Signs your alternator is failing –
• If you notice a change in electrical supply, for example dim lights that get brighter when your engine revs increase and the decrease again as you slow down this could be a sign your alternator is failing and not generating enough power to keep up with the electrical needs of your vehicle.

• Flat battery
• Dash warning lights
