i have a 2.0 fiesta si, ive had its been up and running fine since xmas, the problem is the past couple of days the battery keeps going flat? theres no battery light on the dash to suggest the alternater so i brought a new battery. thought problem was solved, but it isnt? i get the airbag light come on when the battery gets low? i take it this is the alternator?

get a volt meter across the battery while its running and see what its charging at

ideally want around 13.5 volts anything lower than id say 11.5 then altrnator isnt charging and time for a new one

Cowboi

like i told ya paul

have u got a meter?
if not pop round i'll check it out for ya.

come now if u like.

but if u charge ur battery u'll get an hour or 2 of driving out of it.

just dont put ur lights or anything on.

thats what i had to do when my alternator died.

Altratz

i recently had a problem like this on my saph cos found out it was the battery warning light bulb in the dash!. if it is the same thing it explains why your not getting the light come on!.the bulb is part of the circuit and without this the battery wont charge but the car will run off the power of the alternator just a suggestion as this fixed my problem and only cost me 25p regards Alex.

Nick.

13.5 volts is still to too low in my opinion for an alternator to be charging properly.. ideally I would want to be seeing around 13.9-14.5 volts

But low charging (if yours is charging at all?) could just be down to something as simple as a bad earth or a slack alternator belt so I would check those first

sorted i think it was the power cable from the starter moter to the alternator worked a little loose so not gettinga full charge. cheers guys
