Just installed a Valley Oddesey brake controller. The Blue wire from the controller has 12V on it all the time, regardless of whether the brake pedal is pressed or not. Is this normal ? I double checked all the wiring and it is correct. This just doesn't seem right to me and I can't remember if I ever checked this on my last install, which worked fine. I guess I could hook the trailer up and see what happens but I thought someone might have knowledge of this.
I don't have an Oddesy controller but I have installed several controllers on my PUs over the last few years and none have had a continually hot line to the trailer.
I just went out and double checked the line on my new PU and it is only hot when the brake is pushed.
If it remains hot when the trailer is hooked up you will activate the magnets on your brakes
or if you are parked you may run the TV battery
I would give the controller manufacturer a call to be sure.
