ignore that bit! was thinking about a bison 50 as I was writing that reply! the charge points on a 1000 are on the side of the rail, in the plastic strip that runs the length of the rail, the pick ups (butterflys) are on the carriage, 2 sets of, make sure you don’t catch them and damage them when installing the carriage onto the rail
before you put it all together give them a bit of a clean with some very fine emery paper or scouring pad to take the burnishing off the surface and then dab a bit of dielectric grease on them
