I have a new BME 102 EVO thatran great for the first 12 flites then it started acting up, quit in the air and would not start. Tried again today and isolated it to the ignition system. I was not getting any spark but when I plugged the battery in to the ign directly( to check the switches) it would spark. No spark by prop rotation however. This would lead me to suspect the H.E. sensor or the ign box itself. Are the sensors prone to failure.
I ran a Pro-spark for years and am familiar with intermitents in wiring. I checked under all the heatshrink and could not see anything but one has to almost cut or redo the wires themselves to be sure.
Is there any way to check the sensor with a multimetre? I see on C&H site they have an ignition tester. Are all three wires active?
I also had a plug cap come off in flite. I noticed the Bosch metal cap version but does the NGK short reach plug work in the BME?

Yes I emailed BME but I want to be back torque rolling soon
