Hey everyone,
Wondering if someone with electronics skills can provide any guidance.
I'm trying to hardwire a dashcam. I ran a 12V to mini-USB converter (came with dashcam) from the rearview area, across the headliner, down the A-pillar, and then into the passenger side fuse box. A pick of a similar 12V-5V converter is:

I'm using an add-a-circuit in a delayed ignition switched fuse (can't recall the fuse number right now but it has a 10A fuse). I attached the red wire (actually black with a red stripe) from the converter to the pigtail.
Then I wanted to test to see if it would work so I touched the black wire to a grounding bolt and promptly shorted my fuse. I double checked all my connections and tried again, burnt up another fuse. I tried one more time, and voila...lost another fuse. Doesn't matter if the camera is connected to the USB or not.
What am I doing wrong?
I should mention that the first time I wired it up I was in such a rush that I did accidentally put the black wire into the pigtail which is a no-no...and promptly melted the fuse of course.
I was wondering if there was a short in the actual converter device. I measured the resistance across the red and black wires that are supposed to connect to the truck's power. It measured approximately 35 Mega ohms...which sounds lke a lot of resistance to me (i.e. it is not shorted)...
Thanks!
