    See attached.

    Review the first 2 x DCIN mosfets.

    First, remove all power. Then configure the meter in resistance mode.

    Confirm which pin is # 1 on the mosfet. It should be in the TOP LEFT corner.

    Pin # 2 will be immediately south of this pin -> 3 -> 4.

    Pins 1-2-3 will be shorted on the circuit board. Confirm it so you have a proper orientation of the component.

    Check:

    source (1-2-3) & drain (5-6-7-8)
    source (1-2-3) & gate (4)
    gate (4) & drain (5-6-7-8)


    Post the resistance values of the first mosfet. Repeat the test for the 2nd mosfet.
