| 1. | Be sure the battery is sufficiently charged. |
| 2. | Hook up the following equipment:
|
| 3. | Start the engine. Hold the engine at 3,000 rpm (min-1) with no load shift lever in Neutral, until the radiator fan comes on then let it idle. |
| 4. | Raise the engine speed to 2,000 rpm (min-1) and hold it there. |
| 5. | Turn the headlights (high beam) on, and measure voltage at the alternator terminal. Is the voltage between 13.9 and 15.1 V? YES - Go to 6. |
| 6. | Read the amperage at 13.5 V. NOTE: Adjust the voltage by turning the blower motor, rear window defogger, brake lights and etc. ON. Is the amperage 60 A or more? YES - The charging system is OK. Go to alternator control circuit troubleshooting.n |
