Landon,

Put your meter on ohms and measure between the drain and the source. These
are the righthand two leads. You should get a high reading, either no
reading or high megohms. If not, it's shorted, the usual failure mode.

I am trying to test two RFG70N60 Mosfets, with my meter set on testing
diodes one Mosfet comes up with a reading of 0.001 the other 0.003, this
seems kind of low.

These are both out of a UPS that is having problems, does anyone know what
the readings for the Mosfets should be? I emailed Fairchild
Semiconductors but they never replied.
