Did the Taylor show any signs of leakage when rated voltage was applied?
I did a bit of digging a round as quite a few people have found ESR meters have difficulty sometimes detecting bad caps.
I also found this which might give you another test option
An old time radio engineer taught me a way to test electrolytic capacitors that is pretty much infallible once you get accustomed to it. He takes the square wave "cal" output of his scope into one of its vertical inputs with a coax jumper and a BNC "T" adapter. A "straight" (1:1) probe is connected to the third leg of the "T." With the probe open-circuited, the scope is adjusted to give a comfortable display of the cal signal. He then connects the probe and ground lead to the capacitor.
What you see on the screen is, a good cap will drag the square wave down to almost nothing. An open cap will leave the square wave practically unchanged. Caps with high leakage or ESR will reduce and distort the square wave, but not cancel it completely. If in doubt, a brand-new cap of the same size can be measured on the bench to see if there's any difference.
My modification on it is to use a separate pulse generator with a 47-Ohm resistor in series with its output. This allows me to "see" what the caps are actually doing at different frequencies.
