Re: TESTING MOSFET
Hi, are you testing to know if the mosfet is bad? All you need is your digital multimeter, the you select the diode sign, then you place you meter probes between the center pin and the last pin their will be a reading on the display and if their is no reading you reverse the polarity of the probe, but normaly the gate does'nt read any resistance between the drain or source, but if the mosfet gate is on the meter will display the RDS on.
