capacitor

[Todd L.]

Looking through my AIM for a 74', there is a capacitor that is attached to the coil. Any idea where I would get the assembly?

On another note, my alternator is incorrect and bad. Since it needs to be replaced, anyone know where to get a correct date coded alternator for a 74' LS4 w/AC?

For Alternators - try John Pirkle
he's in the driveline

Re: capacitor

Does anyone know the rating on the capacitor? I could probably make one if I had the specs.

Todd

Thanks Jeff.

Re: capacitor

Why would you want to make one?

If you don't care about originality...
Just get one at Pep boys for a only few dollars.

Or find out exactly what you need - I have shoe boxes full of those things.

Re: capacitor

The RF capacitor used on the ignition coil for radio equipped cars was Delco Remy PN 1947452 with a storage rating of 0.3 uF.

Jeff:
I'm looking for the capacitors for the coil and voltage regulator. Don't care about the numbers. If you have them, let me know what you want for them. Thanks

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.

Re: capacitor

If you don't care about the numbers.
Those can be found at Pep boys for not much at all.
Or repros are available too.
The originals tend to get a little pricey.

Re: capacitor

Jeff:

If you have a few of the older ones, are you willing to sell a few?
If so, let me know.

Re: capacitor

let me know which numbers you need - i can dig through a bit this weekend.

Re: capacitor

That's one my problems. I don't have the numbers. I'm missing the capacitors for the coil and Volt reg for a 59 283. Anything that will work would be appreciated.

I don't have my judging manual with me and don't recall seeing a 454 without a capacitor. Is this for a car with no radio or all 454's? What does the manual say?

Re: capacitor

I am not sure about this.
If any of them would work - why did GM keep changing the number?
I would feel funny about reaching in to the bin and just sending you any old thing.
I need to narrow it down a bit - I have 100's of these.

Re: capacitor

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?

Re: capacitor

RF capacitor part numbers changed based on several aspects of the part:

(1) Electrical specs (storage capacity and working voltage).

(2) Physical configuration (some were packaged with captive mounting tab, others had separate, discrete mouting bands; some were packaged in metal cans others were simply wax dipped).

(3) Lead wire (specific length and type of connector).

(4) Insulation (early caps used a simple phoenolic insulator with a hole for the lead wire to run through; later versions were 'improved' with a rubber pyramid insulator that provided strain relief to the lead wire to thwart fracture based on side loading).
