The lights don’t turn on when I connect them directly to DC power(alligator clips to a car battery), but do work if I connect them to my wall outlet using the DC converter. I measured 12.35V DC at the plug going into the control box in both situations and even measured 12V DC at the other end of the light strips in both situations. Why can’t I get them to work without the AC to DC adapter?
