Integrated Brake Controller not working
My 05 F-250 is experiencing some trouble with the brake controller. The LCD panel in the cab is functioning, and I'm able to adjust the gain. When I hooked my camper up for the first time, I noticed that the trailer brakes did not seem to be engaging. I turned the gain up to 10 and then started the trailer just barely rolling and engaged the manual lever. It didn't even slow it down. My old F-150 with a Tekonosha P3 would deploy the airbags if I used the manual control turned up all the way. I did hook the camper up to my dad's truck and using his Tekonosha controller the brakes lock up immediately with the manual control so I know the trailer brakes are working. Is there something I'm missing with this controller? Will it not work at low speeds? If something is wrong, should I take it to my dealer, or to the RV shop in town?
Thanks for any help you guys can give me. I wasn't sure if I should post this here or the Electronics forum so I'm sorry if it is in the wrong spot.
