I was looking at the wiring diagramme in my Service Manual and noticed that the wiring for my Ignition Coil does not match what the manual says it should be.
Attached is a diagramme of my coil, and three photos.
The manual has the yellow from the starter going to the same post as the ignition resistor wire, and the black primary lead wire going to the other post.


You can see that mine is very different.
How can this work?


Also, I have an extra black wire from the engine harness with going to the same post at my yellow. What is that for?

Looks OK to me, for something converted to w/o pts.

does it not run?

It should look like this, the condenser on the coil goes to coil +, your electronic ignition may or may not use the resistance wire.

I think I was all mixed up on what wires are what.


The black wire coming off the positive is the ignition wire (part of the harness), along with the yellow from the starter (also part of the harness).
The brown wire coming off the negative terminal, connected to the braided/shielded wire is the aftermarket tach wire.


Sorry for the confusion guys - I'll take a nap and feel better.

The condenser on the coil goes to the positive post for radio noise suppression. It looks like it's on the negative side.

Eric! It certainly isn't doing any good sitting at the bottom of the well (energy wise).
Thanks, I feel so sheepish not seeing that.


It is a good thing I have a recent aftermarket radio with built in filters. I am missing the condenser on the fan blower as well as the regulator, so basically have been running with no original-specified noise suppression.


De soun's still soun' well! (Bermudian vernacular for the radio still works well- you have to say it out aloud phonetically to see the meaning).


thanks Mate.

Hahaha, it does make sense when you say it out loud. You don't need the filters unless it's needin filterin.
