Undue mechanically transmitted noise or vibration
• Noise or vibration transmitted down the shaft
– suspect a loose rotor. Grasp an blade and rock the rotor to check if there is
any relative movement between the rotor and the alternator shaft. If play is felt,
remove hub parts and re-build, fitting a new hub centre.
• Correct fit of nose cone
– check that the nose cone is not catching on the alternator housing.
• Blade damage
– check that the blades are not damaged or chipped. This may put the rotor out of
balance. Replace blades as necessary.
• Tail bolts
– check tail bolts are tight.
• Noises from the alternator
– rotate the blades slowly and listen at the alternator housing. Grating or
scraping noises indicate a fault within the alternator. Refer to your dealer or Eclectic
Energy Limited.
