What numbers are you expecting? 14 volts running, and 12volts on the battery when your car is off is acceptable. The rest voltage in your battery deteriorates as the battery ages. 12 volts indicates an aging BUT still good battery, and in no way indicates a bad regulator. If while runing under load, you have high 13's to low 14's, your alternator and regulator are o.k. as far as the volts are concerned.
