Leak down test on the LP gas system, leak detected.

I think it's going to be the valve, but 1st this video

Edit: more like it opens when not being told.
NOT Valve, control...

Check for continuity (voltage?) across the 2 blue wires before and after water column drop. And battery voltage across red/yellow.




Edit again: that's strange, even without the control board plugged in I detected gas in the exhaust port. Hmmm...
