Well... for a few days the T250 has been like a dream, until today when driving couple of miles, it went complete dead.

There is fuel on the tank, new sparks, new rectifier, new batteri and everything seemed fine.

I suspect the generator to be broken, but have no idea really.

Any idea about this? Can it have something to do with me connecting the r/g cable to the g/w cable?

You had a problem in the wiring harness &/or switch.
Connecting the r/g cable to the g/w cable bypassed that problem.

Most likely the wiring harness &/or switch problem has gotten worse to the point your bike doesn't run.

Did you check the voltage with a new H4 headlight installed?
Did the fuse blow?

Hello

Yes I checked, and no fuses blown and the light seemed OK.

I just checked the voltage on the battery, and it was about 13 Volt.

Will check voltage from the alternator later today.

And I will de-attach the wiring I put up to see if that makes any change.

I try to start with the kick, and at the same time measure voltage from alternator...

Even though the engine do not start, I can see the voltmeter goes up 6-7 volts for a short time... as long as the kick is stepped on.

The same with the power out from rectifier - some 5-6 volts

I have disconnected lights, and other stuff to check if there are som reaction.

I can find only one fuse, and thats in connection with the rectifier. The fuse is ok. The battery stays at about 12-13 volts.

But still... no 'spark' or signs of engine to start. Its just complete dead.
