Driving to work this morning my battery warning light came on. Is the most likely cause a broken alternator, or are other things equally likely (wiring / fan belt / diodes)?
Also, recently my car has been screeching as I accelerate from low revs, and every so often I get a rattling sound.
The fiesta is getting old now (140,000 miles - 1993 fiesta). If it is the alternator is it worth replacing? How much is this problem likely to cost me?
Cheers, David
