Furrion rear camera

Originally posted by CharlieM David, You should recheck that 7-pin connector. I don't know what TV you have but most all newer ones switch power to pin 4 with the key switch. With the ignition off and the trailer disconnected there should be no voltage on pin 4. If there is you can run down the TV battery while camping if you leave the TT plugged in. If you find the line is not switched it may be miswired, especially if the connector was an add on. It's worth a fix if it's wrong.

   There is not a power source from the ignition switch at the back of our truck. It has the factory tow package and the seven pin connection always has power for trailer when connected. The truck has a safety feature if the head lights are left on or interior dome light is left on after a short time power will be turned off to those lights so they will not drain the battery. But the factory seven pin connection is not included in that safety feature.

  I finally got around to connecting the rear camera on the back of our truck cap and I have a problem. The camera works connected to the interior dome light of the cap. But when I connect it to the reverse lights the camera will briefly come on and go off again. I checked the polarity and far as I can see the wires are correct. The camera has a blue light showing that it has power but it has no signal to the monitor. But has a continuous signal to the monitor when connected to the dome light. All I can think of is the reverse lights are causing some kind of interference with the signal. I am calling Furrion tomorrow and hopefully will get a answer to why there is no signal when camera is getting power from the reverse lights. Puzzles me!   I just thought of this maybe it is not getting the proper voltage or amperage from the reverse lights.  That was it, I removed the reverse light from the rear tail light now the camera works with a signal to the monitor. So my guess is with the reverse light burning it was taking the power away from the voltage or amperage needed for the camera to send a signal.

   I have a question for a electrical engineer what does it mean by a electrical current being intermittent? I connected our Furrion camera to the reverse lights and the camera has a blue light that shows the camera is getting electricity but on the receiving monitor the picture goes on and off. I then connected the camera to the tail lights and the same thing the picture goes on and off but when I connect the camera to the interior dome light of the fiberglass cap on back of truck the picture is good no problem. I called Furrion and was told the electricity to the reverse lights is intermittent and that the camera was not designed to work from the reverse lights. And was told it was designed to work from the running lights. What am I not understanding? Is the electrical current transmitted in a different way to the reverse lights and tail lights?  

   offgrid I understand what you are saying but the reverse lights or the tail lights remain on and the little blue light on the camera remains lit but the picture on the monitor turns on and off. But changing the electrical power to the camera from the dome light the picture on the monitor remains constant. The only thing that's changing is the source of electricity, the camera and the monitor both remain in the same location. I will call Furrion tomorrow there is something I am not understanding and when the tech at Furrion told me the other day the power was intermittent he may not of understood. Eventually I will get it figured out may end up doing what CharlieM said and that is to run a wire from ignition accessory switch back to the camera.
