Yeah I will have a look, the wiring is so simple compared to my Suzuki, which gave me some challenges. It's doing any damage thankfully. I've got another issue to deal with, my speedo cable was routed badly, so I routed it in what I think is a better and less curvy way. But now it's not engaging, so no speedo. Spin with a drill from rear wheel end and it works fine, so it's not the speedo. Turn the wheel and it spins at the speedo end. I think it's the wrong cable, 69" vs 65" so I will replace. But it's frustrating to 'fix' something only to break it. I have a feel for the speed in each gear and my brain speedo is probably 95% accurate, but that upstairs instrument is prone to failure at any moment.
Looking at wiring diagrams that appears correct and can explain the issue. I am using a master cylinder from a Yamaha Riva scooter. I bought it because it has a 12mm or ~1/2" bore. I looked for something compact with a brake switch and it works very well. I will examine the wiring to understand it. I remember being in a meeting once where a software engineer explained her error as an undocumented feature, with a straight face. I felt sorry for her as everyone laughed. But maybe that was her intent.
