heavy duty box , extra material in the mounting are ( other box from a different supplier I had this was weak point & broke mounting ears off not purchased off this site ) - comes fully charge - this should last a long time . This is an important safety item , should not be over looked . I lost my trailer with no break away it jammed underneath my truck - it was ugly !!

- C52044

Product looks well made and installed with just one hitch. If you follow instructions and try to connect the 2 wires, one from the breakaway switch and one from the push to test panel using the supplied connector to the positive post of the battery, you can't close the lid of the battery box properly . It hits the electronics on the inside of the lid. You need to do your own splice ( 2 wires into 1 onto the + post . Not a big deal, but certainly a slight screw up by the manufacture.

  • What 3-Axle Breakaway Kit Comes with a Test Feature and a Charger?
    Yes! The only model we carry that is compatible with a 3-axle trailer and has a test light/charger on the battery case is the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger - Top Load # C52044. I went ahead and attached a demo video that walks you through the features. It is important to note that you need to have a brake controller that works specifically with electric over hydraulic brakes in order for this breakaway to be compatible with your setup.

  • Does a Trailer Need a Battery for the Brakes to Work
    No, you do not need to have an auxiliary battery on the trailer in order for the brakes to work. The brakes are powered by a brake controller like part # C51110 which draws power from the tow vehicle's battery, not the trailer's battery. You will however need a battery on the trailer to activate the breakaway which is required by law in most states however, this battery is very small and is included with most kits like the Curt Push-To-Test Trailer Breakaway Kit part # C52044. If you need...

  • Can You Reduce the Battery Size to Save Weight On a Trailer
    If you are looking to reduce the weight of your battery then the best option is to switch to lithium which are up to 30% lighter than lead acid. In regards to the exact size you need, I really don't recommend straying away from the size the trailer came equipped with originally as this is what they have determine suitable for the trailer and normal use. If you wanted to go with a smaller battery you'd need to calculate your specific needs by running some power draw tests. The Power Sonic...

  • Will Trailer Breakaway Battery Charge Auxiliary Battery
    So it sounds like you are trying to use the Curt Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger # C52044 to charge an auxiliary battery on your enclosed trailer to power lights, and it makes sense that this would not work. This kit is only designed for breakaway batteries, and has a small 5-amp hour battery capacity, which is probably dead, as I'm guessing you are not seeing any LED indicators (either red or green) illuminated. For everybody's safety, breakaway kits -...

  • Recommended Charger for Breakaway Kit Battery When Storing for Long Periods of Time
    If your trailer won't be getting used very often, it is wise to use a maintainer charger on your trailer battery and breakaway battery to keep them in good working order. I recommend using a battery charger like the NOCO Genius # 329-GENIUS5 so it will maintain your battery. This will make it so you can simply plug it in when storing it and you can be sure it will work well when you are ready to tow.

  • Troubleshooting 2002 F-250 Towing Horse Trailer with Working Exterior Lights but No Interior Lights
    It sounds like the interior lights on your trailer are powered through the 12 volt circuit on your Ford's 7-way. So, start by testing to make sure that pin is active. On a standard RV style 7-way, this is located at the 1 o'clock position. I've attached a diagram for visual reference. Using a tester like # PK12741 would be the easiest. You could also simply have a case of corrosion on/in the connectors that is preventing the +12V auxiliary power from reaching the trailer. If this is the...

  • Parts Needed To Add Electric Over Hydraulic Disc Brakes To Triple Axle Toy Hauler
    I would be happy to help! The only triple axle disc brake kits currently offered all have 1/2" wheel studs so we will need to piece a kit together for you. I recommend the Kodiak Disc Brake Kit - 13" Hub/Rotor - 8 on 6-1/2 - E-Coat - 7,000 lbs # K2HR79E which will fit the 7000lb Dexter axles you have, and gives you the 9/16" studs you mentioned. Since you have 3 axles you will need 3 of these kits. Next you will need brake lines of which I recommend the HydraStar Hydraulic Brake Line...
