Compressor Magnetic Clutch Circuit

Circuit Description
The air conditioner control assembly outputs the magnetic clutch ON signal from terminal MGC to the ECM. When the ECM receives this signal, it sands a signal from terminal ACMG and switches the air conditioner magnetic clutch relay on, thus turning the air conditioner compressor magnetic clutch on.
The air conditioner control assembly also monitors at terminal NC IN whether or not power is being supplied to the magnetic clutch.
