Have you got an ESR meter?

No?

Very useful devices and can be bought pretty
cheaply these days.

Ok thanks, I'll look into it.

Simple way to test caps.

I have on occasion used the capacitor testers that are on a couple of
my DMMs but they rarely cover anything of any size. ;-(

checks eBay

Is that right, they read up to 100,000 uF?

It's not the capacitance they're testing but the impedance. Low impedance
is vital for correct operation in some applications.
