First of all, I am using a classic valve with level x tuned for a different body/rail/grip. But the emag valve needs a complete rebuild, guy obviously used co2 and turned all the orings into goop.

So here's what is happening. Using two fresh nine volts together in a series, (18.5 volts), the board boots up. Heck, the marker even pulls the solenoid down if you push the solenoid up, when the gun isn't aired up.

That's as far as we get for the good. Wen the gun is in electro mode, once I pull the trigger the board goes blank. And when the gun is aired up the solenoid does nothing. The hall sensor appears to work, as the board will not turn on when the trigger is pulled back. With the trigger forward, the board will blink the pixel. With the trigger pulled back, the pixel does not blink.

The trigger pull also seems to be rather heavy when the gun is in manual. Manipulating the sear when the gun is not aired up is also similarly stiff.

Can anyone please help me with this major problem?

Here's a picture of the board and noid,

Here's a picture of the selector switch from the top, in case that matters.
