Hi,
I am cutting a USB A-C cable and want to use the USB-C end to connect to a wall adaptor to generate a 5V power supply.
When I cut the wire, there are four wires in the thread, one red wire, one green wire, one white wire and the GND. When the USB-C connector of this cable is connected to the wall adaptor, the measured voltage between the red wire and the GND is ~0.725V,
I assume I need to do some rework for the green or white wires to add the pull up/down resistors. Would anyone advise me what should I do to generate a 5V DC between red and GND?
Thank you!
