I developed this circuit in order for it to be connected to 4 ipads at the same time the current they use to charge when they are on low battery goes around 1.8Amps, That its working as intended, however the part that has the led indicator for a blown fuse indicator doesnt seem to be working
the female headers are connected to a dual SUB female port which are used to connect the lighthing connector, however after removing the fuse the current should flow through the led and 470 ohm resistance , and yes i have a voltage of 3.5v in each led but it doesnt seem to be enough current for it to turn on , i would like any advice about this topic
Pins 1 and 2 carry the 5volts to each usb female port
