I have a problem that I cannot find listed anywhere in The Tech manual or in The Forum. My CIS works on my 1969 280SL (w/o A/C), but it works in reverse: It does not move the linkage when the car is put into gear, but does move when the when the car is put either "P" or "N". This is backwards; it should engage when the car is put into gear, and then increase the idle speed to compensate for the increased loads, correct? It idles smoothly at 750, but increases to about 1200 in "P" or "N" (also very smooth). Is it possible that this device is wired incorrectly? I checked the Site Wiring Diagram, but it states that is incomplete/incorrect as to "Idle Increase Solenoid" wiring. Any ideas?
