No-Load Check

NOTE: Use fully charged battery.

Check for DTC.
- N32A: See DTC CHECK .
- J24B: See DTC CHECK .
If there is any DTC, perform trouble shooting for applicable DTC and then clear DTC.

Trouble shooting:
- N32A: See DTC TABLE .
- J24B: See DTC TABLE .
DTC clearance:
- N32A: See DTC CLEARANCE .
- J24B: See DTC CLEARANCE .
Turn off all electrical loads (5).

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, bushes and regulator. See GENERATOR INSPECTION .
