IF the resistors got hot they had to see a lot of RF power like the IRG510 oscillating.
to test them I use a light bulb (12V up to 1A) and drive the gate with? 0 to 5V
At 5V the light should be full on.? IF the gate is grounded to source and the lamp
lights check to see if there is a Source to drain short.
