Really Sc***ed?
Started removing excess loom from the MX5. Started with the cabling for the rear lights and work my way backwards to engine as it was one of the
easiest and small pieces of the loom.
I am amazed at the thinness of the wires. Anyway, as i hope to be running LEDs i don't mind that much.
Next step was the dashboard loom. Removed all the unnecessary wires eg. electric windows, stereo, interior lights, aircon.
Kept the one for the heater, handbrake, cluster etc..
F**k, One wire is badly melted.  worst, stuck with the rest cause of the plastic melting. Pealed it gently and traced it back on the fuse box, but
as said, it has melted on the rest of the loom. My worry is that the fuse wasn't blown, but started melting.
What do i Do? Scrap it and get another one just in case? I would be gutted to rip another dashboard out, engine bay loom cause of that.
Inspect all the wiring for damage? About 800 gazillion wires?
F***N Japanese S**t
Advice needed

could you not just replace the wire, it was probably because the fuse in the suse box was too big for that wire so the excess current didn't
trip the fuse. probably the numpty that replaced the fuse didn't have a clue.

Well said. Just managed to get the fuse diagram. It was supposed to be fitted with a 15A fuse and had a 10A one. Still though, What do i do about the
rest of the wiring. Shouldn't i worry about short circuits cause of the melted plastic?
Do i just hope it didn't do any more damage?

If it had a 10A fuse instead of a 15A one, that is the opposite of what Omega said... you would expect the fuse to have blown too early, not to have
allowed the wire to melt

cut out all the damaged wires - solder new ones in - use heatshrink over soldered part - cheap job and easy to do without worry

My only problem with that is that i need to inspect all cables individually in a loom that has 50mm in diameter. Can you imagine how many cables there
are?

Jap cars tend to have some of the most reliable electric around, Italian being the worst
User error no doubt, probably went through all the spare fuses before ending up with the 10A one

yes I can - the loom in my volvo has loom as thick as my wrist!! 
as I said previoulsy, strip out all the unnecesary wires, shold be down to little finger width.

theres nothing to say the 10a fuse was in when it melted, it could have been any rating then?
I'd have a look over the rest of the wires in that location, if any of the wall on the other wires is broken or looks as though its melted
really thin i'd replace otherwise you should be fine.

Perfect planning prevents pi$$ poor performance!

My money is on the fact that after fitting a 25A instead of the 15A, someone told Mr Numpty that fitting a fuse too highly rated is not a good idea so
he fits a smaller one as that's all he had
Just my opinion...
I would be inclined to check for shorts between the suspect wire and others (especially earth) just in case there is something else amiss.

Better for the meter to find a problem than a fully charged battery !!
