The alternator should only put out like 13.5 to 14.5 volts so the regulator is probably bad. Nowadays the regulator is built into the alternator, on old cars it was sometimes seperate. Only other thing it could be is wire that feeds alternator like a sample voltage could be bad but it is a long shot.
