how to test IGBT?

Check for no conduction pin-to-pin on each device. Get a 12 volt battery and attach it to each IGBT in succession - neg terminal to source and pos terminal to the drain through a470 ohm resistor. A meter across the device should show 12 volts. Usa a clip lead to jump +12 to the gate. The meter should show very nearly 0 volts, meaning the IGBT is on.

Repeat for the other IGBT's.
