How to Test If Redarc Liberty Brake Controller Is Working

Published 07/22/2024

Question:

Questions about the redarc liberty controller. Havent tried it with the camper yet. When I step on the brake pedal the light wont come on. If I push the knob, the light comes on blue, then fades out. Is this normal? Also, when I use a tester at the rear of the truck the brake power light doesnt light up.

Hey Larry.

The Redarc Liberty # RED24FR Won't light up with the brake pedal if no trailer is hooked up, or if you are sitting still. It's a proportional controller so it needs to detect movement. You really need to hook up your camper to verify everything is working right.
