| * small black: unused - black according to manual, but in fact purple. The purple signal measured 0VDC (With key on, but engine not running) |
| * YELLOW: output coil+ (appr. 350V DC : please measure this. Take care.) |
| * YELLOW: output coil+ (appr. 350V DC : please measure this. Take care.) |

* GREEN: Measures 11.8VDC with key on engine not running. While wired to genboard and cranking, shows mean voltage less than 5VDC which would indicate that Genboard is working properly GenBoard's ignition output => mallory's trigger input: a spark will be emitted at the rising edge. I have not yet measured the voltage of this wire with key on engine not running.
* there was also a purple signal that does not appear on the figure. The purple signal measured 0VDC (With key on, but engine not running) |
| * GREEN: GenBoard's ignition output => mallory's trigger input: a spark will be emitted at the rising edge. Measures 11.8VDC with key on engine not running. While wired to genboard and cranking, shows mean voltage less than 5VDC which indicates that Genboard pulls it down (to GND, but only for the dwell-time). Actually, 5V sounds a bit too low. Assuming VBatt=8V means pulled to GND at least 40% of the time, which is high for cranking RPM at given ign_dwell... settings (even for a v8). |

* There is apparently no anti-theft input (neither in the manual, nor in reality.
* indication of power (eg. LED): ??? * indication of trigger-input received (eg. LED): ??? |

* Exact EC36 pins:
Pin 10 is used for ignition trigger. |

Why do we think the ignition module is good?
* The engine ran with the CDI being triggered by the module, but still had problems dropping fire intermittently. The module is the common part that I want to eliminate and replace with CDI only. |

| ** a capacitor between green wire and ground. Very unlikely that this would fix the problem, but costs little to try. beware that, eg. a 10uF cap will delay appr. 500..1000 Ohm * 10uF = 5..10msec (unacceptable). So cap must be 10..100nF range: |
