Rv camera box

[mrgscooter]

My rv has a box that all the cameras connect to and a single output cable to radio. There's a wiring harness that connects to this box, I'm assuming one of these wires powers the box. Anyone how I can find out what wire is power? I'm trying to trouble shoot why I have no video signal to radio from any camera. Any help would be greatly appreciated.

Do you have an electrical multimeter?
If you do
Do you need instruction in its use?

If you don't have one
Buy one for as little money as possible. Harbor freight $5+- unit is perfect.

Then we can help you.

And
Buy a male male cable connector(or whatever you determine fits the need) while you're there so we can tell you how to jump that box.

Power might not be the issue at all.

Does the radio switch to camera mode when the RV is in reverse? Or a turn signal is activated? But the display has a "no video" message?

If so, the box has power as the trigger function is working. In this case you have an issue between the video out and the radio's video in.

And you can't "jumper" the box as the camera connections are not RCA connectors.

I'll check my 3 to 1 box and see what's needed.

My rear camera has a mic so you hear what someone guiding you back in was saying. We found this by accident as we were driving down the road the wind noise was on radio had to turn volume down. Too bad the Axxera radio could get any stations clear doesn’t matter because speaker are in back and one is blocked by slide when it in.

Our Ace's speakers were in the ceiling and behind the cab area (and the left speaker is above the slide when it is retracted). I added a pair of speakers to the dash (there was plenty of room for them) and re-wired the radio connections so the dash speakers are 'front' and the ceiling speakers are 'rear'. Much better when listening to the radio when driving.

I also swapped out the Jensen radio for a Kenwood. CD's would regularly skip in the Jensen but work fine in the Kenwood.

What is this "CD" you speak of?

Well I couldn't find a double DIN 8-track player.

My four track player is around here somewhere unknown.
If that eight track isn't quadraphonc it ain't diddly.
Cool kid early cassette early adapteer. Hump mount cassette recorder player.
No one without an echomaster reverberation system was cool.


Op needs to post a pic of his video box so we can plan an adapter build/buy and tell him how to use the

If i can find a 5ohm outside TV antenna adapter to an hdmi to run a genesis so we can play toe jam and earl on the led tv,
I bet there's an adapter to let us skip the box for camera testing.
And
Buy this

Aside;
We have never had a radio on in the rv except to test it when initially purchased.
(We enjoy each other's company, keep a hawk-eye out for things to look at while driving by, then discuss them and we just don't need to hear Sweet Home Alabama ten times in a day)

I’m installing my 8 track from my ‘69 Valiant.

With the radio on: if I shift to reverse radio screen switches to camera screen and states "no video signal". Same is true with either left or right turn signal, radio screen switches to camera screen and states "no video signal". I can't just jump across camera combiner box because cables aren't just rca connectors. I've checked the continuity of the output cable to input radio which tested fine. I'd like to get my hands on a description of the wires that are in the wiring harness which goes into the camera combiner box. My next step now is to order a new camera combiner box to see if that fixes the issue.

On mine as I push the button on top it will click thru no front , no rear then one more click and rear camera comes on and turn signals work when activated. The rear camera allows me to drive with rear camera activated but I need sound turned off because wind noise is irritating

Or get any old video display with an RCA video input and a new RCA-to-RCA patch cable and see if you have a good output from the box. That's a much cheaper parts cannon shot.

The box obviously has power in and trigger in from all 3 cameras.
