You can drive an igbt with 12v (i am). It will turn fully on just a bit slower which will increase switching losses and heat. My best advice would be to scope the gate emitter of one of the devices and post a pic on here. If you look at some of my videos you will see my early experiments. The purpose of the fast recovery diode and extra resistor is to aid the turn off (another area of potential loss).
Now, Cole, when you shift the gear and that little needle on the ammeter goes into the red and reads 2000 Amps, that's bad.
