  • The battery light comes on when you turn on the car and stays lit while driving. This light should only stay lit if your engine has not been turned off in over 10 minutes, so if it remains lit while going. Then this could indicate an issue with your alternator system or other components related to charging power for electronic devices within the vehicle, such as radios and GPS systems.
  • You hear clicking noises from under the hood when starting up your vehicle (this could also indicate problems with other components).

Engine Warning Light:

If you’ve noticed the engine warning light on your dashboard, there’s a good chance that it is related to the alternator. This light indicates that your car’s battery isn’t being charged and, therefore, won’t be able to provide enough power for all the other electrical components in your vehicle. Having an alternator failure can lead to a dead battery and ultimately cause severe problems with your Holden Commodore—so it’s essential to address this issue before things get worse!

Start testing your vehicle’s electrical systems by turning off all unnecessary accessories such as air conditioning and headlights. Then, drive the car under normal operating conditions until it reaches operating temperature. After driving for 20 minutes at highway speeds, stop the vehicle and check whether its engine has maintained a steady idle speed with no fluctuation in RPMs (revolutions per minute).

Strange Noises:

Several things: can cause irregular noises from the alternator.

  • any loose belts or pulleys
  • worn bearings in the alternator
  • the dirty or broken fan belt

If you’re unsure what is causing these sounds, it’s best to have your mechanic check them out. One way they can do this is by placing an oscilloscope on the connections between your battery and the alternator output terminal. It will show any problems with small electrical parts like brushes and commutators. If there are issues with these components—such as excessive wear or damage—they may need to be replaced before driving off in your new-to-you Holden Commodore again!
