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 .
