To test the wiring on a trailer brake controller is easy; all that you need to is pull the emergency pin on your break-away. If you face any problem with the brake controller, or if it is not working, then the problem is with the brake controller or the problem is with the truck’s connector on the trailer. Like any other electrical device, the trailer brake also has a limited lifespan, some of these brakes work for a long time and some very limited time, that way you can also recognise that the trailer brake is working well.
The steps to test the brake controller are easy; with one particular tool, you required a light tester. Place it on the vehicle body and use it to search the wire that you need to test. Use luminous bulb because most of the time the voltmeters do not stifle enough load to activate the trailer brake controller, this is because the brake controllers are triggered by the magnets that on the trailer, and accordingly a load. That means you can restore the load easily with the bright light bulb. The first thing that you need to check if you think the brake controller of your trailer is simple.
The Electric trailer brakes should be controlled by trailer brake controller, located in the towing vehicle that is close to the driver. It facilitates easy and quick adjustments to the brake controller, and you can make an adjustment for different levels of brake function for different trailer loads. This adjustment controls voltage accessible for the electric brakes, and higher voltage affects the brakes more strongly than the lower levels do. The quick loss of the capability to modulate the altitude of brake application may signify the controller failure. Testing for the failure within the capacity of mechanics and it needs limited equipment.
Watch the brake controller and then push down the brake pedal. The controller display should illuminate and hold comparatively steady reading that should not fluctuate by more than one tenth of a volt up & down. It is also required to turn on the ignition for this step. trailers for sale Auckland
You should also check the fuse to the display of the controller if it does not illuminate. Restore the fuse if it is burned and again repeat the test. If the fuse burns again, then it specifies a short circuit, which you should find it immediately and repair it before conducting further testing of the trailer brake controller.
Check the trailer connector that is located on the back of the tow vehicle using a multimeter. Take some help to hold the brake pedal so that you can look for the terminal that is linked to the blue wire in the connector. In the connector, this blue wire is the brake control wire, and it contains the voltage when you apply the tow vehicle brake. The voltage present in the wire will vary when your helper shifts the adjustment control on the brake controller. If the voltage does not change, or it does not have any voltage that signifies a faulty controller or the blue wire itself is the problem.
