stan2004 posted:Depending on how long you touched the wire(s) to the heater resistor (with it shorted to the chassis), there's a chance you blew the FET again.Specifically, the heater resistor shorted to the chassis provides a circuit to AC track voltage (relative to the DC common in the PS2 circuit board). FETs are essentially DC devices and don't like AC voltages.
The FET isn't all that fond of the high currents a direct short to the track would yield either.
