1998 SL500 Soft top problem after top cylinder rebuild
I have just did one of my top cylinders this weekend. Rebuilt the seals myself with a kit
When I put it back on and tested it the top started working but it looked like the it was still leaking fluid and quite a bit
The windows will cycle but everything stops after that and the light is solid red on the top switch
Also, the roll bar does not go up or down now as well
This is for a 98 SL500

- I may have scored around where the metal clip to hold the cylinder in getting it out

This is for a 98 SL500
I have
- Cycled through the manual top up and down
- Did a roll bar reset
- Did a windows reset
- Checked fuses
- Checked health and charge of battery - all good
- There are no fault codes
- The micro switch on the cylinder was not damaged in removal and repair
- Hydraulic fluid is full

CHECK EVERYTHING YOU TOUCHED. More than one person failed to reattach the microswitch assembly to the top cylinder. The top controller waits for the 'microswitch' signal before going to the next step. Check to be absolutely certain the microswitch assembly IS correctly installed. Also probe the wire connection to ensure switch does work and signal is being made, then test same at the computer input connector.

It did start working until I saw that fluid was coming out again
- Would that have stopped the process?

That 'it worked-then stalled when oil leaked' tells you the leak in the leaking cylinder is big enough to keep that cylinder from fully actuating, not closing / opening a microswitch. The 'computer' will stop right there, waiting for that un-actuated switch to open/close You will have to fix the leak.
At least you proved the pump and computer and valve block are properly working..

I tested that theory yesterday as I pulled some top cylinders off a wreck
While I do not know if this one leaks it did not engage the system at all
It was working previously with the small leaks in the top cylinders

I can always send it in to them and may do that
The issue is I am in Canada and shipping makes the cost much more since the border is closed
I used to be able to get it delivered to a parcel locker just below the border
