Thomas McGhee has desinged a Digital Capacitance Meter, I guees it still in list archives or try http://www.pic101.com/mcgahee/. Anyway, I don't know what do you mean with 'check'. ie, externally, when you see a case poped up just replace it, or if it isn't near heat sources but it warm up, check polarity or replace it. Use the finger.
