Hi got a problem with my fiesta 2003 1.4 tdci zetec.
just happened recently and no work has been done on the car,the battery light is on all the time when the ignition is on and whilst driving.
Nothing has been left turned on.
next morning battery is as flat as a pancake (3 volts)
re-charged battery overnight and left to stand for 12 hours voltage check was 12.4 volts.
When fitted to the car and engine is running the voltage is 14.5 volts
yet the battery light is still on and the battery is flat again next morning.
Any ideas would be great
Cheers
