So I have everything I need to put together my moonlights but I don't have a multimeter at the moment. All I need to know is, which wire is positive and which is negative on the power supply. One of the wires is solid black and the other is black with a white stripe. Is there a standard for this type of thing or no? I will have access to multi-meter in about a week and a half so, if need be, I can just wait until then. Otherwise if someone could tell me which wire is positive I would greatly appreciate it.
