  • how do you power your dscustoms or digitalww screen?

    Hi Folks - I was wondering how you power your wwdigital or dscustoms 7" touchscreen? I tried searching - but apart from the opus thread i found nothing obvious to my very untrained eye.
    Thanks in advance,
    P.

    Any good 12V source will work. If u have an inverter, you can use the supplied AC/DC adapter. Or, you could plug it into a free 12V DC car socket. Or, you could use the yellow/black 12V leads from the PSU (Preferred).

      I power my lcd through the power wire of my head unit since it is so close. You can also wire the lcd straight to the battery.

        what about fusing the power wire? necessary?

          always a good idea to fuse anything you add to the car

              freestyler, how did you figure out which wire was ground and which was power? Im assuming it can be done with a multimeter, but i've forgeten all i learned in EE class.

                yellow = 12v
                red = 5v
                black = ground

                  I thought there was issues that the unregulated voltage from the car power causes flickers..

                  Is this true?

                    Yeah, its always a good idea to use a fuse. The wiring going to the head unit is fused already but if you wire it straight to the battery its a good idea to use a fuse.

                      The flickering depends on the car and its electrical system. It worked fine in my Qx4. I did so for about 4-5 weeks. But if for some reason their was a power spike, you may fry the screen. You should try to use a regulated power source to protect your investment. I now power the screen from my Opus.

                        I just used my Opus 150Watt.. Cut the plug off the CPU Power (Didn't need it) and then made a wire from that to the screen - 12v regulated, and everything turns off when the computer does!

                          freestyler, i meant how do you find the + and ground wires coming from the screen, not which wires to hook them up to, i do remember some stuff .
