TM MINI2 no spark

Hello, I would like help with the repair of the TM MINI 2 engine. The engine stopped during training, it was preceded by more difficult starting on the transport cart. Finding the engine has no spark. Ignition Selettra 034-IG-75. We replaced the ignition coil but to no avail. The coil on the stator is measured to have 76 Ohms (the manufacturer states 80 Ohms). This was followed by the measurement of the stator coil using an oscilloscope. The current can be measured at about 13V at the peak. The ground wires are fine, so is the wiring. I’m at a loss as to what to do with it. Can someone please help me? thank you
