No power to CIS? 1991 560SEL
It seems my 560 is running fully mechanical as my multimeter shows no power at any of the electronic inputs... the flapper potentiometer, cold start injector, EHA, etc and idling high. I can only change idle via CO screw.
These CIS ECUs seem to be pretty durable, has anyone experienced a dead one before? Any definitive test I can run to see? Thanks
