Title: DId a 69 Z use the capacitor on the coil?
Post by: BillOhio on June 16, 2016, 11:27:35 AM
I copied this from a post Danny made. John left this reply. I am pretty sure i had seen them with the capacitor but i didnt find it in the AIM. Thanks!
coil bracket with the "notch" is not unique to the Z/28; originals don't have the notch, although the eBay sellers want you to believe they did, so they can claim they're "rare". The one in the photo is clearly from another application, as it has the screw to attach the radio noise suppresson capacitor, which was never used on a '69 Camaro.

Bill I don't have access to my '69 AIM right now, but I was under the impression the capacitor was shown in UPC U63. Perhaps I'm thinking of the capacitor on the voltage reg?

The way I interrupt the AIM on this is that the U63 and U69 are combined and there are callouts for the U69 option.  Look at the whole AIM page including the title block.  This may help answer your question.  BTW no capacitor on the coil bracket.

My bracket shows no sign of anything being attached to it, no threads in hole. Here is a picture from the Dusk blue car 69 Zee.

I guess you could say never say never.  Still need to investigate more.  Could it have been added at some point early in its life.?.  Maybe. Is there a way to know 100% probably not.

I think with my not having any signs of threads I should probably not put one on it. Have a good one Darrell

Bill, I *think* (and that's a dangerous thing) the throttle return spring hooks into the hole where the capacitor bracket is mounted in your picture. BUT...I'm not certain which car my memory has revived. Coulda been a 350 (my El Camino) or a 396 (69 Impala)

Bill was your car an AM radio car?

Yes. I looked at the AIM and it looks like some of the drawings were after my car and I don't have the wiring on the heater motor like they show. Maybe just FM radio stuff

The greenish throttle return spring attaches to the the rear plug wire stand on the Z.  There's a tab with a hole for it to hook into.

I thought that bracket looked familiar..lol.  I have a few other pics of original Z engines and they're also showing a capacitor attached to the coil bracket.

Hmmm...interesting to know though

Helps the points last longer so why would it not get one?

I don't recall any mounted to the bracket. The cap used with the fan motors, came on cars equipped with am/fm and was for noise suppression.

Yes the capacitor attached to the points is for arc suppression to preserve the points.

Thanks guys. Mine shows no signs of having a screw in it.

So would it be safe to say that the capacitor may have been added to my coil bracket (pic that BillOhio posted #8) at some time?  and most likely for the purpose to preserve the points ?

The capacitor for the points is located on the plate under the distributor cap.  The one on the coil was for noise suppression on the radio.

I just checked mine and it does have the notch as I have read and been told that all ZL/2 hoods required a different coil angle and therefore a different coil bracket compared to the flat hood cars. Can anyone confirm this as being correct? My car is unrestored and as far as I know it is the original bracket along with many other original components still on my car.
Also, mine does not have a capacitor and does not appear to have any threads where one was ever installed. I would have to remove it to be absolute.

Have just been reading back at a few old threads on the coil bracket question. I see where John Z and William know of no notch. I also read others like myself that have it on there cars. Mine sure looks original but who knows. I know mine has been on there for many years.

Yes, it is.  TY!
