Troubleshooting Curt Venturer Brake Controller with Flashing Red Light on Display

Question:

I have a 1998 Ford F150, 4.6. I have install the brake controller 51110 with the wiring harness for my truck. The red light will come on and go off by its self without touching the brake without a trailer connected.

I checked with Curt and the flashing red light indicates a brake circuit overload, or a solid red light means that no trailer is detected.

If the light is flashing that most likely means you have a short somewhere on the brake output circuit, but since there isn't a trailer connected most likely you have a dirty trailer connector at the rear of your vehicle that has a bit of corrosion that is causing a slight amperage draw which is confusing the brake controller. Try cleaning the pins of the 7-way and most likely the problem will go away.
