Trouble shooting hydraulic tilt trim issue

[MoneyPitBoat]

I have been restoring a boat over the last few years. I replaced the stringers and transom. I am now getting the hydraulic tilt trim back on a 115 horse Mercury outboard. It is a mid 70's mercury. I hooked everything back up from my feeble memory and I can not get the hydraulic motor to work. I bypassed the trim limit switch since it show no continuity. I can jump the down post on the solenoid and get some noise like it wants to pump fluid but I can not get the same result from the "up" blue wire post. I wonder if the solenoid is bad or if I have hooked the wires up incorrectly. Can you suggest what I might try.?
