For instructions on servicing Sure Seal connectors, see Special Instruction, SMHS7531. For instructions on servicing the Deutsch "DT" Type connectors, see Special Instruction, SEHS9615.
Use the digital multimeter for making continuity checks or for measuring voltage. For instructions about the use of the 6V-7070 Digital Multimeter, see Special Instruction, SEHS7734. The 7X-1710 Multimeter Cable is used for measuring the voltage at the connectors without needing to disconnect the connectors. The probe cables are pushed into the back of the connector along the wire. The 8T-8726 Adapter Cable has a 3 pin breakout. The adapter cable is used for measurements in the sensor circuits.
Note: Except for harness tests, using continuity testers such as the 8T-0500 Continuity Tester or voltage testers such as the 5P-7277 Voltage Tester is not recommended for today's AVSpare electrical circuits.
