Does anybody know or have a diagram of how the softtop works?
I hope the attached helps you. This comes from the Model 129 STAR Classic Service Manual DVD that you can purchase for $88.00 from Star Service CDs and DVDs . If you Search the DVD for "ra77001290010x.pdf' you will find the attached picture and much more.
The operation of the soft top control system is surprisingly simple. The controller executes a step-by-step sequence of motions as illustrated by the document Lynn posted. The completion of each step is confirmed to the controller by inputs from switches that detect the position of the system's mechanical components.
Scorpiox, your problem probably has to do with one or both side windows. They are not part of the top mechanism, but the windows still figure in the sequence. The closing of the top (Step #16 in Lynn's diagram) is interrupted if either side window is not completely lowered. This is where it seems your top is stopping, and if your windows are in fact lowered, then the specific problem is likely a limit switch located in the bottom of each door that closes when the window is fully lowered. This is most easily confirmed by reading diagnostics from the top controller. If you are interested in this simple and easy procedure, you can search the forum or send me an email.

I tell you what, my week-old 2001 SL500 is running beautifully (a very high grin-factor) but if/when anything ever goes wrong I sure feel better knowing that this forum is here. I've participated in any number of forums over the years but the knowledge and experience available is truly a stop above ... many thanks!
