be charging as long as the 12 volt circuit is providing power. If you shut off the vehicle and disconnect the trailer it will not be charging. When there is power it will continue to provide a maintenance charger to the battery to keep it at or near full power. You would want to disconnect the trailer from the vehicle if you do not want it to draw power from the vehicle battery when the truck...

I'd be willing to bet the hinge on the left side of the door isn't fully seated which is causing the issue. Check to see if you can pop the hinge back onto the posts of the section of the hinge that is attached to the housing. I also attached an install video for this for you to check out as well.

  • Electric Trailer Brakes Engaging
  • Thanks for the nice words and all that information! It certainly isn't normal that your trailer brakes are engaging without a brake controller though there are a couple of reasons why this can happen. My guess is a wiring issue on the trailer where the wires are making contact and 12 volt power is getting through to the brakes. So I recommend going over the wiring from your brakes and tracing it to see if there is an issue there. If need be you can replace with 10 gauge wire # 10-1-1. Or...

  • How to Wire a Breakaway Switch to the Trailer Battery
  • In order to install a two wire breakaway switch like the Replacement Breakaway Switch with Cable and Pin part # 54-85-007 to an existing trailer battery you will want to attach one of the wires to the brake output signal (usually blue) on the trailer and the other wire to the trailer battery. The wires are non-polarized so it doesn't matter which wire is attached to battery/brake output signal. However, most states require that the breakaway switch be wired to a separate independent...

  • Breakaway Kit Not Working Properly and Causing Issues with my Brake Controller

Then if you pull the pin on the breakaway switch the trailer brakes do not work and will not work again even using the truck until you put the pin back in the breakaway switch. If this is the case there is a wiring problem with your breakaway kit the main trailer brake wire should run directly to the brakes and the breakaway kit should only be spliced into that. It sounds as though the trailer...

  • 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...

  • Could Trailer Breakaway Battery Setup be Used to Power Interior Lights
  • Breakaway batteries aren't typically used for powering interior lights but with a kit like the Hopkins Engager part # 20099 you'd have a kit that would come with a battery charger as well. I'd recommend LED interior lights as they draw considerably less than incandescents like the Optronics kit part # RVILL34.

  • Why Would Trailer Interior Lights Not Work with Breakaway System Installed
  • Sounds like you have the 12 volt power circuit of your trailer either running to only your breakaway battery or only the trailer lights. Most likely the issue is the connection that you are making from the battery to the 12 volt system. Make sure that the connection is solid and allows both circuits to be active.

  • If the yellow charge light is staying on your Hopkins Engater Push-To-Test Breakaway Kit # 20099 even with the trailer disconnected then I suspect an issue with the circuit board (which is attached to the lid). The battery box is weather resistant but it's not completely waterproof, meaning it's certainly possible that enough moisture crept in to cause some issues and possibly a short in the board. This lid/circuit board is replaceable with part # 20106. The other possibility is...

  • 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...

  • How Much Force does it Take to Pull the Pin on a Break-Away Kit Switch
  • It is a simple switch, so brand compatibility should be a non-issue. When the pin is pulled, two pins are allowed to contact and complete the circuit to engage the brakes. Any switch should work fine. I pulled the Hopkins Switch, part # HM20010, to test it out. It does take a good tug to pull it out and close the switch. You should not need to use two hands, but it should not easily slide out. You do not want the pin coming out when you hit a hard bump. I would not repeatedly pull...

  • Troubleshooting Electric-Over-hydraulic Brakes On Trailer
  • There might be an easy way to solve this issue. Is the display on your brake controller red? If so, then it is probably the older Prodigy model and will not work for the electric-over-hydraulic system you have on your new trailer. That would explain why it works on your horse trailer with electric brakes. It still receives the current from the brake controller, but the controller is not designed to work with electric-over-hydraulic systems. If you have a blue display, then you probably...

  • Could Trailer Breakaway Battery Power RV Powered Jack
  • If the jack drew less than 10 amps the Bright Way Push-to-Test Trailer Breakaway Kit with 2-Amp Charger and 10 Ah Battery # 3802311 would work decently but typically they draw more than that. A better option would be a deep cycle battery like the part # BRW34FR which is rated for 75 amps. Then for a battery box the # 329-HM300BKS would work great.

  • Replacement Breakaway Cable for Trailer with Dexter Brakes
  • I do have options for you but just because the trailer has Dexter brakes does not mean it will also have a Dexter breakaway kit. If you want to replace just cable and pin then I will need to know the brand and model of your breakaway kit which can be found on the top of the switch. That said, breakaway kits are universal so it would be easiest to just replace both the switch and cable/pin with the Replacement Breakaway Switch with Cable and Pin part # K71-691. There are only two wires that...

  • Is a Dead Battery Causing Fuses to Blow When I Plug In My Trailer
  • There could be a couple causes of this. It could be the battery, since a dead battery can mimic an overload and cause fuses to blow but there also could be an issue with the wiring as you've noticed with the issues on the running and brake lights. I would start by taking the battery to get tested and replaced if needed, but I also recommend going through all of the wiring and making repairs where needed. I will also say that a trailer battery typically goes bad after this length of...

