I have a 1997 V6 rodeo that was running great until one day the ECM fuse under the hood randomly blew causing the truck to die. So I changed the fuse and we were off on the road again, easy fix right? Now ever since the first fuse blew out, every replacement fuse keeps blowing out about 15-20 minutes after changing it. So I'm thinking there is a short somewhere and I was wondering if anyone had any ideas on where to start. Any ideas are appreciated and thanks in advance.

 

Not sure about the ecm fuse but my "main" fuse kept blowing fuse after fuse and it was my alternator..
