MG MGB Technical - New coil installation

I have a new coil and new leads. I don't know how to connect the coil lead to the coil. The photo shows what I have - what do I do with them? The lead is copper core and the coil is a lucas style 12V coil.

It would be obvious if I had the original one for comparison, but I don't.

Over to someone patient and understanding!!

John. Slip the threaded part over the lead, cut back a bit of the insulation and put the wire exposed through the washer. Bend the wires back so they hold the washer on and then screw the lead into the coil. However, most coils nowadays don't use the screw in type, they use a spring fitting arrangement to hold the wire in the coil with a rubber moulding to cover it all up.

Thanks for that Tony. I'd seen something about the "new type" but not the screw in type.

It is an older method for both anchoring the wire into the coil and making sure that all strands are in contact with the coil top socket connection.

The best method is to take the strands and after inserting them thru the hole in the large copper washer, fan them out so that they radiate from center in a circular pattern, like spokes from a hub, then insert this assembly into the coil top, and screw down the plastic fitting until it bottoms against the washer. This will hold the wire/strands in place and make as good a connection as possible.

I would go one step further. Just put a drop of solder on the wires you bend over. It stops them from pulling out which they will. Cut the insulation so the wires show less than 1/4 inch. Otherwise after soldering the end you will have to clip the over long wires.

With 20Kv flying around just fanning them works fine. I have never had a problem at the HT end of the coil. I am using Bosch silicon rubber leads now, they have been on for years and cope fine with the 45 thou gap for the Classicheads electronic ing.

I've been using silicone rubber HT leads for over 30 years. The only failure I've had was a curious one on the roadster where one of the brass connectors developed a blue coating that blocked the HT and resisted scraping off. The ones on the V8 have seen 75k and 13 years so far. They are miles better than the carbon string which start going high-resistance almost immediately, the silicone being very stable, and significantly cheaper as well.
