I went out for a short ride yesterday and half an hour in, the engine died and the red triangular warning lamp came on.
My reaction was to press the rear brake pedal, which extinguished the red triangular light, and the power came back.
I initially thought that the back brake had came on via the ABS, which is why I pressed the back brake pedal.
but then realised I had lost all power momentarily.
I rode for another half an hour, then whilst coasting to a stop light, the bike died again with the red triangular light coming on.
I pressed the starter and she instantly fired up, and I got back home with any further problems.
Recent maintenance as follows.
1. 50 amp alternator and new motobatt battery fitted.
Battery charge indicator bulb then flickered occasionally for 50 miles or so and steady after with a good charging rate
ABS lamps began to stay on now and again after operating both brakes, so swapped ABS brain for known good spare, ABS lamp goes out every time .
2. speedo signal failure from rear drive sensor.
No problems since.
I noticed that when I switched the ignition on, the instrument lights were just about visible. Turning the key back and on again, the lights were as they should be. I could feel the switch was a liitle rough when moving it slowly
Obviously my first port of call will be to clean / replace the ignition switch.
My question is, why did the bike power come back the first time, when I pressed the rear brake pedal which extinguished the red warning triangular light?
Would dirty contacts in the ignition switch do this?
Have ordered a can of deoxit equilavent.
