Use the 146-4080 Digital Multimeter (RS-232) or the equivalent for making resistance measurements. For instructions on the use of the 146-4080 Digital Multimeter (RS-232), see Operator's Manual, NEHS0678. The 7X-1710 Multimeter Probe is used to make measurements at connectors. The halves of the connector do not need to be disconnected. The probe is pushed into the wire entry side of the connector alongside the wire. The 7X-6370 Adapter Cable is a 3 pin DT connector breakout cable that is used to make measurements in the circuits of the sensors. The 4C-4071 Contact Removal Tool (4-6 Gauge), the 4C-4072 Contact Removal Tool (8-10 Gauge), the 4C-4073 Connector Removal Tool and the 4C-4074 Contact Removal Tool (16-18 Gauge) are wire removal tools for the CE connectors. The 4C-4075 Crimp Tool is used for 4 AWG through 10 AWG pins (sockets) that are used on CE connectors.
Note: The use of continuity testers, or voltage testers are not recommended for use on present day Caterpillar electrical circuits. The continuity testers and the voltage testers may be used in harness tests. The harness tests include the 8T-0500 Continuity Tester and the 5P-7277 Voltage Tester .
