Several weeks ago I posted about some electrical issues I am having with a 93 300sd. The battery went dead from sitting and we jump started the car,everything was working normal and then the instrument cluster quit working.I disconnected the battery and charged it with a battery charger,when I hooked the battery back up everything worked normally.I drove the car about 5-10 miles and the next day it all quit working again.In my previous post it was suggested that I check and clean the ground from the engine to the frame and replace all the fuses,did all that plus cleaned all the grounds under the hood that are hooked to the body. I still have nothing except temp gauge.Any and all suggestions welcome and greatly appreciated. Also would anyone have a link to the instrument cluster wiring diagram? Thanks for the views and any comment/help.
