Compressor Magnetic Clutch Circuit

Compressor Circuit

DESCRIPTION
The A/C amplifier outputs the magnetic clutch ON signal from terminal ACT to the ECM. When the ECM receives this signal, it sends a signal from terminal MGC and switches the A/C magnetic clutch relay ON, thus turning on the A/C magnetic clutch.
