Help! Alternator/Voltage Regulator >:[

Alright, here's my current battle. I just recently got a 100 amp alternator because I have more electrically demanding things in my car. The alternator is putting out roughly 13.8 volts...the battery however is putting out 12.3 with lights/radio on. I just replaced the battery with no success in fixing my problem...which brings me to my next thing...could it be the voltage regulator? Are regulators different when going from a 65 amp to a 100 amp alternator?

Thanks!
Craig
