>" ** Not for ESR it isn't. "   
      
   True, but a circuit's tolerance for ESR varies widely. A 100 uF with 5 ohms   
   ESR might totally upset one but work fine in another.    
      
   The absolute cheapest way is to just get a test cap that is a low rating, say   
   22 or 33 uF at like 350 volts and bridge it across existing caps at the bottom   
   of the board. totally hillibilly and don't forget to discharge i t every time   
   you use it in    
   another place on the board. It also won't detect a short, but it did work for   
   many years for me and many others.
