What problems can be caused by a faulty Alternator?
Car electrics failing / no power
When turning on the ignition there's no power at all in the car, the dashboard isn't lighting up and the car won't turn over.
Battery does not hold charge
The battery does not hold charge for very long, even if it is charged up with a battery charger after a while of running the car the electrics fail again. It doesn't seem to be re-charging itself as the car is driving.
Engine doesn't start up and/or cuts out when running
The engine doesn't start up very easily and will often not start at all. When it is running it can cut out completely without warning.
Battery warning light shows on dashboard
A warning light that looks like the one pictured on this page has appeared on the dashboard and doesn't go out after the car has been running for a while.
