LED strip light wire issue
Sorry for no diagram, but all multi color led strips are all pretty similar, 4 contact points at each cut point.
A year ago I bought a 5 meter roll of LED lights. The RGB ones with a 14 button remote, 3m backing, and covered by a jell. Yesterday I bought another 5 meter roll to wire up with my old roll, as the controller (little white box that the 12V plugs into and has the IR reciever) came with leads to connect 2 strips.
I plugged them in and they didn't work.
So i got out my multi meter and tested my old controller and the new one. and the results came back opposite.
One controller, I needed the red pin from the multi meter on the +12V line and the black to go on each color to show 12V.
The second, I needed the black pin on the +12V line and the red on the colors to show 12V.
So to me it looks like one sends the 12V up the +12V rail and back down the the RGB. While the other is sending 12V up each of the RGB and back down the +12V rail.
The led strips that belong to each controller are wired the same. so they don't plug and play.
So my question is, Is there a way to get these LED strips to work with one another or will they have to be run on 2 separate systems.
Thanks in advance
