Battery Light on, All OK

My Battery light has been on for months now, battery charges fine checked the voltage with the engine on so can't be alternator reads 14.6v with engine running.

What else can cause the light to come on. Ive got MOT next month and I'd like to sort it out. If it helps it goes dim and flickers.. sometimes but rarely it does go out with driving.

Cheers

It isn't actually a 'battery' light, it is a charging indicator light and as such usually indicates a fault with the alternator or the charging system. It may appear to be charging OK at present, but might indicate a developing fault that would require an alternator repair/replacement in the near future. The varying brightness and flickering could suggest a poor electrical contact or a loose or damaged wire.

I would start by checking that the connectors on the alternator are secure and making a good contact, and check that the battery earth straps are also secure and making a good contact (ie. not loose or rusted) where they attach to the inner wing and bonnet landing panel. Also check the power and earth lead connections to the starter motor.

I have had it before when it's an internal fault within the alternator. Although it charges ok the light stays on. When I had it the repair was to change the alternator.

14.6V is a bit high, 14.2v would be more expected so I suspect the voltage regulator on the alternator could be faulty.
