Backup Camera Video Problem

[FloraBama]

To make a long story short my dog chewed through a wiring harness going to the headlamps, left front ABS and backup camera. All the wires have been spliced back with everything working except the video.

The video cable has 4 wires and a wire mesh shield. The wires have been soldered together (wire mesh twisted together) and all of the camera functions (up/down, audio) work except the actual picture--I get a solid white screen.

Before I start looking for a new 50' cable I wanted ask if anyone has any ideas on what might be the problems.

I had a similar problem on our previous MH. Rather than a dog, had a pack rat chew the cable in half under the dash. Got that sucker though. But ending up having to order a new cable. I ran it under the MH and came up thru the tail light opening (took it out). Covered the cable with the plastic roll that goes over wires. Not a hard job at all. We had a Sony cable. Very expensive BTW. Our new MH has a Weldex camera. Hope its finnaly fixed (3rd replacement by Monaco). The Tech said they fix the problem and he put the new fixed camera in for us. We'll see. s/Toby

I also have a Weldex Model WDRV-3067 which is a motorized camera. I want to replace the cable but the Weldex site or any Googles returns anything on the particular model.

Good source for these cables???? Please.

I also had a video camera problem.I ordered a new camera (Side) The new one works intermittantly. I cleaned the connection carefully and re attached .I was wondering if I should Spray with something to make a better contact? thanks

Two wires are for 12+ and 12-(ground) DC (camera power). The other two are your video feed. The braided cable is for radio frenquency shielding, it is also grounded. Usually losing a little braid won't hurt as long as you connected it back together. I think the dog bit through and shorted the 12+ to the grounded braid or to the 12- VDC wire. Check the fuse for the camera. A common mistake is to think that because the monitor has power, so does the camera. It probably does not use the same fuse as your monitor. BTW, how's "Sparky the dog" doing?!!!! Please let me know what you find, would you?

Thanks,

My camera is working -- nothing short of a miracle.

Lesson Learned: weldex.com customer service is very and good and quite helpful. They quickly cross-referenced my monitor model to a replacement cable part number which can be ordered directly from Weldex.

However, the support tech suggested that before ordering a new cablle I should removed the camera and plug it directly into the back of the monitor. The camera has a 18 inch pigtail which is just enough to test the unit without the entire 60 ft. cable.

Well the camer worked fine meaning the cable in fact ws bad. But.... my MH came from the factory with a video cable routed along the frame back to the camera. The original cable which ran through the house was not used so I just figured at some point the factory deemed it bad and ran an althernate cable.

So as a last ditch effort I plugged the camera into the "unused cable and the dang thing worked. And I have no idea why National RV ran the second cable unless one was bad.

I know this is a little confussing but this should provide some pointers on trouble-shooting a camera and using the short pig-tail to plug directly into the monitor.

And BTW, if you're wondering about the dog he is fine and the wife and daughter love him more than me so he really gets away with murder.
