Fuse Box Help

What kind of vehicle are we working on?

There are two possibilities, one of which does not match with your high amperage reading.

When the ONLY problem is a loose/ broken/ corroded fuse holder clip, that bad connection will make HEAT which will blow the fuse, possibly melt insulation off the immediate wire, as well as the fuse box

But if you are REALLY getting 25 amps, that indicates a short somewhere, because there should be nothing on that circuit to draw that much.

It appears that this fuse (depending on year) feeds dome, stop, tail, and emergency flashers.

DO YOU HAVE A SHOP MANUAL, and WHAT YEAR /MODEL are we working on??
