Regulator appears to be shot, maybe the alternator. at that RPMs it should read 14.1-14.3 volts. 11.6 your battery is dead or damaged.
Remove the alt, then the regulator and inspect it, if good, put back carefully and have it bench tested, bring your pulley halves with you so they can put a belt on it.
Have battery tested too
