Narrative:
East of la veta pass at 11;500 a discharge on ammeter was noted. Cross checked ammeter with graphic engine monitor and determined no output from alternator. Master switch recycled; all circuit breakers checked; alternator still offline. At this time I was in contact with denver center on a discretionary code (flight following). Decision made to divert to publication for maintenance. Decision also made to lower the landing gear to avoid having to lower manually. Gear lowered and depleted remaining power. All avionics went offline including comm/gps/transponder. Separate 'stratus' ads-B used to show navigation and traffic; plus current conditions at publication on an ipad. Entered publication traffic pattern on a downwind leg; observed green light from tower and entered left base for landing while watching for light gun signals and traffic. Taxied to FBO while observing flashing green tower light. Tower indicated they had been informed by denver center of our landing at publication.
