As a retired Aero' electrical engineer I often wonder if any car , particularly an XK8, rolls of the assembly line with all the fuses fitted the right way round. The reason I ask is that when I see any fuse the wrong way round it prompt's me to think that a problem may have occured in that particular circuit. My car was not new when I bought it, perhaps new car owners could clarify.

Very interesting thought. No way to prove it, but I'd think its most likely one would assemble with all legends facing the same way. Good catch.

I bet you're on to something. You get the Sherlock award IMO.

I almost said the "Monk" award, which was a tv show detective based on Sherlock Holmes, with a character named Monk, set in the 20th century, who was dealing with an extreme case of OCD :-)

I have done new car PDI and worked on NEW CARS at the dealer and I have never seen all the fuses installed with the marking all the same.

They are installed in a haphazard fashion.

When I read the original post in this thread, my first thought was, "What electrical engineer thinks that there is a right way or a wrong way to orient a fuse?" Then I read the second post and realized that the question did not relate to any electrical properties of the fuse, but the alignment of the markings. So, the question in my mind became, "What manufacturer would require, or even allow, employees to spend the extra time necessary to align the fuse markings?" I suppose in a fully automated assembly line, where fuses were originally packaged in alignment, and individually removed from that packaging and inserted by machine into the fuse block, all fuse markings could be aligned. But if picked out of a bin and inserted manually, the probability of all fuses being in alignment could be 1 out of 2 to the power of (the number of fuses involved minus 1). If my math is right, if ten fuses were inserted with no attention to the direction of the markings, the probability of all being in alignment would be 1 out of 512. That would be 19 or 20 cars out of every 10,000 manufactured. And that is for only ten fuses. For each additional fuse, the probability of all being in alignment is cut in half.
