A number 7 fuse short circuit

[ttanaka504@xxxx]

Dear list,

Hello, list. I am having the electrical problem.
First I notice that my D had a hard staring engine problem.
After 2 months later I drove my D, the engine never start again.
Therefor I was checking the reason...

I found out the a number 7 fuse was burned. 
SO I changed new 20A fuse, but after I started the engine,
the fuse die immediately. 
The fuse take care of lambo relay and ECU, fuel pump, etc.,
I thought fuel pump area is doing something bad.
Two line connector terminals were became blue like corrupt.
I cut and rewired them.
Also I never changed relays, so I simply changed all relays.

Even I worked the car with poor skill, my d still dont start the engine.

It start but 1 or 2 second later engine is stopped because
#7 fuse is burned. I can use tester, but I dont know where
I should look first. 

Can you please any help? 

Also can anyone please tell me how to change + and - battery wires 
because I am thinking to replace with high grade audio(22sq) 
wires. And New battery wire should reduce electrical loss. 

Thank you very much for all help.
