As posted in a previous thread I'm starting the restoration of the convertible top frame. This topic is about the power top cylinders. They've been sitting disconnected from the system for 25 years. They didn't leak back then but I don't know what toll the last 2 decades had on any seals. I hate to install them, fill the system w PS fluid only to find my rear floors covered in fluid. Anyone out there know anyone who has a test stand? I've been told that I can hook up the pump lines to the cylinders (I have a spare pump), fill with fluid and use a battery to power up the pump. Supposedly can be done on the garage floor. I have reservations as I know the pump is grounded to the car body, there is a resistance jumper wire from the stater solenoid to a relay on the apron, plus a switch and some resistance from the top assembly on the cylinder pistons. If I do the home garage floor test will I burn up a pump and will I ruin potentially good cylinders. I would consider new cylinders but those which seem readily available don't seem to look like the originals. They seem to be generic one size fits all.
