Checking fuses is smart, and any wiring that has been modified, but the fuses are designed to specifically prevent any electrical short that could cause a fire, including if there was water ingress. Any water that shorted out a wire would blow the fuse and it would protect itself -- that's the whole idea.


It's not a bad idea to be aware, but I don't think you need to be paranoid about it happening. I used to carry a small fire extinguisher in my old 1985 MR2 after I swapped a supercharged engine into it and had had to splice the entire wiring harness together. They make small ones to keep in your car and you could do the same thing if you were worried. I've never worried about vehicle fires in any car other than my old Death Rocket as I used to call it.
