Re: capacitor

If you're not into factory concours authenticity and originality isn't your objective, you might consider doing NOTHING about your missing capacitors...

These were essentially 'cosmetic' electrical components intended to defray owner complaint(s) of sub-optimum radio reception (noise). In high signal strength conditions like most major metropolitan areas, the effect of these capacitors is quite modest. It's when you're driving under 'fringe' reception conditions that the value of the capacitors begin to make a difference (low signal to noise ratio).

Few of us are regularly driving these classic cars and when we do, it's usually in a 'weekend warrior' situation where we're crusing around town versus going coast to coast in the 'boondocks'. You just might find you don't really need the missing caps for enjoyable radio reception given your driving habits...

Lyle..

NCRS 73-74 JG page 66 Coil Support

It reads:
On MOST radio equipped Corvettes a metal capacitor is screwed to the coil support bracket. A black wire extends from the capacitor to the positive side terminal of the coil.

It doesn't sound like either year '73 or '74 did they all have them?

That wording is like a lawyer would write it up. I would be looking for a capacitor to be on all 73-74 Corvettes. If no radio was installed then maybe the capacitor would have been not installed.

Re: capacitor

Jeff,

Don't want to hijack the thread but I am in need of the correct capacitor also. I do have a part number - 1852715.

The previous owner decided to rip the wire right out of the capacitor! I have the capacitor without the wire if you would like it. I know there is an article in The Restorer on rebuilding these, but if you have a nice one I would love to puchase it.

Thanks, Chris

Re: capacitor

Jeff:

I'm just trying to put on two capacitors and to see if they will work. Right now I have nothing and I figured I would try something. If you have capacitors with the numbers of the previous posters, lets try those. I sense a certain reluctance to send the capacitors. Jeff, just reach into the bin and let me worry about their effectiveness. Don't worry, I'm pretty sure that two small installed capacitors aren't going to do major damage to anything. Thanks for your time.

Re: capacitor

I will dig through this weekend and make a note of the numbers.

Some must be very common, and some may be very rare.
Sold off a bunch of the 452's recently to the Camaro/Chevelle guys.
I was shocked to find their worth.

Steven - send me your address.
If you just want to try some - I am sure I have a bunch of later style replacements that I would send you for free.

Then if that solves your problem - we can figure out which ones you need.

Thanks a lot. I've pm'd you with my direct email address and home address. Thanks again.

For all that have asked...
I am working on figuring out what I have

Re: capacitor

What does the mounting bracket for the coil's radio suppression capacitor look like?

Looking at the photo in post 22, I suspect it looks like the brackets in the plastic bags on the left side (one mounting hole). A drawing in AIM U69-A4 for 1970 shows one hole also.

The bracket on my '70 has 3 holes like the brackets in the box. These brackets look like the same ones used to mount the capacitor inside the distributor.

If the mounting bracket for the radio suppression capacitor should have one hole, is the end its mounting ear square or rounded? Both types are shown in the photo.

Thanks guys. I'm trying to cleanup some details with the installation of my ignition.

Re: capacitor

Mark,
Heres a pic from one side, I don't seem to have a pic from the back. There should be a single screw holding the capacitor bracket to the coil bracket.

Re: capacitor

Thanks Chris. I know there's a single screw. But what does the capacitor's mounting bracket look like?

Re: capacitor

Todd, just picked up one @ Kississmee in the swap meet area of the Winter Regional.

I believe the vendor was Corvette Cosmetics. Don't know where they are out of.

Repo new part for $29.95.

My 1973 LS4 doesn't require one for Flight Judging according to the 73-74 NCRS JG, but I thought maybe I can avoid some future heated disscussions.

For your alternator. Try finding the correct part # and date code alternator for your car (I believe it is on just the center case)as a core and have it rebuilt.

Corvette Cosmetics is in Vincetown NJ and is owned by Glen Brown 609 268 2288. Long time NCRS member and a great guy with lots of corvette info. Mostly new parts, but some old parts. Always worth asking Glen for some rare parts

Re: capacitor

Mark,
These pics should show how it attaches .

[Mark E.]

Re: capacitor

Thanks Chris.

So the bracket for the cap mounted on the coil is the same as the one for the cap inside the distributor, which has three holes.

And it's not like the single hole brackets shown in post 22.
