Derbi Senda Xtreme: Loss of Spark After Rain Exposure and Engine Shutting Off During Ride

Hello!
My problem is that when I recently drove the Santa, which I parked in front of the house and after some time it started to rain heavily and it was raining all over the electrics and everything. I got in, it fired normally, I drove maybe 3 km and suddenly it went out while driving. I was surprised, I tried to fire again and it fired normally, I drove with 500 m and went out again. I took her to the garage. The next day (it was already dry outside) he tries to fire it. Normally it fired, I drove 1.5 km and I turned it off after a while I wanted to light it, it lit it for a moment and then it went out. The next day it tries to light it and it fired for a while and then it went out. Before firing, I checked if there was a spark and it was there, but after firing, when I checked the spark again, it was gone.

What ignition? Leonelli, Ducati or Kokusan?
I would start with disconnecting the extinguishing from the module, depending on the type of ignition it is solved differently.
It is very possible that it flooded the ignition switch, ignition switch or installation and the resulting breakdown cuts the spark.
Otherwise, there could be a damage to the power coil on the stator (interturn short circuit), it would be a coincidence with this rain, you can only diagnose it with a meter.

Ignition ducati energy

This is why you disconnect the cable from the "stop" terminal of the module's coil, or in the second version, the plug with two wires (green, yellow) between the stator and the electrical installation.

I did it and it has a spark, what can I connect it and it will be a spark or something

And how do you turn off the bike afterwards? Shifting into gear, holding the brake, and releasing the clutch until you stall the engine? :P

You just know that you have a fault somewhere in the extinguishing circuit. That is, to check the wires from the module, through the steering wheel switch (if any) to the ignition switch, and finally to the ground .
Nobody will tell you any more. Look for signs of corrosion, such white raid, muck, water, etc. All cubes, connectors on the way also to be checked.

Well, only that is the magneto is ok, the module also only a beam and ignition switch and mass I know that at the back I have something unfastened that there are two black cables on the back on the screw and I do not know what it is for
