There are a lot of things that I wish I knew for certain, :} Sorry I just was not seeing any of the lights in the seconds before landing and of course we did turn off all of the power about the time we quit sliding. I can't say for certain that both switches were activated when we turned the power back on, but both relays were HOT with the gear switch in the down position..

I do appreciate your investigation!!!  I dont like mysteries. THANKS

Not a matter of high pressure overpowering the low pressure.  The pump normally runs in one of two directions that supplies hydraulic fluid to either the low pressure or high pressure port depending on the direction.  Applying plus voltage to both lines causes the pump to run - in what direction???????  I have a old pump out at my hangar and I will perform this power experiment under controlled conditions, perhaps today.
 
Did you note if the transition light was on?
