Electrical help!
Hello do everybody.
Im finishing my project and ran into a problem when trying do get spark. It is a 72, 911 2.4 with webers, it seems do have somekind of sensor instead of contacts. There is a ignition module on the side (big alloy box 4 wires going in) There is Black, going to ignition sensor in the distributor. Blue/Yellow going to Coil + Ground Red going? Is the red wire electrical source? on the scheme it goes do fuse number 8 and seems do be + Also sensor in the distributor has black and red wires going in , as i understood Black is signal , and red is + ? Thank you. harri |

pictures are really required with this type of problem. it would seem to me that the red wire would be 12v switched power (ignition on power).
but please post pictures.

Thank you, next problem
when i connected red wire to 12+ ignition on, the CDI started to make noise. Is that normal? And also any ideas about the sensor instead of points in my distributor. Pics will be coming in evening. Looking other topics, i found out that it is a Petronix ignition. |

CDI boxes will make a high pitched noise when functioning properly.
