A Warner trailer brake magnet is a crucial component of your trailer’s braking system. It’s what creates the magnetic force needed to engage the brakes when you activate the brake controller in your tow vehicle. If you’re having trouble with your trailer brakes, the magnet could be the culprit. This comprehensive guide will delve into the common problems associated with Warner trailer brake magnets, how to diagnose them, and provide effective solutions.

Understanding the Warner Trailer Brake Magnet
The Warner trailer brake magnet is an electromagnet that plays a vital role in applying the brakes on your trailer. When you activate the brake controller, it sends an electrical current to the magnet, creating a magnetic field. This magnetic field attracts the armature, which is connected to the brake shoes. The movement of the armature forces the brake shoes against the drum, slowing or stopping the trailer. A malfunctioning magnet can lead to anything from reduced braking performance to complete brake failure, making it critical to understand how it works and how to diagnose problems. If you experience a dead battery car wont start, ensure your tow vehicle’s electrical system is functioning correctly before troubleshooting the trailer brakes.
Common Problems with Warner Trailer Brake Magnets
Several issues can arise with your Warner trailer brake magnet:
- Burned-out Coil: The coil within the magnet can overheat and fail, typically due to excessive current or a short circuit.
- Broken Wires: The wires connecting the magnet to the trailer’s wiring harness can become damaged or corroded, interrupting the flow of electricity.
- Worn Armature: Over time, the armature can wear down, reducing its ability to effectively engage the brakes.
- Corrosion: Exposure to the elements can cause corrosion on the magnet itself, impacting its performance.
- Mechanical Damage: Physical impacts or debris can damage the magnet, leading to malfunctions.
Diagnosing a Faulty Warner Trailer Brake Magnet
Diagnosing a Warner trailer brake magnet problem involves a few key steps:
- Visual Inspection: Check for any visible signs of damage, corrosion, or loose wires.
- Voltage Test: Use a multimeter to test the voltage at the magnet’s terminals. This will help determine if the magnet is receiving the correct power.
- Resistance Test: Measure the resistance of the magnet’s coil using a multimeter. A reading outside the specified range indicates a problem with the coil.
- Physical Check: Inspect the armature for wear and tear and ensure it moves freely.
How to Replace a Warner Trailer Brake Magnet
Replacing a Warner trailer brake magnet is a relatively straightforward process:
- Disconnect the Wiring: Disconnect the wires connected to the old magnet.
- Remove the Old Magnet: Depending on the brake assembly, you may need to remove a few bolts or clips to remove the old magnet.
- Install the New Magnet: Place the new magnet in position and secure it with the appropriate hardware.
- Reconnect the Wiring: Reconnect the wires to the new magnet, ensuring they are securely attached.
- Test the Brakes: After installation, test the trailer brakes to ensure they are functioning correctly. A new battery car keeps dying could be a sign of a faulty charging system which can also impact trailer brakes.
“A common mistake people make is not checking the wiring thoroughly. A simple break in the wiring can cause the entire brake system to malfunction,” says John Smith, Senior Automotive Electrical Technician at Acme Auto Repair. “Always double-check your connections.”
Preventing Warner Trailer Brake Magnet Problems
Regular maintenance can help prevent issues with your Warner trailer brake magnets:
- Regular Inspections: Inspect your trailer brakes regularly for signs of wear or damage.
- Keep Brakes Clean: Clean the brakes regularly to remove dirt, debris, and corrosion. This also includes cleaning the brake magnet.
- Proper Adjustment: Ensure your trailer brakes are properly adjusted to prevent overheating and premature wear. This is especially important if you have a bad cell on car battery as it may affect the braking system’s performance.
- Protect from the Elements: Whenever possible, store your trailer in a covered area to protect the brakes and magnets from the elements.
Conclusion
The Warner trailer brake magnet is a vital component of your trailer’s braking system. Understanding its function, common problems, and diagnostic procedures can save you time, money, and potential headaches down the road. Regular maintenance and prompt repairs are crucial for ensuring the safety and reliability of your trailer brakes. Don’t ignore any signs of trouble with your Warner trailer brake magnet. If you suspect a problem, address it immediately to prevent further damage and ensure safe towing. If you’re experiencing issues such as dead battery cell symptoms or prius bad 12v battery symptoms, it’s important to address them promptly as they might indirectly affect other electrical systems in your vehicle, including the trailer brakes.
“Remember, preventative maintenance is key,” adds John Smith. “A little bit of care can go a long way in preventing costly repairs and ensuring your safety on the road.”
