A quick check is just to measure the voltage on the capacitor after the
unit
is unplugged - if the voltage holds at near say, 4 volts for a period of
time, then the cap is "probably" OK. This does not guarantee that the cap
doesn't have some more subtle problem, like going down after a couple
hours
or days when it should hold up longer, but that is somewhat unlikely, and
as
another poster said, the cap is fairly cheap. One might just want to
replace
it for good measure.
