Trailer Brakes Power

Are the trailer brakes powered by the "house batteries" or from the tow vehicle?

Hi, the trailer brakes are powered from the tow vehicle except in the breakaway situation; Then they are powered by the trailer's battery.

Re: Anyone Consider ONLY One Battery

The brakes on our 2012 are connected to the trailer battery.
You can demonstrate this by pulling the safety pin that normally connects to your tow vehicle from its switch while the trailer is parked and not connected to the tow vehicle. You will hear the brake magnets apply.
By the way, do not leave the pin out as this sucks the battery down at a good clip (ask me how I know..).

The brake controller in the TV sends variable voltage to the brake magnets directly by way of the umbilical cord.

Did you start three threads to ask the same question?

It's best to keep a single question to one thread. That way all of the information will be contained in one thread and everyone will have all of the information (assuming they choose to read it) already given if you have follow up questions.

You need charged battery in the trailer to be legal (and safe). The brakes are powered from the TV when it is connected.

The trailer brakes are not powered
by the house battery under normal towing conditions. The power for the trailer brakes is fed through your brake controller ( you do have one of those?) when the umbilical cord is connected for towing. Your house battery is there for the catastrophic incident when your trailer comes unhooked from your tow vehicle then the connection to your breakaway switch is pulled and then your house battery comes into play. Your house battery ONLY sends power to the trailer brakes when the breakaway switch is activated so that it will stop the trailer immediately to keep it from crossing lanes of traffic and not making a bad situation even worse.
