No-Load Check
NOTE:
Use fully charged battery.
- Check for DTC, see DTC CHECK
.
If there is any DTC, perform trouble shooting for applicable DTC and then clear DTC.
- Trouble shooting: DTC TABLE
- DTC clearance: DTC CLEARANCE
- Turn off all electrical loads (5).
- Connect voltmeter (3) and ammeter (2) as shown in figure.
- Start engine and warm it up to normal operating temperature.
- Run engine around 2, 000 rpm and read meters.
- If voltage is higher than standard value, check ground circuit of brushes, see GENERATOR INSPECTION .
If brushes are not grounded, replace IC regulator.
- If voltage is lower than standard value, inspect rotor, stator, rectifier, bushings and regulator, see GENERATOR INSPECTION .
