Hi, I need Apple iPod shuffle 4th Gen A1373 EMC 2400 schematic since my iPod is not charging anymore. It would be also helpful if some one could tell me, what is the correct output voltage of the usb cable, so I could test if my charging cable is ok. I am not sure but I think the usb cable might be the culprit but I can not test it because I dont know the right voltage is should output. When I connect it to pc the red light turn on for 5 seconds and then turns off. PC does not detect it. Any help is highly appreciated!
Sam it will be next to impossible to find any schematic for your shuffle. I am not saying they are not out there, but I have not come across any for the last 5 years. At this time I would at least try to change the battery. That could be the reason for not charging as well as the other issues. There are no guides for it but the teardown on here should help you getting there. This should help you with your cable question.
iPod pin 4 to USB pin C => USB DATA - / Left Channel iPod pin 3 to USB pin B => USB DATA + / Right Channel iPod pin 2 to USB pin A => GND iPod pin 1 to USB pin D => Vcc (+5V)
