I did the test with a 55w bulb, I put it in series on line + b to the flayback, I gave it a light and the flayback sounds and the bulb turns on normal ... all this with the tsh connected, then I took it out and measured it for what you told me and that's fine, I already sent you the measurements ... will it be the flay that is fried then friend victor?
