thank you Jap and oros27

I found the error :
the resistor R44 was damaged, I changed it.
So I see the signal of the test.
But always, I have not got a good result (long depth), I think that my coil is not good.

thanks

ok jap check irf 740 bc the 337 and put a diode byv 28

[volcano]

ok Jap, I understand
you want to say that the quality of R=4.7 k and 680 is bad
and IRF740 hot.

So I will do all what you requested from me

thanks
