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.
