The Valeo SG10 and SG12 generators are electrically similar to earlier models. The generators feature the following major components:

  • The delta stator
  • The rectifier bridge
  • The rotor with slip rings and brushes
  • A conventional pulley
  • Dual internal fans
  • The regulator

The pulley and the fan cool the slip ring and the frame.

The generators feature permanently lubricated bearings. Service should only include tightening of mount components. Otherwise, replace the generator as a complete unit.
