Hi all, i recently bought a mk2 focus, i had to replace the alternator a few mo ths ago due to a dodgy charge connection inside. About a month later my battery light came on while i was stuck in traffic so i stopped the car straight away and checked the battery etc over and everything is fine and charging as it should. I have plugged in a code reader and its not showing any codes, ive checked all the fuses i can find and all are good. I dont really want to pay an auto electrician of ford garage if i can help it.
