so I went to my sl350 today for a drive after being left standing for a while ,it started ok but the batt lacked some whomph but I drove her and took the roof down which was fine however it will not go up !!! the roof switch just lights red and ding dings with a roof down sign on the left clock I have put the batt om charge in the boot to charge it up in case thats the issue. any other things to check before it rains ?
TIA Jason
