I have a 2005 Kawasaki Z750s and this weekend I was on a ride and stopped at a rest stop, and when I decided to leave, I turned the ignition on, pressed the kill switch on and the start switch and everything seemed normal for a second and then it just lost all electric power. After a few times turning the ignition on and off, I disconnected the battery, then connected it back and all of a sudden the bike started normally. I was riding it the rest of the day and the next day, did about 500km all together with no sign of problems. Anyone had any similar experiences, is it a sign of a more serious problem, loose wiring, bad fuse ? But the problem hasn't occured since, bike works normally.
