How do you test an electric trailer brake controller?
Testing the brake controller is fairly easy. Sever the blue brake output wire near the brake controller leaving enough room to reconnect it and then apply the manual slide. Using a circuit tester like the Quickee Tester, part # 3808, you should get output to the controller side of the wire you severed.
Why is my trailer brake controller not working?
This sounds like the trailer brakes are not receiving the signal from the brake controller when you apply the brakes.

The red wire needs to attach to the stop light switch above the brake pedal.

How can I Test my Trailer Brake Controller?
Make sure the truck and the trailer side connectors are clean and free of corrosion inside and out. You can test the brake output pin and it should only show power with the manual override. If it shows power any other time then there is a short somewhere between the connector and the brake controller you will need to track down.
Can a brake controller be connected to a positive battery?
Verify that the white brake controller wire (ground function) is connected to the negative battery terminal. Verify that the black brake controller wire (12V power function) is connected to the positive battery terminal with a 20 or 30 amp circuit breaker installed in line.
