Breakaway trailers are used for hauling heavy items like boats, RVs, and cars. A breakaway system is required by law in most countries to ensure that in case the trailer breaks free, it would come to a stop immediately. The breakaway system needs a battery to function, and this article will cover the 12-volt battery wiring diagram.
What is a Breakaway System?
A breakaway system is an emergency braking system that activates in case the trailer becomes disconnected from the towing vehicle. The system applies the trailer brakes if it detects that the tow vehicle is no longer attached. It prevents the trailer from rolling away at high speeds and causing an accident.
The breakaway system consists of a battery, a switch, and an emergency brake controller. The switch is triggered when the trailer becomes disconnected from the tow vehicle, and it sends a signal to the emergency brake controller, which then applies the brakes using the battery power.
The Importance of a Breakaway System
A breakaway system is essential for safe towing. It ensures that the trailer brakes are applied immediately if the trailer becomes disconnected from the towing vehicle. Without a breakaway system, a runaway trailer can cause significant damage to property and potentially harm people.
Many countries require a breakaway system to be installed on all trailers that exceed a specific weight. The breakaway system is a legal requirement in most areas, and failing to install one can result in fines and legal action.
12 Volt Battery Wiring Diagram
The breakaway system uses a 12-volt battery to function. The battery needs to be charged and maintained to ensure that it works when needed. The wiring diagram for a 12-volt battery in a breakaway system is as follows:
| Wire Color | Function |
|---|---|
| Black | Negative (-) Ground |
| Red | Positive (+) Charge |
| Blue | Switch Trigger |
| White | Brake Controller |
The black wire connects to the negative (-) battery terminal, and the red wire connects to the positive (+) battery terminal. The blue wire connects to the switch that activates when the trailer becomes disconnected from the towing vehicle. The white wire connects to the emergency brake controller.
Battery Maintenance
The breakaway system’s battery needs to be charged and maintained to ensure that it works when needed. The battery should be charged at least once every six months or as recommended by the manufacturer. The battery should also be inspected for damage and replaced if necessary.
It is recommended that the battery is stored in a cool, dry location, and that it is kept away from direct sunlight. The battery should also be disconnected when the trailer is not in use to prevent drainage.
