I did some tests
with a magnet the led nr2 goes on each time.
with the sensor reinstalled depending on the position of the prop the led lit max 5 times (with the coils not connected it's the same)
after installing 5 new spark plugs to the ignition leads. after several turns found a constant.
No spark when the leds lightends , ONLY the sparkplug of cyl nr 2 , after this one had a spark the led nr2 goes out and stays out
sometimes after that i heard a high pitch tone (like a highvoltage powersuply)
Thanks for more advice
Eric
