Wire on solinoid fried. Believed it arced from starter power

[Driftagain]

My question is how do I fix this problem. I was finishing a swap had it started but the power to starter was loose. The next day went to wrap it all up to drive it but wire to solinoid was blown off. I reconected the wire and now it will not start. I'm not sure what to try next after some tests I found the eng.fuse blows when tring to start the car weather the starter is powered or not. So do I have to try replacing the entire wire coming from solinoid or did something else happen to the egnition?

I replaced the antitheft relay now the fuse stopped blowing. The starter doesn't engage completing, I'm guessing the wire has a slight brake or the battery is not throwing out enough amps anymore sence it's in the trunk and the power cable is much longer.
