Hey Kerry I bought a meter the other day to check what part of the cig plug was hot. I had it wired right the first time. As far as the usb, the fuse blows as soon as I plug it in (with nothing plugged into it). I took one apart and nothing seemed burned so i replaced the fuse and it worked in the car
I'm thinking I need to add a resistor or something into the usb to drop the amps done a notch or maybe put a bigger fuse into the usb adapter.
