    Hi everyone,

    I am new to this site and am trying to diagnose my sisters dead ipad 1. It has no power and does nothing when
    plugged into stock charger (not even battery meter on screen). I tried connecting it to a computer and it does
    not get recognized. I tested factory charger and it works fine, so I tried replacing internal charge port cable
    and still nothing. My question is does anyone know the voltages of the 4 pins on the battery pack, I tested the
    batteries them selves and get 4.05 volts each, but when I test the pins I get strange voltages.

    1-2 = 1.56v
    1-3 = 4.05v
    1-4 = 4.05v
    2-3 = 2.48v
    2-4 = 2.48v

    can someone verify if this is correct. I want to make sure battery pack is ok before I get a new logic board

    Thanks
