Attempted to determine why I had an intermittent voltage at the switched power plug mounted in the left hand knee pad. Unsuccessful to the point I probably destroyed the BMW illuminated rocker switch mounted in the small rubber dashboard mounted at the handle bars which supposedly supplies switched power to this outlet. However after stripping the rocker switch out I am puzzled that the switched wire does not appear to go directly to the power outlet.
Simple, simple, simple, three wires to the rocker switch, Brown is negative, Blue/White is positive and energized all the time. Brown/Yellow who knows where it goes and why.
Then at the power outlet two wires, brown (negative) to the outside of the BMW female plug in the knee pad but lo and behold there is a Red/White to the centre pin of the power plug not the Brown/Yellow from the rocker switch.
The third wire leaving the rocker switch (the switched lead) goes somewhere before it becomes a Red/White wire on the positive power center pin of the female outlet.
Am I missing something here? Are there interposing relays for the power outlets on this bike?
I can wait and chase the wire once I stop riding and put the bike up for the winter, Unless someone has a simple answer for me on the wiring logic of this bike.
I looked at the schematics but it doesn't appear that this power outlet is connected to the load shed relay.
Any thoughts are more than welcome.
