Trailer Brakes Do Not Activate With Brake Pedal When Trailer is Sitting Still
Question:
I have to get back over to that project and do some more troubleshooting. So, based on answer that I received; " it is possible that the trailer brakes may not apply via depressing the brake pedal while sitting still", what would be the appropriate way to check and see if the trailer brakes are working properly via depressing the foot pedal? Just a reminder, I jacked up the trailer while everything was hooked up, spun the wheels and had someone hit the brake pedal (the tractor had full air pressure), the brakes did not apply. I spun the tires again and had them use the "Controller's" override sliding switch and the brakes locked up immediately. I also learned that the "controller's" green light stays on constantly (even when the key switch is off) and is warm to the touch. This does not seem right to me.

Actually that is a possibility. Proportional brake controllers will not engage the brakes with the pedal unless the tow vehicle is in motion.
Another possibility is the red wire from the brake controller isn't connected correctly. It needs to be connected to the cold side of the stop light switch or the wire that is hot only when the brake pedal is pressed. I would also check any fuses related to towing and replace if necessary.
If none of these ideas solves your problem let me know and we'll continue to troubleshoot.

I just bought a new truck that has one of the Prodigy trailer brakes. My old truck had the same one. As I’m driving it always shows a reading and fluctuates. My new truck does the same thing. So is this normal? I’ve just been turning it all the way down and then when I need them I turn them up and apply manually.

From what I can tell it seems like it only works when I use the manual lever. But idk for sure because if i use the manual lever i can feel it jolt a little. If i use the break it doesn’t do that. It shows a constant output number but it’s only while I’m moving and it’s constantly changing numbers.
