I have an 04 F-350 SRW CC. I have an Alpine 7in indash flat screen with a flush mount back up camera in my bumper. The camrea lasted 9mo not bad for a $30 camera. Well I ordered a new one and went to put it in and I am getting a very fast scrolling on my screen. I am stealing power for the camera from the 12v constant on the tralier harness. This is the process of elimination I have done so far. I have used a different camera that has its own power like a video camera and used the same video cord at the back of the truck and the screen looks perfect. So its not the video wire. I then tried the camera with long aligator clips right to the battery still using the video cord at the back of the truck and its still has the bad scrolling it almost looks like a ground loop. I then took the camera to the glove box where I have an Aux input to the screen for like an ipod and used power right from the batter to power the camera and still have the bad scrolling. A picture comes up so the camera is on but its so bad you cant really see anything. I called the company thinking bad camera and they sent me another free and told me to keep the old one and the new one is doing the same thing. So I am thinking its not the camera since both cameras are doing the same exact thing. The only other thing I can think to do is isolate the ground from the radio right to the battery as well but why would this start all of a sudden. Camera worked for 9mo then died all together now this. Any other ideas that I can do to try and figure out this issue? Really want to get it working as it makes backing up to the trailer so much easier and is nice to turn on while going down the road to see the tounge make sure nothings coming apart.

Thanks Ryan

 

I'm thinking the cameras - both - are malfunctioning. Everything else tests OK. The only assumption in your logic is the cameras are fine since they're both doing the same thing. The only thing left to test is either/both new cameras on a different power source & monitor. I think you'll get the same result.

Let us know.
