WTD: 1981 911 SC CDI 6-Pin Box


Recommended Posts

Searching a CDI box for 911 SC 1981 engine (preferrably Melbourne) and depending on what the going rate is these days

Following some tuning yesterday after my rebuild I went to start the engine this morning and the engine wouldnt fire.  Conclusion is that I need a replacement CDI box

Fuel, but no spark. 

1. I tested the red 15 live wire to the CDI box and was reading 12.4V

2. I measured resistance between 7and 31d and no measurement.

3. cranking the engine, I had no spark from HD lead.

4. ignition on, I had near no voltage at coil (either terminal - white, not brown)

5. I opened up the back of the CDI box and this is what I found:



In hind sight, on a couple of instances the tacho dropped its signal, which a bit of research seems to be a symptom of a CDI box on its was out?
