Electronic ignition
It's been a long time since I played down this road. Some terminology may not be correct.
Vehicle has a 327, seems to be factory electronic ignition. I seem to have no spark at the plugs. Cap, rotor, look ok. Removed coil cover. Checked wires, seem to be good here too. Removed coil. Removed black washer/insulator. Removed spring but a part was left in the dizzy....  Looks like it's broke....  Would this be my issue? If yes, what is the name of this part? Thanks much...Don. |

Re: Electronic ignition
Thats the carbon button that connects the center tower in the cap to the rotor. It's usually positively retained in the cap - not sure it can be replaced outside of replacing the cap...?

Re: Electronic ignition
That part being broken is consistent with your no spark symptom.

Re: Electronic ignition
Is this factory electronic ignition actually a transistorized ignition? Or just an hei.
It might be worth a chunk of change! You got pics of it? Last edited by geezer#99; 11-02-2024 at 02:28 PM. |

Re: Electronic ignition
IIRC it's a GM HEI. This is the best pic I got....
 FWIW....Im not a mechanic outside of shade tree maintenance. This issue is in the wife's toy....  She likes it...Don. |

Re: Electronic ignition
Don't see too many of those - nice!
Make sure the HEI is getting a full 12V as well. |

I got 11.74 volts. At the battery I get 12.6 volts. Is 11.74 close enough? Thanks much...Don. |

Re: Electronic ignition
Update. Friend who knows more about electronics than I.
HEI wire is powered in fuse box the ign unfused stud. I get 11.74 volts at the stud. Batt = 12.4v. Got 11.74v power to the HEI coil. Got no power to the ignition module. R&R module. She runs like a scalded dog. Thanks all....Don. |
