Oh.. devil's advocate.. I *like* this game..

The cap is wired in parallel with the alternator and the battery. describe a situation where the cap could become completely discharged without the battery and alternator being affected. At most I'd suspect you'd see some voltage drop in the wiring, but nothing close to 0v..

I'm thinking that the cap would actually help reduce the heavy spikes that the alternator might see during heavy base.. isn't the reason for installing a cap is to help eliminate the dimming light effect?..

FYI, it is impossible for a capacitor to "become completely dischsrged" unless the battery is also "completely dischsrged" and the alternator is producing zero volts. A capacitor will maintain whatever system voltage happens to be.

Exactly.. under normal operating conditions the battery, alternator, and cap should all be around the same voltage.. excluding voltage drop in the wiring.
