No power to backup camera

[DWGERLI]

The camera is powered from your truck via the trailer running lights.

Marker or head lights have to be on from the truck.

Did you check for voltage at the rear camera plug? I agree with the adapter, you need it! I found the same issue with my camera. What was happening was the plug was getting kinked when closing it up. I used a dremel tool to make a little extra room for the cord and I have no issues with it. Good luck.

Why is there no power going to back up camera? Breakers and fuses are all good .

Agree with those that have mentioned the adapter that goes between truck outlet and the cord for the RV. Can’t explain what that adapter does, but it solved the problem of inoperative backup camera. My tow vehicle is 2021 Chevy Silverado 2500 HD. My faint recollection of what I was told when the matter was diagnosed and the adapter was purchased (which was not inexpensive), is that the adapter corrects and modifies the power from the vehicle with all LED lighting and the camera that can’t handle that sort of power source. Again a faint recollection of the explanation. All that said, you do need to have the truck lights turned on to power the camera and not just DRL’s.
Best of luck.

I have 2021 GMC. I had same problem of camera not working. It took several months before they got it figured out. I had to use an adapter, pictured in previous post, to make the camera work.

So, to reiterate, angiecopley, what year and kind of truck to you have? I have a 2021 Silverado 2500 and as jkwilson said, GM uses PWM for their lights and my camera didn't work until I started using the adapter in txloser's picture. Or at least it wasn't consistent without it. My cameras won't fire up with only the DLR, I have to turn on the lights (or at least the running lights) to make it work. If you have a recent GM, have you tried to measure the voltage directly out of the trailer plug of the truck? Note that you may get a reading that is less than 12 volts since it's PWM. If you can answer those questions we may be better able to help.

If you have a GMC or Chevy, they use a power management system. Without the modification to the trailer lamp module or the Lippert adapter, the camera will not work. This is on 2019 and newer GMCs. Not sure if the newer GMCs have had this problem corrected.

I tested mine and it worked, But now I'm going to plug it in again just to be sure. Strange too, as my Brother in Law has a 2022 GMC and has never said anything about the camera not working. I never asked either so....

Probably referring to this adapter. My last two trucks have required this to view the camera.

Can you (or someone) post a link to this adapter? People may find it useful. Never mind, found it on eTrailer

Or if your vehicle has mandatory daytime running lights like we do in the great white north, you’ll always have power!

Doesn't work that way on my truck.
