Video: Testing the speedometer of a 911G outside the car
Hi,
the video shows testing of a speedometer with a selfmade electronic circuit. It explains a lot about the function of electronic VDO speedometers: Doing electronics with a NE 555 to check a Porsche 911 speedometer - YouTube The video has a German soundtrack, but English subtitles are available. If you don't see them by default, watch the video directly at YouTube and press thes ubtitle button below the frame. Enjoy it, Jürgen |

iirc, Carreras use Hall, where SC's get the signal via ground pulses.
