If you look at the question "what's wrong with my discovery" the same could apply to your car.
Or the previous answer could be correct about the alternator. This would be easy to check yourself. Start the car whatever way you can bump start or jump leads. Now when engine is running turn lights on full now watching the headlight's rev the car up if the lights get brighter then the alternator is charging.
You say there is a continual clicking well this could be starter or at the worst the teeth on either the starter ring gear or even the flywheel are damaged or even broken.
