Most of the tests for the electrical system can be done on the engine. First, check that the insulation for the wiring is in good condition. Ensure that the wire connections and cable connections are clean and tight. Check that the battery is fully charged. If the on-engine test shows that a component is not functioning properly, remove the component from the engine for more testing.Refer to Testing and Adjusting Electrical Components, REG00636 for complete specifications and test procedures for the components of the starting circuit and the charging circuit.4C-4911 Battery Load Tester
Illustration 1 g00283565
4C-4911 Battery Load Tester
The 4C-4911 Battery Load Tester is a portable unit in a metal case. The 4C-4911 Battery Load Tester can be used under field conditions and under high temperatures. The tester can be used to load test all 6, 8, and 12 V batteries. This tester has two heavy-duty load cables that can easily be fastened to the battery terminals. A load adjustment knob is located on the top of the tester. The load adjustment knob permits the current that is being drawn from the battery to be adjusted to a maximum of 1000 A. The tester is cooled by an internal fan that is automatically activated when a load is applied.The tester has two built-in Liquid Crystal Displays (LCD). During testing, one LCD displays the battery voltage at the battery. This measurement is taken through tracer wires that are buried inside the load cables. The other LCD accurately displays the current that is being drawn from the battery which is being tested.Note: Refer to Operating Manual, SEHS9249 for more complete information for the use of the 4C-4911 Battery Load Tester.271-8590 Starting/Charging Analyzer Gp
Illustration 2 g01789234 271-8590 Starting/Charging Analyzer GpThe 271-8590 Starting/Charging Analyzer Gp is a portable, hand-held tool. This tool is used to test the condition of all 6, 8, and 12 V batteries. The tool can also be used to test 6, 8, 12 V and 24 V battery packs. The tester can also be used to test the starting and the charging system. The analyzer has a multifunction input for use with multimeter probes that are an optional purchase. The analyzer also has a print function that is used with a printer that is an optional purchase.Note: Refer to Operating Manual, NEHS0973 for more complete information for the use of the 271-8590 Starting/Charging Analyzer Gp.225-8266 Ammeter Tool Gp
Illustration 3 g01012117
225-8266 Ammeter Tool Gp
The 225-8266 Ammeter Tool Gp is a portable, self-contained instrument. The tool allows electrical current measurements to be made without breaking the circuit or without disturbing the insulation of a conductor. A digital display is located on the ammeter for displaying current measurements in a range from 1 to 1200 A. A 6V-6014 Cable can be connected between the ammeter and a digital multimeter in order to measure a current of less than 1 A.A lever is used to open a jaw on the meter that clamps on any conductor up to 23 mm (0.90 inch) in diameter. The jaw of the meter closes around the conductor for the current measurement. A dial is used to set the appropriate range for the amperage reading. A "HOLD" button on the meter allows the latest reading to be sustained on the display. If a measurement is taken in a limited access area, the meter will retain the measurement data until the user is finished. Batteries are used to power the ammeter.Note: Refer to the User Guide for complete information that is related to the use of the ammeter. This guide is packaged with the unit.146-4080 Digital Multimeter Gp
Illustration 4 g01015638
146-4080 Digital Multimeter Gp
The 146-4080 Digital Multimeter Gp is a portable instrument that has a digital display. This multimeter is case hardened with a rubber protector cover that provides extra protection against damage in field applications. The 146-4080 Digital Multimeter Gp can be used to perform the following measurements:
Amperage
Capacitance
Frequency
Pulse Width Modulation (PWM)
Resistance
Temperature
VoltageThe multimeter has an instant ohms indicator that permits the checking of continuity for fast circuit inspection. Temperature measurements can be taken by using the adapter for type K thermocouples. An RS-232 interface adaptor can be used to interface with other electronic tools and displays.Note: Refer to Operator Manual for complete information that is related to the use of the multimeter. The operator manual is packaged with the unit.
