The capacitor should have a very high resistance (out of a typical DMM''s range). To determine the value of a large-ish capacitor without an LCR meter, charge the capacitor up to a known voltage and connect it across a voltmeter. The capacitor will begin to discharge through the voltmeter''s 10MOhm input impedance. Record the voltage value over time.

Learn MoreRe: New Capacitor Brands, Good or Bad? Good quality general purpose caps used intelllligently can last a really long time. I''ve seen GP caps that had to be replaced that were 30 years old. The impression I get, though, is that GP caps commonly used in PSUs are not good quality, except for higher end PSUs.

Learn MoreIf the capacitor shunts the supply circuits (see schematic diagrams), the capacitance may be larger than the capacity of the original capacitor. If the electrolytic capacitor is in frequency-setting circuits, it is desirable to install a new capacitor with the same capacitance; I think no other substitutions are needed. P.P.S.

Learn MoreWhy do we need to Test a Capacitor? When a capacitor is placed in an active circuit (a circuit with active current flowing), charge starts to build up in the capacitor (on one of its plate) and once the plate of the capacitor can no longer accept any more charge, this means the capacitor is fully charged.. Now, if the circuit demands this …

Learn MoreTest a Capacitor with an Ohmmeter of a Multimeter . A very good test you can do is to check a capacitor with your multimeter set on the ohmmeter setting. By taking the capacitor''s resistance, we can determine whether the capacitor is good or bad. To do this test, We take the ohmmeter and place the probes across the leads of the capacitor.
Learn MoreThe base of a good capacitor will sit flush to the board, and the cap should be at a near perfect 90-degree angle to the motherboard. Not all broken capacitors will bulge, swell and burst, however.
Learn MoreIf the value is close to or slightly lower than the initial voltage reading, then the capacitor is good. This means that the capacitor can retain a charge and store energy for a long time. If the value is much lower than or zero, then the capacitor is bad. This means that the capacitor is leaking or has an internal short circuit. Conclusion
Learn MoreIf the speakers sound good the capacitors probably aren''t bad. You can measure them with a simple capacitance meter (though you may need to disconnect one end). As others have mentioned, ESR may have increased but if this happens the capacitance almost certainly will have changed too. Values ±10% should be considered good.
