Electrolytic Capacitors--Problem on Amiga Circuit Boards?

[aardvark]

While looking on the web for recommended ways of cleaning motherboards, I stumbled across this site.

While battery issues on Amiga circuit boards are well known and the fixes documented, do we have similar problems with capacitors?

If so, outside of obvious leakage, how do you test them while they're still on the board? :-?

I found another web page which talks about capacitor problems on motherboards here.
They also refer to here and to a Toronto Star article here.

Perhaps most of our circuit boards predate the faulty capacitors, but then again.... :-(

Okay, but no one actually said how to test capacitors still on a board to see if they are within spec.  The "dried out" ones that don't leak anything obvious are the ones I'm wondering about, but of course anything bulging or leaking would be a giveaway.
So if I take out my multimeter, then....?
