I just cut the og cable a little shorter because there was a crack at the start of it. I tested after for voltage and shorts (that was my first thought) but nothing wrong aside from the voltage output being funny. Now after i tested that i rested...
Today i wanted to reroute/replace my Nintendo Wii u power cable and for some reason the psu (the big brick that outputs 15v @ 5a) doesn't want to turn on i suppose.
I made a test i desoldered the cable i soldered and it went normal about 14V once...
