 Make sure that you have not touched the Gate lead since you turned the device on. Probe with the <span style="color:#FF0000">'''RED'''</span> on the ''Drain'' and the '''BLACK''' on the ''Source''. The expected reading is a short circuit. Then probe with the polarity reversed with the <span style="color:#FF0000">'''RED'''</span> on the ''Source'' and the '''BLACK''' on the ''Drain''. This should also show a short circuit. If either of these shows an open circuit, then the Drain-Source is blown open.
