Scott,
Yes, I saved one of your posts from some time back, and with the schematic helped me understand that I melted the down solenoid by powering it while I had the pump CB pulled, so there was no pressure tofor the pressure switch to cut off the solenoid coil voltage.  A replacement solenoid NAPA ST81, has a note withi it stating it shoulod NOT be used if there's an on-board computer, adn as I have a GRT dual glass panel I opted to add the diodes to both solenoids, although ti seemed to me a better fix wold be to substitute continuous duty solenoids with integral diodes.

I'm airworthy, but am going to install an MT prop before I fly... it's due this week.
