Ah, well I misunderstood. I was assuming the electrical
system was separate from the pressurization system. Check valves
won't work with wires running through...
But if you're running trolling motors, they are mounted to
a hollow steering shaft. Wires run through the shaft to the
battery and the control head. Tubing can also run through the shaft
to maintain ambient pressure in the motor. If the tube
pressurizing the motor on descent has a check valve, then you need another
tube to bleed pressure from the motor on ascent. The shaft is then filled with
sealant of some type... silicone, or bondo (automotive dent filler), so that the
individual components are isolated.
At least, that's how I plan to do it... Unless someone sees a
flaw...
