To determine if it is just the light itself that is out, use a circuit tester like # PTW2993 to probe the black wire coming out of the back of the brake controller. The vehicle might have to be turned on. If it shows power and everything works as it should, then you know the light is out. If there is no power, there is another problem.

First, with the Tekonsha Voyager, # 39510, and your 2000 Ford F-250, you should be using wiring harness # 3035-P. I have included a link to the installation details for this harness. You will see a diagram that shows how the connector that attaches to the truck is pinned out.

If looking at the face of the connector the bottom left pin supplies power to the brake controller. Make sure that matches the connection point on the truck using a circuit tester like # 3808. The harness on the truck is located under the dash near the center console. If looking at the face of the truck side connector the bottom right pin should show 12 volt power. You may or may not have to have the key turned on.

If everything is connected properly but there is still no power to the controller, check for the fuse associated with the 12 volt power supply for the controller. You can also make sure that there is a good ground connection at the brake controller and also at the trailer and vehicle side trailer connectors Clean out any dirt or corrosion you find.

You can then unplug the brake controller for 30 seconds or so then plug it back in and go through the set up process as if it were the first time. I have included a link to the installation details for the controller for reference.

If you have tried all of these things and still have no power to the brake controller then there is something wrong with the internal circuitry of the controller and it will need to be replaced.
