Badbob, Thank you for checking.
Apparently Suzuki changed the wiring such that the break light works even if one of the lights fuses is blown. Provided you use both brakes. One of the fuses 'feeds' to the break lever and the other one to the pedal. Their intent is probably to increase safety.
Well everything works like it should now, and in due time Suzuki will publish a new wiring diagram for our "03" type models, so until then we'll have to do with the 1999 diagram.
PS instead of "break handle" in my previous posts please read "break lever"...English...
