Believe it or not, I actually trained as an Auto electrician when i first left school.
Mainly on Plant & Commercial stuff with a few cars / motorbikes thrown in for good measure but decided I liked working on mains stuff better than DC so changed over.
Done bits & pieces of Auto over the years but like you not regularly enough to be really up on things, totally agree with having to be a contortionist. It's definitely a youngster's game nowadays.
