EDIT: The problem was caused by me not properly grounding the black cable seen in the last picture.
I'm trying to wire my front dashcam via the front fuse box.
In my fuse box, F46 is the fuse that allows for 12v power (via the cigarette lighter).
I bought a fuse connector that allows me to tap power so I can connect the adapter wires to the fuse.
When everything is wired up, my dashcam won't power up.
Checking with a voltage-meter I notice that the USB Mini connector (coming from the adapter) does indeed has +-12.2Volt on the outer pin. (Shouldn't this be 5V?)
I am absolutely sure that the adapters work. I used them in my Toyota GT86. Back then they were hardwired to the fuse itself (cable jammed in fuse box ?)
So, I am really confused why the dashcam just doesn't want to power up.
Things I tried:
- Using a different adapter
- Using a different dashcam
- Checking for cable breaks
- Making sure the power is still turned on (within +-6min) by checking if my phone still charged via cigarette lighter USB charger.
- Making sure the dashcams work as intended, via cigarette USB charger it does indeed.
My Dashcam: Viofo A119
Fuse connector:
Adapter with low-voltage protection:
Red and black wire coming from 1 side of the adapter (should be wired to fuse):
These wires are twisted with each other and connected through the blue socket of the fuse connector (see above).
