Loncin 250cc Quad No Spark Issue: Replaced Ignition Coil, Module, Wires & More - Seeking Advice

Hello
I have a problem in the ATV described above, such parts have already been replaced:
-the ignition coil
- ignition module
-wires, pipe
- own installation so that there is only a spark.

The coil checked with the meter, the resistance is fine, i.e. the charging coil has a value of about 300 and the pulser 141, so it's ok, the mass is everywhere, the problem is exactly on the black and yellow wire that connects the module with the ignition coil because, as far as I know, it should be on before the voltage of the order of 10-12v during the shooting and it should be variable, and this value during the shooting increases to different values and then drops and after stopping the turning with the starter, the value jumps again so much that it is negative and goes down and the question is what is going on?

I am asking all forum members for help, any suggestion will be helpful.
Greetings.

Check the cable in the ignition module responsible for extinguishing, if it connects to ground, there will be no spark, you can try to disconnect it from the module and check the spark.

Tried disengaging and nothing helped.

Take photos of the impusator coil module and engine cubes and post on the forum from the photos something will come up sooner

such a set is there like here https://www.google.pl/search?client=firefox-b...cin+250&oq=iskrownik+loncin+250&gs_l=psy-ab.3. .0i30k1.22362.28275.0.28547.20.20.0.0.0.163.2574.0j19.19.0 .... 0 ... 1.1.64.psy-ab..1.19.2567 ... 0j0i67k1j0i24k1.Q__g5QRQgmk # imgdii = lzMvaUC_xBUc98M: & imgr98M: & imgr98M = K2IAH1y-a-wdLM: only the colors are different

This is a lot of possibilities, since you bought a new module, the coil requires 2 cables from the motor, not counting the weight, and one for the coil from the module to fire. Check all cables possible that you have mistaken the cables for the charging coils as the module's power supply. You should be feeding it from that one larger coil.

no, black and red is from the module's power supply, blue is from the pulser, green is ground, white and yellow from the battery charging

And which coil does this red and black one go to?
I already repair a few magnetos and 50 percent of the damage is the module power coil has very thin wires wound and in the place of connection on its side to the wire these thin wires break off, the other 50 percent are modules

but if it was the fault of the coil, I would not have about 12v on the module, i.e. the black and red wire, maybe the ignition module is damaged, although I put the module from the quad 110 and the same

And in 110 this module worked.

so even 2 I have which I also assumed

This is something wrong with this modul power coil

And if the pulser was damaged, what would be the symptoms with voltage on the black and yellow cable?

The spark could occur, but not regularly, but from what you wrote, I measured it. In addition to checking with the meter, I put the cable from the pulser to the engine and turn the starter as it sparks when turning it, it recognizes that it is ok. The method is a bit stupid but effective, I do the same with the power coil, sometimes the meter shows that it is ok, but it is linden under load.

and thanks for the advice I'm checking tomorrow

Let me know what you can determine. greetings
