I bought a Renault Twingo a couple of weeks ago. Recently, it has had a battery warning light paired with a stop light coming on about 30 secs after starting up the car.
I have checked the voltage of the battery (it's around 12V when engine is off and 14V when it is on (which I believe is the right values)) and the car seems to be driving absolutely fine.
I'm not too sure why this light is coming on as I don't think that it can be a problem with the alternator if the battery is ok.
Does anyone have any suggestions as to what I should do?
