Can a loose positive battery cable prevent the alternator from charging the batter and can it cause a battery drain while the engine is not running?
Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.

(not keep up to the demand/not charge at all)
