Get yourself a real mult-meter to test the actual wiring before the
fixture. Don't use inductive probes or gimmicky light bulb testers.
Use a real voltmeter to test the *wiring* first, then you can work on
diagnosing a bad fixture.

What will that accomplish? A real voltmeter has a very high impedance and
will give the same result.
