Blue wire for Electric Brake

Does the Blue wire marked 'Electric Brake' supposed to have any constant voltage? Just curious.

Tuff question. I installed mine about 1 1/2 years ago. IIRC, the blue wire was the one that attached to your brake pedal wire so when you hit the brakes it activated the trailer brakes. I never trusted the color of the wires. I always checked each one with a volt meter.

There should not be any voltage on that wire till the brake pedal is pressed and then the brake controller sends a voltage, determined by the settings on the brake controller to the electric brakes. Other wise, the the electric brakes on what is being towed, would be being applied.

Thanks, after reading some Trouble Shooting instructions for my old US Gear braking system, I realized that's how it works.
