2. Test for voltage between pin #1 to pin #3 on the wire harness connector. If voltage is detected, jump pin #1 to pin #3 using a jumper wire.
Compressor clutch should engage.
3. Check for voltage between pin #1 and pin #2. If no voltage is detected, check fuse and ground circuit.
4. If compressor clutch engages, test for continuity from terminal pin #1 to pin #3 of the switch lead connector. Continuity should be detected. If not,
replace the Fin-sensing Cycling Clutch Switch.
