Essential Guide to Testing Your RV Breakaway Switch

What is a Breakaway Switch?

The breakaway switch is a safety device designed to automatically engage the trailer brakes and slow down your RV if it disconnects from your tow vehicle. It is powered by the RV's 12-volt battery, not the 7-way cord, making it crucial to ensure that your battery is fully charged and well-maintained.

How Does It Work?

When the breakaway switch is activated, it pulls a pin from the switch, allowing power from the battery to engage the trailer brakes. This process is vital for preventing accidents and ensuring your RV comes to a stop if it becomes detached from the towing vehicle.

Inspecting the Breakaway Switch

Quick Inspection Steps:

1. Check the Lanyard: Ensure that the lanyard is not dragging on the ground and appears undamaged. If you find any signs of wear or damage, replace the lanyard immediately.

How to Test the Breakaway Switch and Brakes

Follow these steps to properly test the breakaway switch:

1. Disconnect the 7-Way Cord: Remove the 7-way cord from the truck. Failing to do so may cause an error message or damage to the brake controller.
2. Pull the Lanyard Pin: Have someone listen at the back wheels while you pull the lanyard pin out. You should hear the brakes engage audibly.
3. Verify Brake Engagement: Move the truck forward slightly. If the RV brakes are functioning correctly, you should feel resistance.
4. Check for Free Movement: If the trailer moves freely, there may be an issue. Contact an authorized RV dealership for diagnostics, and do not tow until the problem is resolved.
5. Reset the Switch: If the brakes engaged properly, push the pin back into the breakaway switch.
6. Reconnect the 7-Way Cord: Finally, reconnect the 7-way cord to the truck.

Important Safety Warnings

• Never Use the Breakaway Switch for Parking: Removing the pin applies constant power, which can drain the batteries and potentially damage the switch and brake shoe magnets.
• Attach the Lanyard Correctly: Secure the lanyard cable to the truck frame, not to the safety chains or tow ball.
• Stow the Lanyard Cord: When disconnecting the RV from the truck, remove and store the lanyard cord to prevent accidental activation.
• Understand Brake Functionality: Remember, the brake system is designed to engage the brakes, not lock them up.
