Hi All,
I have just installed a rear view monitor in my car and a camara on the rear of my caravan. When working the picture on the monitor is not too good. I have checked the voltage at the camara from the main supply and it is 13+ volts and at the camara 13+ volts as
well but on testing the connection at the monitor from the camara I only have 3 volts. I do not know if this is voltage drop or normal as I do not have a manual for this unit. Any advice would be appreciated

Ray, what happens if you plug the camera into the screen using a much shorter cable?
Do you experience the same problem? It may not be the power supply or the cabling but a faulty camera.
Also, have you tried plugging another camera or video source into the screen to see if it the screen?
cheers,
Sam.

"but on testing the connection at the monitor from the camara I only have 3 volts"
- so you are running 12volts from the car, to the camera at the back of the van, then forward again to the Monitor ?
The monitor will draw more current than the camera. You should be feeding the Monitor directly from the vehicle.

If you are measuring the Video signal from the camera then you should be measuring AC, not DC. It's hard to predict how a multimeter will respond to Video signals, but you should something less than one volt.
Substitution is the best approach.
Do you have another TV set with Video input that you can connect the camera output to ?
Do you have a video camera or DVD player with Video Out that you can connect to the Monitor?

Whilst there has been attention paid to the power side of things it seems to me that the picture is the issue here?
Check the video settings on the LCD monitor as you usually have at least two input settings and they will be identified in the manual but as you don't have one perhaps a
check with the manufacturer's website and a phone call may not go astray. Also
check the camera connections themselves as the pin connection can sometimes become damaged.
Length of cable should not be a problem with video quality unless the cable is damaged. I run a Poron infared colour system on a 120 Prado with no problems at all.
Enjoy the chase
