Larry, I finally got some time
to troubleshoot today. You're right about the high pressure switch.
I wired it out of the circuit with a manual substitute which controlled gear
retraction just fine. That pressure switch is about 2 years old with only
10 flight hours on it. No idea how many gear swings on the ground were
done.
Thanks,

I'm hearing broken wire on
the up side pressure switch circuit. It is a normally closed
switch. When the pressure is attained the switch opens to turn off the
pump. Perhaps the connections have failed or the switch has internally
failed.
Good
Luck,
Larry
