95 SL320 convert roof problem

I moved my car outside today with the roof down. It has been sitting inside for about 2 weeks, I went to put the top up and it stopped half way.
Fuses are all good, I charged the battery( which I think needs to be load checked, it's about 5 years old).
No hydraulic leaks and the reservoir is full.
My best guess is the battery is shot or it's a mysterious relay.
Any advice is always appreciated.
Thanks

Start the car and keeping it running while you operate the top.

This typically indicates that the windows are not "synchronized". If you open a door and the window does not lower 4mm automatically, then this too indicates the windows are not synchronized.

You synchronize a window by pressing the switch to raise the window and once the window is all the way up continue to press for an additional 2 seconds.

The battery was load tested and okay.
I started the car and tried to sync the windows, but nothing works, windows top, roll bar, nothing.
i removed the battery yesterday, hoping that will reset something...so far nothing works.

The most likely explanation is that you have a blown fuse. Check all fuses in general and particularly fuse #6 in the main fuse box and fuse #3 in the trunk.

Problem solved.
1 removed the battery and had load tested, it was fine, Charged it.
2 manually locked the roof down, front header, tonneau cover, rear top.
3 reinstalled the battery ( fully charged )
4 ran the windows up 3 times
5 with windows up, cycled the roof up and down and up again
6 with the windows up, opened the door to see if the window dropped a 1/4 of an inch like it should.

Its a miracle, fixed in time to put the car in storage
