4.6.2 Solenoid Coil Harness
Figure 4-30 Solenoid Coil Harness
4.6.2.1 Solenoid Coil Harness Removal and Installation
For details, refer to Section 4.6.4 Solenoid and Coil Removal and Installation on page 75.
4.6.3 Solenoid Verification
• • • CAUTION • • •
When actuator coils are removed from the solenoids, they must be replaced in the same location. Incorrect installation can result in
damage to compressor components.
4.6.3.1 Resistance Measurement of Cooling Solenoid Coils
1. Isolate compressor power.
2. Remove the Service Side Cover. Refer to Section 4.1.3.1 Service Side Cover Removal and Installation on
3. Disconnect the Compressor-Cooling Solenoid Coil Connector (J16) from the Backplane.
4. Set the multimeter for resistance measurement. Refer to Table 4-10 Solenoid Coil Resistance Ranges on
page 74 to find the expected resistance for the left and right Compressor-Cooling Coils.
5. To measure the resistance across the left Compressor-Cooling Solenoid Coil, place the meter probes at
Pins 1 and 3 of the cable connector. Refer to Figure 4-32 Compressor Cooling Solenoid Coil Cable
Connector on page 74.
6. To measure the resistance across the right Compressor-Cooling Coil, place the meter probes at Pins 5
and 6 of the cable connector. Refer to Figure 4-32 Compressor Cooling Solenoid Coil Cable Connector
on page 74.
