If you’re towing a trailer, you’ll need a working brake system. One important part of the brake system is the trailer breakaway switch. This switch helps to keep your trailer from being towed away if the tow vehicle’s brakes fail. Here’s how to test a trailer breakaway switch.
What Is a Trailer Breakaway Switch?
A trailer breakaway switch is a safety device that is required on all trailers with electric brakes. The switch is designed to engage the brakes on the trailer if it becomes separated from the tow vehicle. For example, this can happen if the trailer hitch breaks or the coupler comes loose. The breakaway switch is usually mounted on the frame of the trailer, and it is connected to the brake controller with a coiled cable.
When the trailer separates from the tow vehicle, the cable is pulled, which activates the switch and applies the brakes on the trailer. This helps to prevent accidents by ensuring that the trailer does not continue to roll away after it has become detached from the tow vehicle.
There are two types of breakaway switches: mechanical and electrical. Mechanical breakaway switches are activated by a spring-loaded plunger, while an electrical current activates electrical breakaway switches. Most breakaway switches are designed to be activated by either type of force, but some are designed for use with specific types of trailers.
For example, some boat trailers have breakaway switches that are only designed to be activated by an electrical current. This prevents false alarms caused by rough terrain or bumpy roads. Therefore, choosing a breakaway switch compatible with your trailer and your tow vehicle is important.
Breakaway switches are an important safety feature and are required by law in many states. If you are unsure whether or not your trailer needs a breakaway switch, consult your owner’s manual or contact a qualified mechanic.
Why Should You Test a Trailer Breakaway Switch?
A trailer breakaway switch is an important safety device that is required by law in many states. The switch is designed to activate the trailer brakes if the trailer becomes detached from the tow vehicle. This can help to prevent a serious accident by keeping the trailer from continuing to roll down the road after it has become detached.
While breakaway switches are not required in all states, they are strongly recommended for any trailer that is being towed on a public highway. Testing the breakaway switch regularly is the best way to ensure that it will function properly if it is ever needed.
9 Tips to Follow on How to Test a Trailer Breakaway Switch
1. Know the Basics
A trailer breakaway switch is designed to engage the brakes on a trailer should it become detached from the towing vehicle. There are two types of breakaway switches: electric and manual. Electric breakaway switches are activated when a certain amount of force is applied to the switch, while manual breakaway switches must be manually triggered in the event of a separation.
You should also familiarize yourself with the specific instructions for testing your breakaway switch, as they may vary slightly depending on the make and model.
2. Check the Battery
If you have an electric breakaway switch, the first thing you’ll need to do is check the battery. This is typically a 9-volt battery and should be located near the switch itself. If the battery is dead, the switch won’t work, so make sure to replace it if necessary.
Though manual breakaway switches do not require a battery, it is still important to check for any corrosion or damage to the switch itself.
3. Test the Switch
Once you’ve confirmed that the battery is working, it’s time to test the switch itself. This can be done by pulling on the switch lever or by pressing the test button if your switch has one. When the switch is activated, you should hear a click and see a light come on. If neither of these things happens, the switch is likely defective and will need to be replaced.
But if the switch does engage, it’s important to test the actual brakes on the trailer to ensure they are working properly. It is recommended to do this in a controlled environment, such as an empty parking lot, and with someone helping you.
4. Check the Wiring
If the switch itself seems to be working, the next step is to check the wiring. Make sure that all of the wires are securely connected and that there are no frayed or exposed sections. If everything looks good, move on to the next step.
You may also want to consider investing in a trailer breakaway switch tester, which can help you quickly and easily test the wiring and connections.
5. Test the Brakes
Now, it’s time to test the brakes themselves. With someone else in the tow vehicle, have them slowly drive forward while you watch the trailer. The brakes should engage as soon as the trailer becomes detached from the vehicle. If they don’t, there may be an issue with the wiring or with the brakes themselves.
The brakes should also be released as soon as the switch is deactivated. If they don’t, it could mean that there is a problem with the brake controller. You may need to have a professional mechanic take a look at it.
6. Check for Leaks
After testing the brakes, it’s a good idea to check for leaks. This is especially important if you have an electric breakaway switch, as a leak in the system can cause the switch to activate prematurely. Simply apply pressure to the brake lever or pedal to check for leaks and look for any signs of fluid coming out.
You may also want to consider investing in a trailer brake pressure tester, which can help you quickly and easily check for any leaks or malfunctions in the system.
7. Replace the Switch
If your breakaway switch isn’t working properly, it’s important to replace it as soon as possible. A defective switch could prevent your brakes from engaging in the event of a separation, which could lead to serious accidents. You can purchase replacement breakaway switches at most automotive stores or online retailers. Just make sure to choose a switch that is compatible with your trailer and tow vehicle.
It’s also a good idea to keep a spare breakaway switch on hand, just in case your current one fails or is damaged. You never know when you might need it.
8. Test Regularly
It’s important to test your breakaway switch regularly, not just once in a while. This will help ensure that it is always in working condition and ready to activate if needed. It’s recommended to test the switch at least once every few months or more frequently if you use your trailer frequently.
The best way to remember to test your breakaway switch is to set a reminder on your calendar or phone. This will help make it a regular part of your trailer maintenance routine.
9. Consult a Professional
If you are unsure how to test your breakaway switch or if you suspect that there may be an issue with it, it’s always best to consult a professional mechanic. They will have the knowledge and experience to properly diagnose any issues and provide recommendations for repair or replacement. Your safety, as well as the safety of others on the road, should be a top priority when it comes to towing a trailer.
Regularly testing your breakaway switch is one simple way to ensure that you are taking all necessary precautions and following best practices for safe towing. So, always test your breakaway switch before hitting the road with your trailer. Better safe than sorry!
That’s it! You’ve now learned how to test a trailer breakaway switch. By following these steps, you can ensure that your trailer’s brakes will engage in the event of a separation.
