Problem 86 300SDL-all at once-lost tach,compressor,ABS lite,has low idle
Hi, new to the forum, but not MB's
Problem: Pulled out of the driveway the other night and in one feld swoop, lost the tach, compressor, ABS lite came on and idle dropped. Shut it off, waited a few minutes, started up again and everything worked for the rest of the evening. Next day, same thing and then today it started with this issue and hasn't returned to normal. I traced all the schematics in the factory manual but haven't found a common denominator. Checked all the fuses and connections even remotely associated with these items but to no avail. From the schematic, the suspects that may be related to all these components are the EDS (electronic diesel control system), voltage overload and ignition switch but none of the suspects cover all of these without affecting other components.
Rather than throw parts at the problem, I thought I would see if anyone else has had this happen or could possibly shed some light on the issue.
Any help is greatly appreciated.
