Mine certanly has a ballast - but does the OP's car still have points? If not the wire may be "surplus" and not longer needed if an electronic ignition of some form has been added.

Thanks for info but the problem has been sorted. My only question is that I have this connector which is like a small bolt with threads which slides in a female and are both covered by two separate rubber boots. This is like a fuse holder but instead it is a threaded bolt . This is on the negative side from the coil to the distributor. All I wish to know is the function of this so that I can eliminate it . I have carefully noted all the comments in this thread. I just wish I can send a photo of the part to someone who is technical and maybe he can tell me what it is

Send Me the photo wmbutton@gmail.com and I will try to help.

Can you advise the location of the 'threaded bolt'
Normally the coil has two 'threaded bolts' one that is connected to +12 volts when the ignition is turned on. The other 'threaded bolt' is on the negative side of the coil and connects via a cable to the distributor, inside the distributor there is a switch (contact breaker) that makes and breaks a circuit and connects to 'ground' ( 0 volts) and passes a current through the coil, which then creates the high voltage on the high tension side of the coil, and the spark at the spark plug
In some cases the wire connections to the coil 'threaded bolt' is by way of a female connector in a rubber boot, that pushes down onto and over the 'threaded bolt'. This type of connection was also sometimes used on fuel pumps, it probably works well when first fitted, but can give connection trouble later in life.

The chap making the inquiry sent Me a picture of the item. Not Lucas, Ford or Morgan so far as I could tell. I told Him to cut it off and use a electrical fitting like one of the others now in use. I think it was a "thru bulkhead fitting" but really do not know. I would send a picture but I too have trouble with simple computer instructions.

The connector is in between the terminals from the negative of the coil to the distributor. I have been told today the this is common on ford 1600 engines and I am sure I had seen it before in photos. Someone has told me it could be a resistance but when I checked with the multitester I found that there is continuity either way. Maybe someone with a Ford engine 1600 will see this thread . Thanks again
