megger testing a hvac compressor motor winding best method, also megger testing the power wires as well, a megger ohm meter can output upto 1000 volts DC thus be able to measure resistance in the millions of ohms range, in HVAC if the wire or load measures 50 to100 Megs to ground its caution ⚠️ if measures 0 to 50 Megs its bad and is considered good if measures above 100 Megs
