Clutch line/fire problems

[Shift-240]

Alright before I start I did search not just zilvia the web. Here goes awhile ago I relocated battery with no problems, then one day it just wouldn't start. Well I tried to figure it out on my own and just came to a halt everytime, So I had a mechanic I know come and look at the car. He tinkered for about 10 mins or so the poof my tranny harness went up in flames. That was a surprise but a bigger one was the mechanic said there was no visible reason for this, so I changed the harness and my clutch line since it was caught in the fire. Now just about a week ago I was headed to get my tat finished and my friend noticed smoke coming from under my car, So I pull over and check nothing so I just went home. Ok so yesterday I go out buy a new alternator and this morning decide to put it in look down and my clutch line is cooked. A brand new clutch line crispy I make a few phone calls check theres nothing around my clutch line that would catch it on fire...What I am asking is there any reason for a clutch line just catching fire?
If you are just going to flame me please dont post.
