Typically this only blows the large ALT fuse this is normally 100 AMP or 120 amp's. Have you located this fuse?
No, not sure where that is, I have little car repair experience.
There is a fusible link box attached to the cables that go to the battery. Click the link below for a better illustration. Inside this box you will find fusible links. As I recall that 120 amp ALT fuse has to be replaced as part of this fusible link box. As a test you can put a jumper wire across the burned-out link to see what else does not work. The 120 amp fuse is a main power input to most the subsystems. The good news is typically does not damage any control computer's.
So basically I have to unbolt the positive battery lead and the covered positive wire lead and replace the entire grey box?
