A/C Compressor Clutch Break-In
After installing a new field coil-core, check for correct voltage/amperage. Cycle the A/C clutch approximately 20 times (5 seconds ON and 5 seconds OFF). For this procedure run engine at 1500 to 2000 rpm and set the system to MAX A/C mode. This procedure will seat the opposing friction surfaces and provide a higher clutch torque capability.
