Did I call you an idiot recently? You have got no clue how these investigations are conducted, do you? Of course they will inspect all the wiring they can lay their hands on. And of course it won't disrupt any traffic. If they indeed find any fault with the wiring they will either advise to replace it within a certain time, if there's something faulty with the setup or they will find out that maintanance wasn't up to scratch.
Been there, done that with previous accidents.
