Hey everyone, wondering where the main fuse is in my 1989 Camaro Iroc-Z 5.7L. Pretty sure it blew. No power to the car but my battery is reading 13v. Thanks in advanced

 

Fuses are underneath by your left knee area.

 

There is no single "main fuse" that will kill every electrical device in the car . there are a few "fusable links" that control subgroups of components like the headlights , engine controls , and so on .

If nothing whatsoever has power then you have a bad connection at either battery terminal or at the starter (positive) or block/body ground . That or a bad (corroded clean through) battery wire would be my best guesses as to things that would kill all power in all circuits while the battery still shows voltage .

 

Fusible links near the starter motor are a point of failure.
