How do you test an electric brake magnet?
To determine if a brake magnet has an internal short, touch the base of the brake magnet to the negative post of a 12-volt battery. Then, connect one of the brake magnet wires to the negative lead of a multimeter and the positive lead of the multimeter to the positive post of the battery.
What to do if your brakes are not working?
If the problem still persists after checking each brake assembly you will want to work your way up the wiring from the trailer to the brake controller. Begin by inspecting the wires from the brake assembly up to the trailer connector for any cut or frayed wires.
Why are the brakes not working on my electric trailer?
This switch is designed to apply the brake if the trailer should accidentally become disconnected from the tow vehicle. But on occasion the lanyard will get pulled hard enough to close the contact in the switch and apply the brakes. Noises in the wheels of trailers equipped with electric brakes are caused by a mechanical event.
What happens when no power is found at brake controller?
If no power is found at the connector, the problem is in the wiring between the connector and the brake controller. Check junctions in the wire back to the controller; these tend to become corroded and fail to carry current. If power is found at the controller it’s time to move on to the trailer.
Why are my brake magnets not working properly?
A bad ground connection could be causing your problems. You will want to check to make sure each brake assembly has a good ground connection. If the brake assemblies are not new, you will want to inspect the magnets. If the magnets have windings or wear marks, the magnets are bad and will need to be replaced.
Is there a problem with my electric brake?
If both wires are positive then there is a fault in the wiring of the plugs If this test is correct, then check the second wire, this has to be an earth, (or -). this can be done by connecting the test lead between the two wires , the test lead should light up. If this fails there is a problem with that earth wire, broken, disconnected, loose etc.
Why does my brake controller not work when I press the brake?
It connects to the wire on this switch that carries a signal ONLY when the brake pedal is pressed. It should not have a signal at any other time. Use a circuit tester, like # 40376, to test the wires. If your brake controller red wire is not connected to the correct wire, or is loose or broken, this would cause the problem you are experiencing.
Why are the brakes on my etrailer not working?
If there is a bad ground connection the trailer brakes will not work. Next, check the brake controller wiring. Sever the blue brake output wire, leaving enough room to splice it back together when testing is done and then apply the manual slide.
How can I tell if my brake plugs are wired correct?
If you think the plugs are wired correct, you will have to trace all the wiring from the brakes back along the axles & to the chassis as there will be joiners where the wire splits & goes to each wheel. Sounds like a earth prob to me so all connections need to be checked.
