I have not installed this yet but have looked over everything I received with this kit. I couldn't be happier with the it. There are only a few pieces needed that aren't included and they are choice of electrical connectors and a seat tapping screw to attach the switch itself. Everything else is in the box. The instructions are clear and easy to understand. I will be attaching this to the trailer Jack on a 1962 Airstream Ambassador.

Ordered this on Tuesday - arrived on Thursday... awesome delivery time! Bought this to put on my 1996 Coleman/Fleetwood Shenandoah popup camper since for some reason ours didn't come with a breakaway kit. Wanted to mount the battery and charger box on the tongue of the trailer, but the supplied U-bolts that came with the kit will NOT go all the way around the rectangular frame rails of the trailer tongue. Ended up going to the local big-box hardware store and buying some threaded rod and made my own mounting brackets. Instructions included are very easy to follow. Only thing I saw that was missing in the kit that you'll need for installation was a package of tap-splice connectors for connecting the breakaway switch and the battery and charger to the existing trailer wiring.

Order was complete and delivered in a timely manner. Only problem (minor) was the 7way pigtail was not wired to color code. Had to use test light to get 3 of the wires in correct location. Could be a problem if someone wasn't comfortable with ringing out wires.

I ordered electric brakes and breakaway kit I place my order on Wednesday afternoon and could have taken advantage of free shipping but to the option for 2 day delivery.because we are at the very end of reconditioning our flatbed trailer and I want it out of the shop the parts ordered arrived the next day matched up perfectly and the trailer is out of my shop and the next project is in. I buy all my trailer replacement parts at etrailer due to their prompt and courteous service

The products were acceptable quality and the customer service was UNEQUALED, EXEMPLARY, GREAT, etc. The trailer overhaul job went well and we hauled a capacity load almost 1500 miles in some difficult road conditions, stopping only for fuel and to sleep. We'll use your products again.

Great products with fast free shipping (large enough order. I just installed the tow package on my suburban and it was easy when following the videos. It was nice to have everything already gathered and ready to go. Not having to go but ring terminals, wires, zip ties, screws and testers made a daunting project simple.



- HM20001
by:

Easy enough to install. Put it on a home built trailer. Can't say that I've had to use it but it seems to be built well enough. I did check it after install and it applied the brakes but I was in the drive way and not going down the highway at 50+ MPH. And hope I don't ever have to use it in those circumstances.

Ask the Experts about this Hopkins Trailer Breakaway Kit



  • Can a Breakaway System and Brake Controller be Installed at Same Time on 2002 Dodge Grand Caravan
    You can have both a brake controller and a breakaway system since they serve 2 different functions. A brake controller, which may be required by law in your area (check local and state laws) will apply the trailer brakes when you apply the tow vehicle brakes. A breakaway system only applies the brakes should the trailer become uncoupled from the tow vehicle. In many states a breakaway system is also required by law. The breakaway system needs to be able to apply the trailer brakes on full...

  • How to Reset the Hopkins Trailer Break-Away Kit with Charger # HM20001
    You are correct. The system does not have to be reset electrically to allow for normal trailer operation. Instead, like you said, the pin, or what separates the contacts, needs to be put back into place. What happens is, if the trailer detaches from the tow vehicle, the mechanism separating the pins is pulled out. This allows the contacts to touch which in turn engages the break away system to stop the trailer.

  • Can The Battery In The Hopkins Trailer Break-Away Kit with Charger # HM20001 Be Mounted On Its Side
    I spoke with my contact at Hopkins and he said on the Hopkins Trailer Break-Away Kit with Charger, part # HM20001, it is a gel cell battery so it can be mounted on its side. I am including a link to a FAQ page on trailer breakaway systems and a video link to a installation of a breakaway kit.

  • Should the Cable on Hopkins Break-Away Kit # HM20001 Engage Trailer Brakes If Safety Chains Break
    The breakaway cable on the Hopkins Break-Away Kit, part # HM20001, should engage the trailer brakes if the trailer becomes disconnected from the tow vehicle and the safety chains fail. So you will want the breakaway kit to be the last line of defense against a runaway trailer. As far as length of the breakaway cable, that will be determined by where the breakaway kit will be installed on the trailer. I am including a link to a FAQ page on breakaway kit installation and a link to a video...

  • Troubleshooting Lighting on Snowmobile Trailer that Doesn't Work
    You have the issue isolated to being on the trailer somewhere. What you will need to do is first check that the trailer connector is clean and free of any corrosion as that's the easiest thing to check. Next you will want to check the conditions of the ground wire from that connector to the frame of the trailer. Since all of the lights aren't working it makes me think the main ground that feeds all the lights isn't sufficient. Aside from that it could be a wiring issue to the assemblies...

  • Troubleshooting Trailer Brakes That Stop Working When It Rains
    I'll start this off by saying that I don't think the issue has anything to do with the breakaway switch or junction box, It sounds to me like the rain is causing a short on your wiring and this is what is causing your brakes to go out; since you just had new leaf springs put on the 5th wheel trailer it's possible that something was damaged during the repair process. I would first examine the ground wire connection on your trailer-just because that's an extremely common cause of shorts...

