6800uF @ 63V. It is not the size of the capacitor, but the rate of discharge that tells you whether it's good or bad. This is called 'RC Time Constant'. In short-- Charge a capacitor to a known value-- like 1V. Let it discharge through a 1K-Ohm resistor, and measure the length of time it takes for it to discharge, and divide by 5.
ESR stand for equivalent series resistance. What happens to a bad capacitor is that its ESR value changes. The change in ESR is totally helpful when determining with 100% sure if the capacitor is bad or good. Usually a bad capacitor can doge the visual inspection method as well the capacitance measurement method.
The first method is a visual inspection. The second method is using a capacitance or multimeter to verify its capacitance value with a given tolerance. The last one is by measuring the ESR value of the capacitor. Some of the above methods are applicable for off and in circuit testing as well.
Check the multimeter reading. If the capacitance reading on the multimeter is close to the value printed on the capacitor itself, the capacitor is good. If it’s significantly less than the value printed on the capacitor, or zero, the capacitor is dead. Know which caps function or fail in a batch.
Large capacitors! First off, yes I'm aware of the safety concerns here... Large capacitors can have deadly amounts of voltage stored, and should be handled carefully and knowledgeably! My question: is there a reliable process for testing a large capacitor?
