Hi,
Someone who has wiring diagram with colors for the cables to BSA Sloper from 1930?
Attached is the wiring diagram I used for my 1929 Sloper. No colour index but I managed ok using only black wires all labelled for ease of doing it. I don't recall seeing a 1929/30 wiring diagram with coloured wires. Attachment is reduced from 3.1 Mb due to Forum restrictions so smaller than A4. Hope this helps.
Thanks for the answer.
Seems like the cable ends are identified using a colored sleeve.
