An alternator will ground out when the normally insulated line that charges the battery( after going through the regulator system) makes contact with the alternator shell. This sends any voltage to the surrounding case and to any surrounding metal thusly grounding the voltage out. This can occur due to vibration or excessive moisture to the casing.
