I have a 93 240, was driving it home at night and it died. I had the battery replaced last week. Took it to autozone and they said the alternator was bad. So I changed it was taking it around the block and it died again like it wasn't keeping charge. Got it back up to autozone was still reading the alternator was bad. The guys there suggested that there could be a fuse somewhere that is blown and not allowing the alternator keeping the battery charged. My question is there a fuse. If not what could be causing this?
