I am testing two high power (1000 Amp) SCR's. I read low ohms between gate and cathode in both directions, on both devices, yet they trigger and pass DC under test OK. Is the internal gate / cathode resistor used in high power SCR's a low value? Or is there a chance they are faulty, yet still pass DC current to a small low voltage bulb when the gate is triggered with 2V, and stay passing current with the gate voltage removed? They are actually used in an AC rectification / current control application when in circuit. Thanks.
