I have removed and checked the starter and the alternator. Both are supposed to be good still. I also removed the battery and they said it was low. They recharged it and I replaced it. It immediately went low. The guy checked and said the alternator was not working, although it was checked and is OK. He then said something about a fuse link. I don't know where that is. Can you help? This is a 2001 hyundai sonata
