  • if your fuse box melted, you need to check your entire wiring loom - it's a sign something went badly wrong...

Make sure there is no corrosion in side the positive and negative wires, there should be no bumps or warped looking rubber around them, if there is then split the rubber and clean it out further and electrical tape it back up.

Id check fuses under the steering wheel as well. Get a fuse light tester and turn ignition on and see if anything turns that light on.

If not then maybe take it to a professional to have a look at it because you might have short and thats difficult to find.
