That may not be strictly true. If it's a Bob Parker design flyback tester
(now reworked and rebranded by another company), then it actually 'rings'
the tranny, a test that shows up most common defects such as shorted turns
on the primary, and short or leaky diodes in the HV stack.

With any of these flyback checkers they will not show high voltage
breakdown, or critical problems with the flyback. This is only a
simple test! I have been through this!
Oh, I don't dispute that a BP will not pick up problems such as HV
breakdown, Jerry, but that is usually - or at least mostly - self evident in
that you can see the miniature lightning flying out of the pin hole, or
smell the ozone being generated, or see the effects on the screen as
brushing, or hear the effects on the audio, or even just hear it physically
hissing. The only point that I was making is that the BP unit is not a
'simple' reactance tester, but does a test which better simulates the
conditions that such a tranny operates in, when doing its normal job. Almost
any deviation from its correctly servicable parameters, will alter the way
in which the tranny rings, which will be picked up by the tester. Of course,
the results are open to a degree of experience and interpretation, in much
the same way as those from an ESR meter are, and a new, or at least 'known
good' tranny is useful to compare by, but never-the-less, the BP is a useful
tool even on its own, for picking up "most common defects", which is all I
was actually saying ...
