Any A/V gurus here I have a question

[Dolomite_supafly]

I need to figure out how to wire an RCA plug.

 

The bundle coming off the board is 3 wires, red+black+yellow. The red and black power the board and I was told that yellow is for the video signal.

 

Question is I am sure the video signal uses more than just the one yellow wire so which is it, red+yellow or black+yellow?

 

The yellow is the center of the RCA jack so what goes to the outside?

 

This is for a video surveilance camera if that makes a difference.

My wife will be home from work soon and I will ask her. As I am more of the hammer/mallet sort of guy. LOL

Black, you can use the same black wire from the 3 wire plug to ground your video w no issues, done it many times.

Ok.

 

So red goes to positive on the battery.

 

Black goes to the battery and the outside of the RCA plug.

 

Yellow goes to inside the RCA plug.

 

Thanks

Yes sir,that is correct,it's ok for power ground to be shared with video ground. I honestly believe they do that to save money on eliminating 1 wire,as I've had 4 wire mini harnesses in the past.

The camera I am working with only has three pins on the board so I doubt it is to save on wiring, especially when I had to purchase the wiring harness seperately.
