Bottom line, the first rule to
doing electrical work is to TEST ALL WIRES, even equipment grounding
wires, for voltage with a known to be good tester.

The most important part of this sentence is the last five words: "known to be

Before using the tester to verify that a wire is dead, test it on something
that's supposed to be *live* to make sure it lights up / reads voltage /
whatever. EVERY TIME.
