12 volt dc jack and too low guage wire connector

Asked by pheidius in Home Theater Wiring & Accessories, Miscellaneous Hardware, Projectors

I bought a DC jack already connected to a wire set. It exactly fits the 12 volt out in my presenter. It has a black and white wire and a black one. I soldered the black and white to the red and the black to the black, switched the presenter down and the screen did not lower. So I reversed the soldering scheme and still no go. The electricians who wired my room ran 16 guage wire over some thirty feet of drop ceiling. Is it possible that the the scale of the jump between like(I am guessing here) 28 gauge to the bigger wire and , considering the length of the run, means that the 12 volt signal just gets attenuated over the distance.
