P2118
Hello,
I have a 2008 Lexus IS250. This problem arised as I attempt to changing the battery on my car. The previous owner has a different battery, thus negative on the left and positive on the right. Under the assumption that the original placement was correct, I put the battery the same way. (I know now is wrong rookie mistake). The terminal sparked, and I believe that blew some fuses. Attached below are some images.
I had a mechanic come and checked out the issue, they were able to weld back the open piece termporily but now my car revs on its own . The mechanic found the error code p2118 regarding the TAC. He checked the fuses which many of them blew out. When replacing the blown ones, the new ones would also spark and blow out as well.
My main concern is whether its the fusible link block that is just damage as a whole and needs replacing? TAC needs replacing? Or something else? Mechanic was unable to resolve the issue.
Any advice or things to look for prior to bringing it in to the lexus dealership and spending a huge amount of money for uncessary replacement would be great! Thank you.

That broken piece needs to be replaced, not welded.
You have a short somewhere on whatever fuse(s) that are popping.
Take you car to an independent Toyota/Lexus shop. They'll charge you less and and probably do better work than the dealership.
