You said the engine stopped at the trafic sign , that can happen if you close the throttle rapidly, no problem.

Then you was in a hurry to get the engine started, maybe you forget to pull the clutchlever, or the sidestand was not completely retracted?

Trouble shooting electrical problems start at the source: the battery and its connections.

Then work your way up to the component that's not working.


                 Electrics? It's like magic, read this:

One day I started by bike to go to the gasstation to refill.
When I wanted to start again the only noise was a rapid clicking sound from under the seat, what the F%$#k.
Pushed the bike home and after taking the seat off I discovered that the sound came from the starter solenoid. Luckily I had a spare so replaced the sol.

Bike started right up, problem solved? NO WAY

Started the bike maybe 5,6, or more times over a period of a couple of days.

Then , one day , nothing, no juice, only the green neutral light and when hitting the starter button no lights at all.

Battery flat?
Decided to take the battery out and recharge it.

Seat off again to reach the negative terminal.
Well, that was the problem: LOOSE connection

Also the CDI works only when powered by electricity, maybe an intermittend loose connection that caused the engine to stop.


Happy trouble shooting.
And when you're at it also check the general negative wire. That's the little wire attached to the big negative wire. It has a connector about 8" away from the battery: disconnect, clean and reconnect.
