Voltage Regulator and low output from Alternator

So I pulled the alternator off and I get open on the each ground to field and about 22.4-22.9 ohms of resistance from field to field. I double checked the voltage out again and it is still floating around 11.7-11.9. I am ground on the thermostat body bolt. I checked across the lugs of the battery and positive to the bolt and the voltage was within a couple of point .2 to .3 variance. I feel confident that I am using a good ground.
