If I am not mistaken, the voltage regulator is built in the alternator; you need to replace that alternator completely, the undercharging will also damage cells in your battery.

Your output at the battery while running should be over 13.5V-14V with the lights off, and just over 13V with everything (lights etc.) turned on... 11.3V is a dead alternator and will kill the battery, since its output isn't enough to both run the cars electrical accessories and charge the battery... The alternator runs the entire electrical system, and the excess voltage charges the battery and keeps it charged.
