    How can I test these caps?Can I use a Megger /Insulation Tester ? Can this cap be charged by the Insulation Tester to 4000 Vdc and then read the resistance to calculate leakage current?I have a Digital Insulation tester that does AUTOMATIC DISCHARGE,will It damage the tester?OR any advise on how to perform a test on these caps.Thank you.

    have you tried using an ohmmeter, the fluke series of DVMs are good

    But they apply less than 5V to the capacitor when testing leakage in the auto-ranging "Ohms" position. Mariusmul is concerned about how much leakage his capacitors have when they are charged to 4000V.
