[QUOTE="LCP, post: 211559, member: 2424"] Okay okay, very sorry guys, looked up both my Haynes and Bentley service manuals for E36, there is no cut-off at the crank position for many items... I must have been looking at too many circuit diagrams of cars already, I have got this, errr, "fetish" for schematics diagrams since I was a kid, can't take my eyes off them the moment I see one. Here's what happens in my car... on the aircon compressor, no way to turn it on if the engine is not running, only the blower and aux fans will run if the ignition switch is turned on, and the compressor will only come on a few seconds after the engine has been started, if the aircon is left on when starting. My radio cuts off fully when the ignition switch goes into crank mode, and will reboot again after finish cranking... As for my headlights (excluding position lamps), can't turn it on (in "off" or "acc" modes) unless the switch is in "run" mode, not sure whether it cuts off when in cranking mode. [/QUOTE]
