Melted Fuse

[newsh]

What do you reckon this is all about fellas?

ISV fuse it seems.

poor contact at fuse connector. This made the amps to go high and melt the fuse.
Maibe with good cleanup and contact enhancer you will be able to fix that.

Alwyas frustrates me when fuses do this instead of just blowing, seems to override the safety aspect of the fuse

fuel pump fuse.

Drawing too much current possibly. Check the earths

Any electrical connection that is not tight will create heat as the currant passes through it and in this case the heat has melted the fuse and fuse box base, think your self lucky it could have went on fire, dose look like a replacement fuse box is required, make sure all of the remaining fuses have a good tight connection, simple test would be to run the car for 30 minuets or so and remove the fuse box lid and do a touch test with your finger, no fuse should run that hot that you can not touch it.

As above, poor connection making resistance resulting in heat.

Fuel pump fuse! I didn't read the fuse box lid properly..

Time to relay the pump under the back seat I reckon.

Raining here at home but getting colder.

But who can this be? From Scotland??

I'm just a poor boy and my story's sad to tell, well just go an 1991 S2 to add to my collection of Audi's and I think I am living the dream.

#5 & 6 spot on, in my opinion.
Corrosion (prob on the fuse, as opposed to the carrier- which is prob brass) is almost certainly the issue here.
If it was caused by overcurrent, then I can't see the heat being transferred to only one side of the carrier in the fusebox.
Fire? I really don't think that the fusebox is gonna be made from a normally flammable material. (Again- IMO)

Rain is off now, done a few jobs......Porsche alarm fault and a 20 years young Vectra with goosed battery. In a different car park now!!
