1985 500SEL idle control module
 

Is there / does anyone have, a schematic for a 1985 W126 V8 idle control module? Mine appears to have some issue and I'd like to trouble shoot it instead of taking it apart again and again. It's either a flaky component or a bad solder connection. All the solder connections appear to be ok. So I'm thinking a flaky component. Or should I just run the all the solder connections on the board? Heck, even a wiring diagram showing the connections to the module from the vehicle harness would be of benefit.

I'd resolder just the main connections to the pins. That has worked for others in the past.
Sorry i don't have the schematics.
