Accessory part on ignition coil

[William Morgan]

There is an odd object connected between the negative post and ground on the ignition coil on my 273 V8 1967 Barracuda. It looks like a capacitor/condenser but I can't find any reference to such an item in any parts catalogs or manuals. And the wire intended to connect it to the coil has broken off so finding a replacement is likely somewhat important. I first thought it was some version of a ballast resistor, but it surely looks like a condenser of the type inside the distributor. Any idea what it's for and where to get a replacement?

It is a noise suppressor. Look in the Accessory section of the FSM.

If you have points it might still be needed. If you have electronic probably not needed .

They are still available.

Here is one

There's also one on the back of the gauge panel attached to the IVR.

Thanks, Dana. That sounds like what I needed to know. I'll check it out.

You can run without it but might notice noise on an am radio

A noise suppression condenser goes to the +ve terminal, not the -ve terminal.

If it IS connected to the -ve terminal, & the dist is points ign, it will cause erosion of the points surface.

 

[William Morgan]

Well, it WAS connected to the negative terminal, but it won't be connected to either in the future! I don't know who placed it there or when, but I don't need it now that I know what it is. Thanks for your info.

Make sure you have a condenser INSIDE the dist. It may have been removed & the external cond fitted as a stop-gap meassure.

& the external cond fitted as a stop-gap meassure.

The external is an oem standard part

That connects to the -ve terminal?

No I thought you were referring to the OEM noise filter on the coil
