okay so what im trying to do is to build a wire from my 9v dvd battery > UA5. the battery is (+) tip (-) outside and the ua5 is (-) tip (+) outside. so basically i have two power adapters which both heads fit and i have the wires cut. how do i know which wire goes to which tip?
on one wire there is a white stip, is that (-)? and on the other wire there is white writing, is that also (-)?
so if the tips are opposite should i connect the wire with the white strip to the wire on the other cable with nothing on it? would that make it so the heads are opposite?
i hope that makes sense, I really dont want to fry my UA5! any help is appreciated
