Help! Alternator/Voltage Regulator >:[

it was 12.3 with the car running with lights, radio, electric fan on, sometimes it even dropped to 12.14 (especially with the electric fan running). If I shut everything off though (with car running) then the battery voltage goes up to around 12.7. If the alternator is putting out 13.8 volts directly from the post then I would assume this is a connection problem?
