As you can see, i'm making a "realistic" vehicle that's capable of going to Mars, sure, it includes Pressurizing the entire thing, but, there's a problem.
Whenever i turn off the PUMP's to depressurize, i can't turn it on again, so i really can't pressurize anymore, Need help..
The pressurization system is based off from this save (REMO, for REsupply MOdule)
In some locations, the PSCN that turns the pump back on is conducting to some nearby NSCN, and through that to the 'off' wifi channel. This turns the pump off again.
I have added signs pointing to these locations, and moved the NSCN slightly so that conduction doesn't occur:
