For instructions on servicing Sure Seal connectors, see Special Instruction, SMHS7531. For instructions on servicing Deutsch DT connectors, see Special Instruction, SEHS7734.
Use the digital multimeter for making continuity checks or for measuring voltage. The 7x-1710 Multimeter Probe is used to measure the voltage without disconnecting the connector. The probe cables are pushed into the back of the connector along the wire. The 8T-8726 Adapter Cable has a breakout of three pins. The adapter cable is used for measurements in the sensor circuits.
Note: For Cat® electrical circuits: except for harness tests, use continuity tester 8T-0500 Continuity Tester, or voltage tester 5P-7277 Voltage Tester.
