There is no trick or bypass for the charging system.
The generator is what maintains the battery. It has the regulator inside which keeps the alternator from overcharging.
If you have a voltmeter, make sure you have power to the orange wire at the alternator connector. It is fused controlled.
Beyond that, I would remove the alternator and take it to a parts store and have them check the part. It is a free service. That will tell you if it is the alternator or the PCM which controls turning on and off the regulator.
