Replace Micro USB plug at the end of the car charger cable?
drawing.pdfOkay, we have a number of these old chargers lying around that have broken over the years. I decided to fix them all. So I went online and found the little connectors. Got 12 of them, figured I would make sure to have enough.... Oh, almost forgot, this is for Samsung Galaxy S4 and S5 phones.
Well, I can't seem to get any of them to work. I just finished trying for the 6th time.... I think there may be a wiring mistake I'm making, or else there is supposed to be a SMD resistor between pins 4 and 5 (at least 200 ohms?).
Can somebody help me out and tell me what I'm doing wrong? I always test after finishing, +5VDC between pin 1 and 4 or 5.... I've tried jumping pins 4 and 5 as well as wiring to each individually.... the phones charging indicator doesn't say it's charging, but the phone does recognize it being plugged in. When I was trying only pin 1 and 4, the phone indicated that a USB cable was plugged in...
Thanks in advance!
