The problem that creates that sign is that the magnet has too much winding in its way or there are frayed or broken wires. The best one that is given off by bad magnets is erratic brake control behavior. This starts with the ability to recognize the signs that there is a problem with the magnet in your trailer breaks. But other issues may arise that are not so easy to find or fix. Just replace the bulb, sand off the corrosion, replace the wires or add a better ground wire and you are done. These are all easy to spot and fix if you know what you are doing. The problems could originate from a burned-out bulb, a little corrosion, broken wires, or even a bad ground wire. When you are having trouble with your trailer brakes, start with the easy issues first. The bad news is that if you do not have a circuit tester, their cost gets close to $100 for a good one. If that is the problem then you need to replace the controller. Now if this is not the problem, then you need to go and check the internal circuitry in the brake controller.

If you use a manual override system to check your brakes, that override bypasses the red wire and applies the brakes on your trailer. You need a circuit tester to help sort this issue out and find the right wire to connect to the red wire. That problem would be a loose, broken, or badly connected red wire in the brake controller.Īlso, if the red wire is attached to the wrong wire in your stop light switch which is located above the brake pedal, then it may be carrying a signal when it shouldn’t. Now if the brakes signal okay and work when you push the test button, then there is a problem with the red wire connection. If you are experiencing no braking power on your trailer when you apply the brake pedal then there is an issue with the brake controller. This may not be a difficult problem to diagnose or fix. Replace defective wires and you should be fine. You have to do a different test to verify that diagnosis.Īlso, you would have to physically look for frayed, corroded, exposed wiring or if the wires are bent, damaged, or loose. Or there may be a problem with the wiring in your trailer. If there is no power getting to the 7-pin using the manual override, then you may have to replace the controller. Then you set the brake controller to its highest setting and use the manual override. If that isn’t the problem, then you may have to test the controller by having someone go through the functions while you use a circuit tester. When it does, you need to clean that corrosion off. This little defect can hamper even the best braking systems. If that fails to materialize then you need to check for corrosion. This part must tell the trailer how much braking power is needed.Īnother duty the brake controller has is to actually send the power to the trailer brakes. You will need to add a brake controller to the system. Trailer Brakes Not Working But Lights Areįor 7-pin brake options, this may be a common problem as there is one additional part you will need to make sure everything works right. When one set of brakes gets more power than the other then the controller is bad and you probably need to replace it. This issue you may not be able to do yourself as it requires checking the current flow and the controller to see if both are working properly. Finally, there is a lack of electrical power getting to your brakes. Once you clean them you should feel a difference. You just need to clean the brake drums and calipers. However, the solution for this situation is easy. Electric brakes are known for being a bit rough or vibrating a lot when you apply the brakes. Electric brake drums need to be adjusted manually while regular car brakes can adjust automatically.Īnother common problem will be the lack of a smooth braking operation. While this may seem to be a difficult problem to solve, all you need to do is adjust the brakes. Next will be the electric brakes getting too hot as you drive. While you simply tighten the wire nuts or screws for the previous problem, the connectors need to be sanded with some good fine griot sandpaper to get them clean again. Then another common problem will be dirty connections.
Loose nuts, wires, and screws can cause you headaches until you find the culprit. This seems to happen more with the 7 pin plug than the 5 pin option but it can happen anywhere. The first common problem you will find with RV trailer brakes will be loose connections.
