You didn't see anything in the box the new coil came in did you?



Oh, and on the wire colors. Some manufacturers use white instead of yellow.

Yeah I did look in the box.  It only had the new coil. Nothing else.  Let me ask you something else.  What about the ground wire that is in the picture? It does touch all metal with the coil?  Is it becauser the coil then sits it the plastic housing?  I will look for the ground strap in the meantime.

Based on all this from this post.  I realize you can't see everyhting I see, but should this Tach do something? If I can ground this properly should there be a positive result?  Thanks for your help

The wire that screws down to the the corner of the coil should have the other part attatched to it. I believe you get that when you buy a new cap. There will be a little bag with the rotor button with spring attatched, a rubber isolator ring, and the ground strap/ plug.

No, I just bought the coil.  I had the car tuned up about 2 months ago.  They replaced the cap and rotor.  I don't think they replaced the coil so I did today.  They may have replaced the coil, but it looked pretty rusty(see pics).

It didnt looklike they replaced it, ( I usually clean the cover when I have it off also) looks like they didnt replace the module either.  Go to your parts place tomorrow and ask for a cap, when they get it, open it and see if that strap/ground plug is there.

I'm sure it was replaced because when I bought the car the cap was a different color.  I'm not sure of the module.  Great idea about looking at a new cap.  Hell I'll by it all if I can get the damn Tach working again... ;)  It's bizzare because even with the old cap it still didn't work... Unless the ground strap was missing from it as well???

I just had a thought. Some of the early HEIs used a wire like this one rather than a metal strap.



If you are not able to find a strap then you might be able to make one similar to this using a piece of wire, an eyelet connector on one end and a male spade connector on the other. Then just push the spade through the center slot and into the connector coming up from underneath.

I would also recommend that you use the same screw for both the strap and the ground wire coming out of the coil just for continuity.

I think LOMILETA is right about caps coming with those straps too. I'm pretty sure Delco caps as well as coils are supposed to have those.

This is getting Funny... I went out tonight, started the car, turned on the lights, ..........Everything was dim on the inside.  courtesy lights, dome light, gas gauge not working, volt meter not working, dash lights(dim), turn signals showing they are on but no flash.  I assume it's a ground issue, but who knows at this point. Any ideas???

Is it possible when I removed the cluster so many times this week that the printed circuit(as bad as it is) ruined the ground?? I believe that all these problems come from te same circuit??? Am I wrong?
