How can i check for dead fets and igbt's with multimeter?

Tnx

Measure resistance between drain and source(2. and 3. pin). If fet is good, than resistance is high(more than 1Mohm).

Does this counts for IGBT's too?

Can I test the output pin of igbt with dvm or led with serial resistor?

I use an LED driven from the +5V supply into the IGBT.
