The unfortunate thing is diagnostics DOES TAKE TIME. You need to set aside the time to be accurate.
Something for sure is draining the battery and methodical diagnosis is the only way to get it figured out. IF there were an open in the alternator to battery circuit, the new alternator would be damaged.
Pull the interior light and radio fuses, disconnect the negative battery and put a test light or volt meter in series with the cable and battery terminal. I expect the light will be lit or the voltage to be above .2 volts draw.... Disconnect the battery, remove one component, connect the battery test setup, and see if voltage drops or light goes out..... when it does, you have the offending system, so investigate that.
Be sure that you can garantee good ground between battery and everything....especially the engine.
