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. Service personnel can use the 7X-1710 Probe Cable Group to measure the voltage of a circuit without breaking the connection. 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 Caterpillar electrical circuits.
The off-board service tool connector provides access to VIMS by way of the RS-232 data link. This connector is a military type connector. The service connector of the Electronic Control Analyzer Programmer provides access to the electronic engine control by way of the CAT data link. This connector is a HD type connector. These service connectors are usually located both in the cab and at ground level. The service connector for the off-highway trucks is located on the “left front bumper area”. The service connector for the large hydraulic excavators and large wheel loaders are located near the ground level access ladder. Later hydraulic excavators will not have a service connector at this location. Use the machine Electrical System Schematic in order to locate the position of the service connector.
