The one I'm referring to looks like a piece of charcoal. The only thing you could get out if it is a paper weight. IIRC, Errin originally posted the pic a long time ago.

It should be rated for a little less current than the gauge of wire can support. 4 gauge is typically good for somewhere around 130a. It should be fused at the battery with a fuse value of approximately 125a...

At the amplifier end, the 80a fuse is to protect the amp from similar scenarios to what I outlined above. If something goes wrong internally in the amp, the fuse will blow before it can cause a catastrophic end...

The fuses still go in the same places mentioned earlier in the thread. See above...

This one?

If so, the one I got a hold of was a different board revision, but had nearly the same amount of damage:

Here is my one that I fixed and am running right now:

Pretty much the same damage, every one of the power supply fets had violently exploded or burned. Hot enough to melt the aluminum clamp bars
