In an AC compressor, the four windings typically refer to the main components of the compressor's motor, which include the start winding, run winding, common winding, and a potential relay or capacitor winding. The start winding is energized briefly to help the motor start, while the run winding maintains the motor's operation. In some designs, a capacitor may be used to improve efficiency and starting torque. These windings work together to ensure the compressor operates effectively and efficiently.

With an ohm-meter. Check for continuity in the RUN and START windings, and also from the terminals to compressor case for shorting. There should be continuity in the windings and no continuity from windings to compressor case.

Defective pressure switch not cutting out on hi-head pressure The compressor depends on the suction line for coolong the motor, if its low on freon then the suction line will not be cool enough to cool motor windings.
In a hermetic compressor, oil is typically contained within the compressor unit and does not directly touch the windings. Instead, oil circulates with the refrigerant to lubricate moving parts, while the windings are insulated to prevent electrical contact. However, any leakage or malfunction could potentially lead to oil reaching the windings, which could cause insulation breakdown and failure. Proper maintenance helps mitigate these risks.
Usually you check mega-ohms by reading the resistance between compressor shell and the windings. There should be a large amount of resistance which means the windings are not shorted to the compressor case or shell. Use a DVM (digital volt ohm meter) to check the resistance.