  • Why Do Trailer Breakaway Kits Have Their Own Battery
  • It's always a good idea to use a dedicated power supply for the breakaway switch since you would be covered if the main trailer battery were to go dead. There are also some states that require the power source for the breakaway switch to be separate from the main trailer battery. The Hopkins Engager Push-To-Test Trailer Breakaway Kit part # 20099 will be an excellent option for this system.

  • Using Trailer Mounted Battery to Power Both Winch and Break-Away System
  • You can use a large marine battery to power your winch as well as the breakaway system, people do it all the time. However, it's not the best practice. You can connect the marine battery to the 12-volt accessory feed from the 7-way, but the circuit doesn't have enough capacity to charge a dead or nearly depleted battery. So, lets say you run down your battery from using the winch, didn't get around to recharging it using shore power, and your battery is nearly dead. Per DOT regulations,...

  • 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.

  • Power Draw On Tow Vehicle Battery to Charge Hopkins Engager Push-To-Test Trailer Breakaway Battery
  • The Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger part # 20400 has a maximum power amp draw of 2 amps to charge the breakaway battery. The power draw is so low is will not drain the tow vehicle's battery. It will also only charge when the trailer is connected to the tow vehicle and the 12V circuit is active. On some vehicle's that does require the ignition to be turned on.

  • Troubleshooting Trailer Breakaway Wire That Didnt Activate Trailer Brakes
  • It sounds like you had not just a breakaway pin pulled but a wiring issue. If not, the breakaway wasn't connected to your trailer correctly as the brakes should be activated but the trailer tail lights wouldn't be. To me it sounds like the pin is connected to the brake lights and not the brake magnets. I've attached an article to help with the connections and have also attached a couple videos and a diagram. It sounds like you may need the Hopkins Replacement Break-Away Switch, 7"...

  • Charging a Trailer Breakaway System Battery Using the 12 Volt Circuit on a 7-Way Connector
  • To charge the battery in the Engager Trailer BreakAway Kit, # 20099, you can attach the wire from the 12 volt circuit on the trailer side 7-Way (1 oclock position on the back of the trailer side 7-Way where the wires attach) to the input wire on the trailer breakaway system. This system has a charger built in to it. As long as it is connected to a function 12 volt circuit it will charge the battery. When connected to the towing vehicle and the vehicle on and/or running, the 12 volt circuit...

  • 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...

  • Will Having Breakaway Battery and Dump Trailer Battery Connected Cause Problems
  • When two batteries are connected together they will attempt to balance the same voltage so if one battery was less charged than the other it would draw amperage from the other one till they both balanced out. It really won't hurt anything, but if you drain the dump battery from using the dump feature you will eventually drain the weaker breakaway battery too as it struggles to charge the larger battery. It would be probably your best option to have the two on separate charge wires.

  • Testing Trailer Brake Magnets With Full 12V Power Supplied Using the Brake Controller Override
  • In order to deliver full 12 volt power to your brakes while performing a pull test you can also use the override functions on your brake controller. This will avoid installing any switches, or disturbing any of the existing functional wiring. Switches can be forgotten, and additional connection points or unnecessary splices of the breakaway system can lead to problems like corrosion down the road. To use the override function on your brake controller you would turn the power of the...

  • Troubleshooting Hopkins Trailer Breakaway System Not Charging Battery
  • First you will want to check the wiring of the Hopking Breakaway # 20099. If the black wire from the breakaway box is not receiving 12 volts from the 7-way on your tow vehicle it will charge the battery. You will want to use a circuit tester like part # PTW2993 to test this wire for 12 volts when the vehicle is connected and running. If there is no voltage there then you will need to trace this wire back to where it connects to your vehicle wiring and make sure it is connected securely...

  • How Does Breakaway Switch Normally Wire to Trailer Wiring

I attached a diagram that shows how it all gets connected.

  • Where Should the Ground Wire be Attached for a Trailer Breakaway Battery
  • You will likely have several different grounds on any given trailer. The breakaway battery can ground by itself to the frame and to the trailer connector's ground if you want. But at the very least ground the battery to the frame. The brake magnets should be grounded independently near the magnets (axle or frame) for the best results. As long as the breakaway battery is grounded to the trailer frame and the magnets are properly grounded it will work should the trailer separate from...

  • Will The Breakaway Switch Draw Power When Disconnected From Tow Vehicle
  • When you unhook the trailer from the SUV you are not going to pull the pin of the breakaway switch to activate the trailer brakes. The only time the breakaway switch is going to pull power is if the pin is pulled from the breakaway switch which activates the brakes. The other side of your breakaway switch has a cable that attaches to the vehicle's frame or hitch while towing. Most people use a clip to attach the loop at the end of the cable to the vehicle's frame or loop it through the...

  • 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...

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...
