With the positive meter probe on a live point and the negative probe on C0286-9/10/11. My assumption was that when the brake pedal is
not depressed, the switch is open between pins 2 & 4 and therefore the earth should not be made from the LSM. It's behaving though as if the pedal was depressed if my logic is correct?

That's my point. I don't know. I also checked the LSM switch pin 25 which shows as running to C0286 and then to C0775-4, which also made to earth. Am I wrong in believing that pressing the pedal closes the switch, completes the earth coming from the LSM, and illuminates the brake lamps?
Brian, what was shown on Jamie's screen was exactly what you've put above on the third photo although I'm now unsure whether switch 1 was on and switch 2 was off, or vice versa. I can see it's relevant so I've PMd Jamie to see if he remembers.
Dougie,
