Amid the Covid 19 craziness, I contacted eTrailers to check on an order I had placed and discovered it was back ordered until July. Theresa assisted me in cancelling that order and finding the parts I needed for my trailer in short order. I received the parts promptly and cannot give enough praise to Theresa, she’s an asset to the eTrailer family. 784999

Arrived quicker than expected. Seems to be high quality. Have not had time to install, so I cannot address the difficulty of installation or the performance. 580658

Very good product. Don’t want to see a trailer with thin enough steel that the mounting screws would actually work. Did have a bit of a hard time mounting since the bolt spacing was pretty wide, but got it to work. Kit is complete, works very well, and was relatively simple to install. Recommend it for the money. 642026

Not well. I dont know if I wired it wrong or what, but the battery died. Everything checks out ok with a multimeter except the dead battery.
Larry - 03/18/201950692
If the vehicle 7-way that you are using this with does not have a powered 12-volt connection to help maintain the battery then that may be the issue. If not then check out the installation instructions and refer to page 2 for additional info.

Replaced a outside rail unit on my Trailex enclosed (1999) with this unit, but moved it inside by winch mount to better protect from elements. 1 year in, start of new towing season, still working as designed (brake engage), charging off of tow vehicle 12v power from 7-pin cable source. Would buy again to replace a dead battery, to all new accessories, not a place to scrimp. 258608

Curt makes good stuff, their people are helpful. Unfortunately this kits instructions do not match the wire colors. I informed Curt of this.It shows hooking up black wire from battery/test panel (neg) to ground. The wires from the battery/test panel box are red,white and blue, NO black.I understand how to wire this in any case. 874904

Ask the Experts about this Curt Trailer Breakaway Kit
- Can Trailer Breakaway Kit Be Installed Into Junction Box for Cleaner ConnectionsSure, if you want to install the breakaway kit through the junction box, you would just need to make the connections that would normally run to the wiring harness, into the respective terminals inside the junction box. 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 a junction box, I recommend part # 38656 and for a breakaway kit, I recommend the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger...

- 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...

view full answer... - 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...
view full answer... - Could One Trailer Breakaway Kit be Used on Several Fifth Wheel TrailersBreakaway kits aren't really designed to move from trailer to trailer easily. They are designed for a permanent install. Since nearly all areas will require a breakaway kit to be installed on the trailer the best solution would be to install a breakaway kit like the part # C52042 on all of the trailers. It'll also save you a lot of time trying to swap the kits each time you have to tow a different vehicle.
view full answer... - Comparing Trailer Breakaway Switch KitsSome 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...
view full answer... - Is There a Curt Soft Trac Breakaway Kit that Has Battery Charge IndicatorIf you are looking for a similar trailer breakaway kit that has a built in charger and tester we have the Curt part # C52042 which will show you when it's charging and charged but the part # C52040 that you referenced does not have this feature.
view full answer... - Does Charging Battery of Curt Breakaway Kit # C52042 Take a Long TimeTo charge a battery through the 12 volt accessory circuit of a vehicle and trailer wiring does take some time. If the battery was in a pretty low state of discharge it would not surprise me that it's still charging. If you wanted to charge the battery quickly you'd need a charger that plugs into a wall outlet like the part # CTEK56353.

For a breakaway kit that is rated for use on triple axle trailers you will want to use the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger part # C52042. The Curt breakaway kit as the title suggests also has a built-in push to test feature as well as a side load battery box just like the Hopkins...
view full answer... - How To Move A Trailer With A Dead Breakaway BatteryOn 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...
