Could somebody with an installed 914 please tell us how he has wired
his pumps and which pump is switched off during flight?
I am a bit reluctant to do what Andy says because we are using a
master solenoid near the battery which would make both pumps powerless
if the master switch (either intentionally or accidently) is switched
off during flight.
