Damn, I had my pin 2 at the junction of R3 and C1, which worked somewhat, but now that I move it down to C1 R4 the LED stay on all the time. With that config, LED always on, it’s 180mv from pin 2 to GND. I don’t know if this is right but the other side of C1, the C1 R3 junction, it’s 11.4V.
Replacing C1 with a link shows 4V at R4 R3 pin 2 junction.
PS : Is this annoying yet 
Because i bet if you were here you could fix it in 1 min.
