257-9140 Digital Multimeter Gp 1 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

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
