    You're right.
    I must have had the wrong PDF open. :/

    I don't have a fake charger here unfortunately.


    /taps fingers on desk.
    I'll have to try make a plan somehow...

      Check for shorts on the DCIN bus and PPBUS. Also get a fake charger for testing, they are sometimes handy.

        Dead Short. As in 0.000. :/

        How do I work out where the short is?
        Guessing I remove a component in the middle somewhere and see which side still has the short then repeat?

          In Diode mode on R7005;

          ::1 = 0.000v
          ::2 = 0.004v

          So would this mean the short is on the pin 1 side?
          (trying to make sure I'm doing this right)

            R7005 is on the PPBUS not DCIN. But I guess PPBUS is shorted now. Measure in Ohms the resistance to GND on PPBUS

              0 ohms on Pin 1
              10 ohms on Pin 2

                Short can be anywhere on the bus, inject voltage and see what current does. Start low cause the short is pretty low Ohm so should draw lots of amps quick. I expect something in the ISL area to heat up as that was messed with.
