Hi Spykez,
I'm afraid I'm too late.
I believe your lead is soldered wrongly.
Nevermind about frayed wires - I believe they are just some of the earth or shielding from the black wire, quite normal, and as long as they aren't touching any of the metal of the other 3 are ok.
Got my Wiz yesterday, my USB lead didn't work. I took it apart, my red lead wasn't connected! :wub:
I soldered it, it works.
I took photos of mine to show my black wire green wire are reversed to yours.
Sorry for poor lighting. The same side as yours is showing on the first 3.
For any that need to take apart the USB lead at the Wiz connector end
On the opposite side to the 2 screws, close to the connector, is a clasp on each side.
Use the smallest jewel flathead screwdriver - or a blade I guess - to gently open one at a time.
