Its not your engine. Its the fan running to cool the engine down. They all do it and nothing is wrong with your car.

Why does the fan keep running on a 1983 caprice classic when engine is off?

If the fan keeps running it's because it is electric and wired through a temperature switch not the ignition. Electric Fan running is independent of engine running. When the temperature is high enough to start the fan, it goes on. when the temp drops the fan goes off. Temp does not drop right away when the car is turned off. It can actually rise several degrees when the engine is turned off. The fan running after engine shut off is actually a good thing that may prevent radiator overflow

What would make a car discharge besides the battery and alternator?

All of a vehicle's electicity using devices drain/discharge the battery, but during the time the engine is running, the alternaror is supposed to keep the battery recharged. If the engine IS running, but the alternator is NOT providing enough current to recharge the battery then ALL of the electricity using devices discharge the battery. Some of the "onboard" computers draw some slight amount of power even when the ignition switch is off, but they do not use enough power by themselves to significantly discharge the vehicle battery. Any electricity using device which SHOULD be turned off when the ignition is off, BUT... which due to some fault [such as a "stuck" relay for example] that keeps that device still turned on when the engine is not running and the key is off will also discharge the battery. Or, just leaving the ignition switch on without the engine running, or the headlights or parking lights on, or sound equipment left on will contribute to discharge of a vehicle's battery.
