I made a big mistake, I inverted polarity of Sparkswitch (futaba transmitter, SRS competition, Zenoah 62-PCI)
During this period of inversion , the Sparkswitch’s LED lighted ! !
And sometimes the engine started. But mostly the engine didn’t start.
My question: had this inversion damaged the Sparkswitch?
You are not concerned by my second question but I’m asking myself if the Zenoah’s ignition module is damaged by this inversion.
