The high Q factor due to low inductance with this type of test could
seriously damage either the cap or the power xmfr.  Don't do it this way!!!

Use a DC uA or mA meter in series, rectify output, and look for excessive
leakage current to ground.  I've designed a special probe to do this which I
will share with you if you send a SASE to my address.
