Looking at the pic you posted of the soldered wires sitting on your work table, it just looked like you stripped the wires far back. Especially the red one. I thought maybe the solder was creating a short. It is better to strip the cable's outer insulation back far enough so that you have plenty of Red, White, and Shielding cable to work with which allows the solder connections to be away from each other and taped well.
I'm not implying this was not the case, it just looked like they where very close in that picture.
Luckily for you, I am at work now. I will show you what I mean. One minute.
