BEST MOSFETs testing. Easy way to know if your component (MOSFET ) is dead or not!
Use negative or black lead of multimeter, connect to Source which is the left leg of MOSFETs
Use positive or red lead of multimeter , connect to Gate which is right leg of MOSFETs for 3 second (to allow the multimeter to charge up some voltage on it.
Once the red lead removed, put it on the metallic (Drain) plate of the MOSFETs which is the top of it.
Now you will spot figure on the multimeter display.
Then try to to use one of your finger to link the Gate and Source in terms of shortcut them while holding both red and black of multimeter on source and Drain legs of mosfets together.
You will then see Multimeter stop reading which mean the MOSFET has reacted as a switch.
CONCLUSION : MOSFETs working or is in good condition
