Tag,
No problem.
But do me a favor. If we are helping you and you can, please join the club.
I can take a picture of my rams if you want. I think the hole at the top
was used by the hydrolics. The piston was pushed up and down, so they had
to get pressure to both sides of the piston. With the air doors, the hole
simply allows the air that is compressed by the piston going up to escape.
The down solenoid is "T"ed off of the pressure line going up to the cylinder.
So when the doors go up, the lift ram is pressurized. When the up switch
is released, the up solenoid closes and the air line, lift ram and the input
to the down solenoid are all pressurized. When the down solenoid is energized
it opens and lets the pressureized air out through the bleed hole.
Hope this helps.
