In about 2003, a friend of mine bought a Bimota motorcycle. Absolutely amazing machine hand-made in Italy using either a Ducati or a (Kawasaki?) engine. I think his was Kawasaki. New in the 1990's, they were $30 grand when a new Harley loaded dresser was half that. Beautiful machine, engineering and workmanship.
Except the wiring. The wiring, it seems, was pieced together from whatever was lying around the factory. Use a new 6 foot length of wire for a circuit? Mama Mia... no! Gorlami! Take a piece of black wire and a piece of green wire and splice them in the middle with shrink tube and then run through a conduit and hook to the circuit. Wiring diagram? None. No wiring would ever need to be done on an Italian bike. There were 3 feet pieces of wire made up of three different pieces of different-colored wire with two splices. Red goes in to the conduit, green is 'in' the conduit... and pink comes out of the conduit.
Needless to say, every wire was removed from the bike (buddy is an EE) and completely re-wired. Which was a nightmare on a complex sport bike, even with 1980's technology.
Remember this: The best car in the world will be styled by the Italians, engineered by the British and Built by the Germans. The worst car in the world wil be styled by the Germans, engineered by the Italians and built by the British.
It's funny because it's true!
