The first step on how to test an electrolytic capacitor is to compute the value. Without understanding the capacitor’s value, you won’t realize if a capacitor is good or bad. Keep in mind that these values come in the unit of a microfarad, nanofarad, and picofarad.
Most of our aluminum electrolytic capacitors can withstand test conditions imparting peak vibration accelerations of 10 g’s. More specific limits are shown in the specifications for each capacitor series. Frequencies are usually in the range of 10 to 2,000 Hertz. We ofer some series that are specially constructed to withstand testing up to 80 g’s.
If aluminium electrolytic capacitors without the solvent-proof construction are present on the circuit board, alcohol based solvents are recommended for cleaning. In this case, solvents such as methanol, ethanol, propanol and isopropanol should be used. Normal tests show that any detrimental effect is eliminated.
The manufacturers of aluminum electrolytics offer a myriad of different types, most identified by a 2 or 3 letter code. This is usually printed on the side of the capacitor body, along with the logo of the manufacturer. As an example, I've pulled the capacitor below from my "stock" to identify and look up.
Read from the LCD the capacitance value. Set your multimeter to a higher range if you like to check the capacitor. For instance, the meter should be set to 2000 microfarad if you like to test the 470 microfarad capacitors. If you like to measure on the non-polarity capacitor, then you can attach the test probes on either capacitor’s leads.
Fortunately good designers don't use aluminum electrolytics in sensitive locations, and paper/oil caps are uncommon these days. You'll almost invariably have to remove capacitors from the circuit to test for leakage because you don't want to expose the rest of the circuit to the voltages involved.
