HALF WAVE RECTIFIER- with &without filters,important parameters,etc..

[@waterfuel]

Question? - I have circuit diagram from 2005-2008. It has DC to AC Inverter of 120v AC output secondary of (2) leads, hooked with diode on each secondary line , that is reversed polarity .( Both different) one way , then other way. My test meter reads both on AC and DC . How do I get proper reading on this? One cathode faces outward, other diode cathode faces secondary Is this still AC output? Is this half wave DC or still AC? How to tell if negative or positive DC out?