  • Troubleshooting 7-Way Replacing 6-Way Install Where Brake Output Stopped Working
    The is most likely related to the fact that there are two ways a 6-way will typically get wired and the only difference is that the 12 volt accessory circuit and the brake output circuit are switched. I attached a picture that shows a diagram for a 6-way for you to check out. Most likely something got mixed up when making the conversion due to the difference there so you'd need to check the wiring.

  • 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 the...

  • 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.

  • Will a Breakaway Kit Damage the Brake Controller if Tested with the Trailer Connected
    I would disconnect the connector before testing so that you do not back feed power to the Prodigy controller. This is the best way to ensure there is no damage to the controller and to be sure the breakaway system is functioning properly. The breakaway is designed to work when the trailer has detached from the vehicle so the electrical connection would be severed. Most Brake controllers are protected from back feed so if you did test the breakaway with the trailer connected you should...

  • What is the Function for the 3 Wires Coming out of the Charger
    The 3 wire component is the charger and receives 12V power from the vehicle connector and charges the breakaway battery. Now the blue wire coming off the charger will go out to the breakaway switch. I included a video on a similar charger # 20011 for you to look at. It will have the same functions as your charger.

  • Does Bright Way Trailer Breakaway Kit Come With Mounting Hardware
    The Bright Way Trailer Breakaway Kit with Switch, 12V, 5-Amp-Hour Battery, and Charger # 3802339 does not come with mounting hardware; you would need to supply your own self-tapping screws from a local hardware store. If you were looking for a breakaway kit that did come with mounting hardware, I recommend the Hopkins Trailer Breakaway Kit with Built-In Battery Charger - Side Load # HM20001. This comes with self-tapping screws as well as U-bolts so you could mount it to your jack post...

  • 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.

  • Does Trailer Breakaway Battery have to be Charged for Truck to Sense Trailer Connection
    The breakaway system battery is not related to whether or not your truck will sense a trailer connection. It actually will look for the slight amperage draw that brake magnets create to determine this. While I strongly recommend waiting to have your breakaway battery fully charged before towing your vehicle will see a connection whether it is or not.

  • 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...

  • Can Trailer Brakes Lock Up if a Breakaway System has a Dead Battery
    No, if the breakaway battery on the trailer is dead and the pin is pulled out of the switch then no power would be sent to the trailer brakes and they would not lock up. If they do lock up then the brakes must be getting power from another source or the battery isn't dead. I recommend checking the wiring for shorts and corrosion and fix any pinched or damaged wires as needed. If you suspect the breakaway system is bad I recommend replacing it. One of the most popular systems we carry is...

  • After Installing New Breakaway Kit on Trailer the Brakes Lock Up when Connected to Different Truck
    It sound like you are describing the Engager breakaway system, # 20099, or something similar. The lights indicate the charge level of the breakaway battery. The issue when you plugged in the trailer to the friend's truck could mean that the connector on his truck is not wired the same as it is on your truck and trailer. I imagine that if the brakes were locked up when the trailer was connected to your truck you would have heard the tires scraping the ground or someone would have flagged...

  • Replacement Battery for Hopkins Breakaway Kit 20400
    We do offer a replacement battery for the Hopkins Engager Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger part # 20400, it's the Breakaway Kit Replacement 12 V Battery part # HM20008. Please note, you'll need to test the battery when detached from the trailer. You can also use a volt meter to test the battery directly. I am not sure of the exact issue you're describing but I have attached a few help articles below that go over testing the trailer brake controller.

  • Maintenance Charge for a Trailer Mounted Battery through a 7-Way Trailer Connector and a GMC Acadia
    To supply a maintenance charge to an auxiliary battery you would connect the 12 volt circuit from a 7-Way trailer connector to the positive terminal of the battery. If the battery is mount on the trailer you would ground it to the trailer frame and it also would not hurt to ground it to the main trailer connector ground. This method will provide a maintenance charge like you have said but it will not charge up a battery. For a battery charger I recommend the CTEK 7002 charger # CTEK56353.

  • Trailer Brake Magnets not Not Working on Snowmobile Trailer Towed by a Chevy 2500 HD Silverado
    I think you are going in the right direction. I would start with the ground connections since that is the easiest fix for this type of situation. If the grounds are not making good connections, you are going to have issues. Applying power directly from a 12 volt battery is very different than applying power from a brake controller mounted on the truck and going through two trailer connectors. Make sure the brake magnet wires are attached to a clean, rust and corrosion free part of the trailer...

  • How To Move A Trailer With A Dead Breakaway Battery
    On most breakaway kits such as the Hopkins Brake Master part # HM20001, you will not need to cut or splice any of the wires to move the trailer with a dead battery. If your power supply is not active, then the only effect is that the breakaway system will not send power to your trailer's brakes in a breakaway situation thus allowing for free movement of the trailer. Even if the battery is dead, the brake controller will still allow you to activate your trailer's brakes To prevent further...
