Guest Packardguy Posted August 17, 2005 Share Posted August 17, 2005 on my 54 convertible the top goes down just fine but I get no response at all when I push in the switch to put it up. I am going to get into it tonight, give me opnions on what you would look for first. All hydraulics are newly rebuilt. Thanks! also should I unhook the battery before working on it just to be safe?

Guest imported_49packard Posted August 17, 2005 Share Posted August 17, 2005 Get an electrical schematic off of packardclub.org. If it is hydraulic-I would start with the switch-then pump. Also check schematic to see if there is a safety switch that must be made before the thing will operate Link to comment Share on other sites More sharing options...
Guest Randy Berger Posted August 18, 2005 Share Posted August 18, 2005 Hmm? I looked for that wiring schematic on the PAC website but could not find it.The only reference I have is the 1948 convertible and that wiring digram shows allthe window and seat hydraulics and wiring but not the convertible top?? I guess itwas meant to be a secret. Can anyone else help out the gentleman? <img src="http://forums.aaca.org/images/graemlins/confused.gif" alt="" /> Link to comment Share on other sites More sharing options...
Packard8 Posted August 18, 2005 Share Posted August 18, 2005 The top control is a combination hyd valve & electric switch. Sounds like the switch contact in the "up" position is dirty or broken. In an emergency, you can "hotwire" the hyd pump motor and then put the top control in the up position and the top should go up (be careful not to go beyond the limit). The fact that the pump works in the "down" position indicates that the pump & cyls are okay, just not getting juice to the up contact. Link to comment Share on other sites More sharing options...
Guest Randy Berger Posted August 19, 2005 Share Posted August 19, 2005 What if the valve isn't functioning properly? Would that give the same result?Is that valve used for controlling power windows also? I don't have a 54 shop manual and the 22nd-23rd leaves a lot to be desired for information.Could he wire a test light on the output side of the top switch and see if heis getting juice out of the up position of the switch? That would tell him quick if the switch were at fault. Link to comment Share on other sites More sharing options...

It turns the hyd pump on via a switch and a valve directs the fluid to the bottom orifice of the double-action top mechanism rams causing them to extend and the top to raise.His post said ?no response? so I?m guessing the pump motor isn?t running when the control is pushed ?in?, but does when pulled ?out?. To me this narrows it down to the electrical contact in the top control that turns the pump on. If the hyd valve or rams were bad the motor would run but the top wouldn?t move (and the rear floor would be full of red fluid!) <img src="http://forums.aaca.org/images/graemlins/shocked.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest Randy Berger Posted August 19, 2005 Share Posted August 19, 2005 Thanks John for clearing that up. It looked like that from the 48-50 hydrauliclines, but the wiring for the top cylinders isn't shown. I think you've givenhim enough information to start on anyway. A combination electrical and hydraulicproblem can be tough. Electric problems can be bad enough, but adding the complexity of that hyd. valve sure does tax the gray matter <img src="http://forums.aaca.org/images/graemlins/grin.gif" alt="" /> Link to comment Share on other sites More sharing options...
Guest Packardguy Posted August 19, 2005 Share Posted August 19, 2005 Thanks guys for the info and advice. The man I originally bought it from told me he thinks it is just low on fluid and to check the reservior (spelling?) near the driver's side firewall. All the hydraulics are newly rebuilt and he didn't think it was electrical. I haven't yet been able to start on it but I will get into it tomorrow. Any other thoughts?

Guest Packardguy Posted August 22, 2005 Share Posted August 22, 2005 Got the top to go back up just fine. It was not a fluid problem but an electrical one. There are 2 wires that connect to the top switch. A green one that connects to lower and a red one that connects to raise. The red one was sort of contorted and not in a good position so I just kind of held it a different way and pushed the switch in and up came the top. I guess I should replace that wire or at least disconnect and reconnect a more secure way. Link to comment Share on other sites More sharing options...
Guest Randy Berger Posted August 22, 2005 Share Posted August 22, 2005 Thanks for coming back and letting us know how you solved the problem. We're also glad it was a simple fix <img src="http://forums.aaca.org/images/graemlins/grin.gif" alt="" /> Link to comment Share on other sites More sharing options...
