1971 Norton Commando With Mismatched Coils

I bought my Commando a couple years ago in milk crates. 1000's of pieces. Last fall I finally got it running after a long summer of painting and building.

It was hard to start and seemed to be firing on only one cylinder. I have since resolved the problem, but I want to know some information.

I have two different Coils, one looks like every replacement coil that you can get anywhere, where you push the spark plug lead straight into it. The second coil, the connector comes off the coil at a 90 degree angle and has a screw in type connector. My question is, how do you properly connect the plug lead to this type of coil with the screw in part that connects to the coil?



I will post a short video of the bike running sometime this week. It was quite the rush getting it running as I have never done any kind of mechanic work before, and built the bike from scratch. It is an amazing feeling. A few more things to tie up before I can try to ride it. (I am 35 years old and have never rode a bike before)

Typically you would unscrew the cap, put the end of the HT lead through it and then solder on a small brass disc with a hole in the middle specifically made for this application, the HT cable cannot pull through the cap and is held in place when the cap is screwed in. I think I have some at home somewhere.

That is the exact information I was looking for. I am sure I can rig something up. Thanks!

I'm currently away on a trip, but I willhave a look when I get back to see if I have any in the workshop, I can easily put a couple in an onvelope if I find them, I sometimes have to use this method repairing vintage cars.

But could it be a 'screw in' type HT fitting with a threaded 'spike' that the HT lead screws onto, similar to a plug cap.

Cool thanks. If you can find some I would love it.
