I have electronic devices from 1990 and I know that these devices that have not been used for a long time cause faults and depolarization in the electrolytic capacitors, is it necessary to use these devices in the interval of 1x a month to preserve the electrolytic capacitors from failing due to disuse? are used electrolytic capacitors manufactured since 1990 and assembled in electronic circuit
You can frequently check the capacitor with an ohmmeter range multi-meter without unplugging it. A good capacitor will have a low initial reading that rises as the capacitor charges. If this doesn't work, I'll unplug one of the wires and try again. It may be shorted if the reading remains low. It will typically only indicate a high reading if there is no capacitance.
