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.

225-8266 Ammeter Tool Gp | |
The 225-8266 Ammeter Tool Gp is a portable, self-contained instrument that allows electrical current measurements to be made without breaking the circuit or without disturbing the insulation of a conductor. A digital display is on the ammeter for displaying current measurements in a range from 1 A to 1200 A. A 6V-6014 Cable can be connected between the ammeter and a digital multimeter 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
Note: Refer to the ammeter's User's 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 | |
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
- Voltage
The 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 multimeter's Operator's Manual for complete information that is related to the use of the multimeter. This manual is packaged with the unit.
