Troubleshooting Redarc Tow Pro Liberty that Only Works with Manual Override Lever

Updated 03/13/2023 | Published 03/11/2023

Question:

I just installed the red arc liberty pro I. My outback wilderness. I get the breathing blue light when nothing is connected. I hooked up the trailer and I had green/blue flashing. Drive around for 15 min and still green blue flashing. When I push the manual option on controller it works. My concern was , maybe I didn’t get a good splice on the brake switch wire. That’s why it hasn’t configured. Could that be the case or does it need more time driving around ?

It does sound like the brake output circuit is not connected to a 12 volt power source that only sees voltage when the brake is applied. I would verify both the connection to the circuit and that the circuit has voltage when it needs to have it.
