My 91 500sl has developed problems with the turn signals, horn ,windows ,power top all have stopped working,I disconected the battery and the windows worked one time before quitting again .Has anyone any suggestions I would sure appreciate some help

 

How old is your battery and what is its condition. One MB I had had a dying battery that selectively shut down everything as it slowly died. A new battery and alternator fixed all the problems. Not likely but worth looking into since all your problems seem to be unrelated other than battery.

 

Owner of R 350. We had problem like that, it was the secondary battery under the front passage seat that went out. I didn't know we had two batteries. RVT

 

My battery is only 2 yrs old and fully charged .It all started working again 2 days ago but only for a couple of hours I think Ill try changing all the fuses next
