I have an 89 Nissan truck. Recently while my son was driving it one
of the fuse links attached to the battery blwe. No lights, guages
etc. My local mechanic couldn't find a problem and replaced the link
with a 15 amp fuse. It still blew. I loosened the alternator belt
and was barely able to get it to turn, so we replaced it. Now the
truck idles rough and cuts out during acceleration as well as blows
the fuse. I'm out of ideas. Help?!?
