Peter, good addition. Forum members can also reference page 5-14 of the FSM on stored DTC resetting by shorting the DLC.
For those not familiar with capacitors (condenser is an old term), most dry capacitors are wound layers of foil and paper insulation which store a charge.
Most of us oldsters are aware of capacitors used for a points type ignition;
typically 0.22 microfarad units.
When points open, voltage charges the capacitor, to save burning the points during contact separation. When points close, the capacitor discharges into the coil to accelerate coil energization. If the capacitor is not to spec, points will pit on one side and build material on the other.
When I operated an electric motor rewind shop, we had meters for measuring capacitors, but for starting capacitors, we'd just energize, through a resistor (avoid a dead short), remove the lead, then short the terminals with a screw driver. Some sparks and a sharp "snap" and it was considered good. That could be done on some running capacitors, also.
Large capacitor banks are used at power stations to offset VARS from resistance loads.
For their use in electronic circuits, Popgun or Max or others with electronic backgrounds would answer better than I...other than I am aware that their storage capacity allows memory of station presets in modern automotive radios.
